INTRODUCTION
The Wind River Range (WRR) is a mountain system in the central portion of the Rocky
Mountain cordillera, located in west-central Wyoming. Ranging in elevation from 5,500 to 13,800
ft., it occurs as a large massif of extensive forests, subalpine and alpine meadows, and alpine rock
and ice, bounded on three sides by desert basins, including the Green River, Wind River, and Great
Divide basins (Daubenmire 1943; Wells et al. 2011). Geologically, the WRR represents a large,
north-south doubly plunging, asymmetrical anticline; the modern landscape was formed as a result
of billions of years of geologic activity, including magmatism, tectonism, sedimentation and
erosion (Blackstone 1993). The WRR lies in a rain shadow created by the Salt River and Wyoming
Ranges to the west and the Teton and Gros Ventre Ranges to the northwest. These ranges
significally reduce the amount of precipitation in the WRR (Massatti 2007). The region is generally
characterized by a very dry continental climate, with frequent summer droughts, and seems to be
quite unhospitable for non-vascular plants. Nevertheless, like in any other mountainous terrain with
a complicated geological history and huge range of elevations, there can still be found a great
variety of ecological niches that can potentially house a number of interesting liverworts and
mosses.
With this work, we continue a series of technical reports on the research project “Bryophytes
inventory of the east slope of the Wind River Range, Shoshone National Forest, Wyoming”, started
in 2011.
A bryophyte inventory of the east slope of the WRR was conducted in 2011 through 2014.
Field work was carried out during three collecting seasons:
1. from August 6 to August 14, 2011 - within 42°25.800’-42°44.350’N & 108°35.400’108°53.150’W, at elevations 6800-9800 ft., or approx. 2070-2990 m. Quads.: Sinks Canyon, Louis
Lake, Limestome Mtns.; South-Central & Southeast regions.
2. from July 28 to August 9, 2012 - within 42°35.150’-42°52.100’N & 108°50.900’109°04.450’W, at elevations 7200-9600 ft., or approx. 2200-2930 m. Quads.: Sinks Canyon, Louis
Lake, Dickinson Park; South-Central & Southeast regions.
3. from July 14 to July 26, 2013 – within 43°28.602’-43°46.704’N & 109°48.592’110°04.229’W, at elevations 7600-9600 ft., or approx. 2300-2900 m. Brooks Lake Quad. and the
south-eastern area; North, Northeast & North-Central regions.
Totally, approximately 3500 voucher specimens of bryophytes were collected by the author
from more than 150 sites, also 1000 GPS measurements were made.

The major part of the study area is located within Fremont County of Wyoming. By the
beginning of our research the bryophyte flora of Fremont County had been one of the most poorly
documented in the state.
As a result of our bryological explorations of the east slope of the WRR, 176 species of
bryophytes from 92 genera and 41 families were revealed based on the author’s fieldwork. The
checklist represents the first conspectus of the bryophyte flora ever composed for this portion of the
Wind River Range. 8 species and 1 variety constitute state records for Wyoming. 117 species and 6
varieties are novelties for Fremont County; 18 species and 6 varieties are new to Teton County. At
least 33 rare and interesting species were documented. The bryophyte flora of the E WRR is
boreal-montane with arctic-alpine and arid elements, distinguished by a high percentage of
calciphiles.
On the criteria of the richness of the bryophyte flora and presence of rare species in plant
communities, 6 sites of potential conservation concern were revealed: 1) Canyon Creek: subalpine
fen-E, 2) Sand Creek boggy valley-W, 3) Ranger Creek boggy valley-SW, 4) Twins Parks Creek
boggy valley-SW, 5) Dickinson Creek boggy valley-SW and 6) Wind River Lake.
The present report is provided with 150 of the author’s illustrations: photographs of landscapes
and ecotopes of the study area and close-up images of bryophytes. 6 photos of the specimens:
Paludella squarrosa YeKA 12841, Scorpidium scorpioides YeKA 12977, Sphagnum angustifolium
YeKA 13397, S. warnstorfii YeKA 13456 and Syntrichia ruralis YeKA 13352 (Figs. 54, 57, 66,
69, 70, 72) were made by Belinda Lo.

STUDY AREA: A BRIEF OVERVIEW OF GEOGRAPHIC REGIONS
The area inventoried lies within five geographical regions based on localized differences in
substrate, geology and topography: South-Central and Southeast regions (further referred as SE
WRR), and North, Northeast and North-Central regions (further referred as NE WRR).
SE WRR. The most arid portion of the east slope. The South-Central region “encompasses the
land in the southern half of the area within Shoshone National Forest and west of the sedimentary
formations. This region is drained primarily by tributaries of the Popo Agie River that eventually
enter the Wind River; several small streams at the southern end of this region find their way into
the Sweetwater River… A significant portion of this region lies below 9,500 feet…elevation
topography characterized by rolling hills and glacial deposits is exemplified by the Louis Lake and
Maxon Basin area, Grannier Meadows, Worthen Meadows, Shoshone Lake, and Dickinson Park...
The Southeast region consistes of land underlain by sedimentary formations east of the SouthCentral region...The sedimentary formations present in the Northeast region run continuously
southeast along the east flank of the Winds through the Wind River Indian Reservation and the
Southeast region, ending about one mile to the northeast of Miner’s Delight…The major peaks in
the Southeast region … Limestone Mountain, the Freak Mountains, Indian Ridge, and Fair Hill are
all less than 9,400 feet in elevation…Similar to the Northeast region, the prevalence of calcareous
soils, especially at higher elevations, lead to a distinctive flora” (Massatti 2007, p. 11-12).
Southeastern portion of the WRR is a botanically interesting region. Its flora represents a mixture
of Central Rocky Mountain flora, and species typical of the Great Plains. The area is unique
because of the predominance of limestone-derived substrates, which causes a high proportion of
calciphiles (Massatti 2007; Wells et al. 2011).
NE WRR. The North region is unique to the area as the soil parent materials were influenced
by the volcanic activity in the Absaroka Mountain Range. It extends from Togwotee Pass south to
Union Peak and includes all of the land that is underlain by variegated bentonitic claystone and
tuffaceous sandstone (Love & Christiansen 1985). Breccia debris / conglomerates of volcanic
origin are scattered all across the area (the author’s observation). The region is composed of
relatively low and rolling hills and basins primarily below 10,000 feet in elevation. Tributaries of
the Wind River, including Warm Spring Creek and Sheridan Creek, drain this area. A park-forest
vegetation mosaic is common throughout the landscape, especially closer to the Continental Divide
(Massatti 2007). The North-Central region stretches from Union Peak south to the southern
terminus of the Fitzpatrick Wilderness and east either to the Wind River Indian Reservation or the
sedimentary formation of the Northeast region; elevations range from 9,500-13,800 ft. Snowmelt
and the large complex of glaciers feed the major drainages; these drainages drain into the Wind
River. Soils are formed primarily from granites, migmatites and gneisses. Hundreds of lakes and
wetland complexes are scattered throughout. (From: Blackstone 1993 & Massatti 2007). The
Northeast region encompasses all of the land underlain by sedimentary formations flanking the east
slope of the Wind River Range north of the Wind River Indian Reservation. The predominant
5
formations are Madison and Gallatin limestones, Bighorn dolomite, Flathead sandstone; elevations
range from 7,300-11,700 ft. The region is distinguished from the North and North-Central regions
by the prevalence of calcareous soils that account for a distinctive flora (Love & Christiansen 1985;
Massattii 2007).
Within the Wind River Range four elevation zones can be delimited: the foothill zone from
5,500-8,000 ft., the montane zone from 8,000-9,000 ft., the subalpine zone from 9,000-10,500 ft.,
and the alpine zone from 10,000-13,800 ft. (Daubenmire 1943).

Checklist of bryophytes
The following list is composed on the basis of approximately three thousand collections from
the east slope of Wind River Range (west-central Wyoming), made by the author within the period
of August 6-14, 2011, July 28 – August 9, 2012 and July 14-26, 2013. A total of 176 species from
92 genera and 41 families were revealed in the bryophyte flora, representing two phyla:
Marchantiophyta, or liverworts - 26 species, 18 genera, and 12 families, and Bryophyta, or mosses 150 species, 74 genera, and 29 families (Table 1). The flora is predominantly boreal-montane, with
arctic-alpine and arid elements (the latter is mainly represented by Grimmiaceae and Pottiaceae
families). The most representative families of the bryophyte flora are: Amblystegiaceae (includes
21 species), Brachytheciaceae (15), Bryaceae (11), Grimmiaceae (11), Pottiaceae (9),
44
Mielichhoferiaceae (9), Mniaceae (9), Sphagnaceae (7), Polytrichaceae (6), Dicranaceae (6) and
Scapaniaceae (6). The genera Pohlia (9 species), Grimmia (7), Sphagnum (7), Ptychostomum (6),
Brachythecium (6) are the most diverse taxonomically.

The study area is characterized by a high proportion of calciphiles – more than 60 species, or
about one third of bryophyte flora. Those that are always found on calcareous soils / substrates are
obligate calciphiles, while those that often, but not always, occur are facultative calciphiles. The
latters predominate in the flora. In the list below we also included species with a weak calciphilic
tendency.

A number of calciphiles sensu lato are found all across study area, especially in Southeast and
Norhteast regions. Wide distribution and taxonomic diversity of acidophilic / oxylophilic species
were revealed in Dickinson Park, the region of prevailing granite rock (granite bedrock). The group
of the most typical acidophilic species includes Cephalozialla rubella, Polytrichum strictum,
Sphagnum angustifolium, Sphagnum fuscum, S. russowii, Straminergon stramineum, etc.

In the checklist, bryophyte species and genera are arranged alphabetically within the families of
two principal bryophyte subdivisions - Marchantiophyta and Bryophyta. Specific Latin name is
followed by the name of its site and the specimen / representative specimen number. General
comments on taxa distribution and ecology are given. Taxa new to the state are marked with “!”.
Rare species (“®”) are provided with proper comments. Calciphiles are marked with asterisks
(“**” – obligate calciphiles, “*” – facultative calciphiles). The classification and nomenclature of
bryophyte taxa follows Goffinet & Shaw (2008) and Flora of North America (2007, 2011,
http://www.mobot.org/plantscience/bfna). The synonyms for some taxa are given. Global
conservation status is indicated for each species (except for those with poorly known distribution).
Specimens are deposited at the RM (see: www.rmh.uwyo.edu/data/search.php ) and the author’s
herbarium; if they are else where the herbaria are noted (BING, CAS, COLO, DUKE, MO,
MONTU, UC, VBGI).

In the future, I am intending to add to my list more interesting species from the backlog of
specimens I have collected in the E WRR within the framework of this project. Of about 3500
specimens, at least a hundred still need some additional ID work / more meticulous microscopic
studies and, if necessary, genetic analysis. I expect that some of the determinations will require
revision, especially with the extensive revision of genera since volume 27 of the Flora of North
America was published in 2007. (Revisions of many genera – pleurocarpous mosses, liverworts and
the rest of groups of acrocarpous mosses, uncovered in volume 27 - will be made in volumes 28 &
29, which are not published yet.)

Gott. et al.; M. polymorpha L. subsp. montivagans Bischl. & Boisselier]. G? Thalloid liverwort.
Arctic-alpine taxon with European-Siberian-American distribution (Shlyakov 1982). In Wyoming
and Colorado, it occurs at subalpine and alpine elevations, on the edges of streams and rills, on fens
(Weber & Wittmann 2007, Lenz 2011; Kosovich-Anderson 2011, 2013a). In the E WRR, it is
frequently encountered in shaded niches along streamsides on wet clay, sandy and peaty soils. M.
alpestris can be distinguished from common M. polymorpha by its lack of a darkened midrib, and
its thallus is also thicker, fleshier and broader. The species was not previously mentioned for
Fremont & Teton Cos. Figs. 17-18.

3. M. polymorpha L. G5. A cosmopolitan thalloid liverwort occurring in damp to wet habitats;
common in man-made habitats as a weed, on soil and rock, by streams and rivers, on road sides,
walls and paths (Frey et al. 2006). In Wyoming, it occurs along streamsides from the plains to the
montane, becoming rarer in the subalpine; replaced at higher elevations by M. alpestris. M.
polymorpha L. sensu lato (including M. alpestris) was reported by Porter (1937) and Hong (1977)
from 12 counties of Wyoming - Albany, Carbon, Crook, Fremont, Johnson, Lincoln, Park,
Sheridan, Sublette, Teton, Uinta, Weston Cos, and Grand Teton and Yellowstone National Parks.
In the E WRR, I observed a rare phenomenon: M. polymorpha as an epiphyte on Fontinalis
antipyretica growing on granite stones in the splash zone of Slate Creek. Fig. 19.

*/**4. Preissia quadrata (Scopoli) Nees G5. Thalloid liverwort. World distribution of this species
is arctic and temperate areas of the Northern Hemisphere; it occurs on mineral soil, more frequently
in calcium-rich sites, especially near watercourses, extending to subalpine and alpine elevations
(Schofield 2002). In Colorado, the species is frequent on packed moist soil, especially along
seeping cliffs (Weber & Wittmann 2007). In Wyoming, Preissia quadrata was reported by Porter
(1937) from Albany, Sheridan, Sublette Cos, and Yellowstone National Park. It was found on
shaded walls of ditch on Canyon Creek subalpine fen (SE WRR). The species is new to Fremont
Co.
The sporangium-bearing receptacles of P. quadrata are regularly 4(5)-lobed and somewhat
angled on the margins. Figs. 34-36.

Conocephalaceae
! * 5. Conocephalum salebrosum Szweik., Buczk., Odrzyk. G? Thalloid liverwort. Recently
described species related to the widespread C. conicum (L.) Dumortier, distinguished on a genetic
and morphologic basis. According to Szweykowsky et al. (2005), C. salebrosum is a Holarctic
species occurring in Europe, East Asia and North America. In Colorado, it is “a common species
along small streams in the foothills and montane zones. … The two species differ in the shiny
surface of the former and the matte surface of the latter, as well as fundamental differences in the
structure of the pores” (Weber & Wittmann 2007, p. 161). As recent studies show (Borovichev et
al. 2009), C. conicum is predominantly a boreal-temperate European-Siberian species collected
more often below 600 m and not found above 1080 m, whereas C. salebrosum can be characterized
as an arctic-boreal circumpolar species known from higher elevations. The plants occur on
sandstone, shale or slate walls, or calcareous seepages, on streambanks on in swamps. On my
observations, it is rather common in Wyoming in proper situations. It was registered in northern
portion of the E WRR.

Ricciaceae
6. Riccia glauca L. G? Thalloid liverwort. On Schuster (1992), the distribution of Riccia
glauca is “imperfectly Holarctic”; it’s known from cool to warm but not frigid regions. In North
America, the species was found principally in the West, from Washington and Oregon south to
California, east to Wyoming and Arizona where it’s sometimes relatively frequent, occurring as
isolated, complete, conspicuous rosettes on exposed soil, on moist silt, along rivers subject to
inundation, on mud of pond margins. In Wyoming, it was reported for the first time from Sublette
Co (Porter 1935). New to Fremont Co. One population of the species was found on drying clayey
shores of unnamed lake along Christina Lake Trail. Fig. 47.

7. Pellia neesiana (Gottsche) Limpricht G5. Thalloid liverwort. A species with boreal or
hypoarctic circumpolar distribution (Shlyakov 1976). It’s rather common in this portion of the
Rocky Mountains: frequent in Idaho and Montana (Hong 1977); known from a variety of wet sites,
including streamsides, willow carrs, and edges of pools in the subalpine in Wyoming and Colorado
(Weber & Wittmann 2007; Lenz 2011; author’s data). New to Fremont Co.

*
8. Aneura pinguis (L.) Dumort. G5. Thalloid liverwort. Almost cosmopolitan species.
Facultative calciphile. In Western North America widespread from Alaska to California; growing
on damp rock, peat, or squeezed in among other bryophytes, usually in moist areas, from sea level
to alpine, but not richly represented in collections because plants without sporophytes are seen most
frequently and not collected (Schofield 2002). Common in Wyoming, Colorado, Idaho and
Montana (Hong 1977). In Dickinson Park, it was found on subalpine fen, among living Sphagnum
mosses. New to Fremont Co.

Pseudolepicoleaceae
9. Blepharostoma trichophyllum (L.) Dumortier G5. Leafy liverwort. Hypoarctic-boreal
circumpolar species with bipolar distribution; hygro-mesophyte, occurring on shaded rocks, peaty
banks, soil covered ledges and decaying wood, under constant moisture and relatively diffuse light
(Shlyakov 1979). B. trichophyllum is a very small, slender, pure green liverwort, with very peculiar
hair-like leaves so that it can be mistaken for a film of green algae. It’s been reported from
Wyoming, Colorado, Idaho, Montana and South Dakota (Hong 1977; Weber & Wittmann 2007).
On the author’s observations, B. trichophyllum is one of the most common liverworts in dark
coniferous forests of Wyoming. Lenz (2011) reported it from Bighorn Mtns. It was previously
known in Fremont Co from West Fork Lane Creek; also reported from Ablany, Carbon, Park,
Sheridan Cos (Hong 1977; Kosovich-Anderson 2011; author’s unpublished collections). In forested
areas of SE WRR (mainly, in Dickinson Park) and NE WRR, I made a number of collections from
typical ecotopes. New to Teton Co.

Phylum Bryophyta, or Mosses
Class Sphagnopsida
Sphagnaceae
® 27. Sphagnum angustifolium (C. Jensen ex Russow) C. Jensen G5. This species is the only
representative of bryophytes included in the official lists of threatened, endangered, and sensitive
plants of Wyoming (USFS Region 2 - Sensitive). We believe the distribution of this species in
Wyoming has been studied insufficiently to describe it as rare or threatened. S. angustifolium is
considered to be one of the most frequent species in arctic and boreal zones of Holarctic (Ignatov &
Ignatova 2003). Frey et al. (2006) characterize it as the commonest peat moss in circumboreal bogs,
especially in continental regions. On McQueen & Andrus (2007), this species is distributed all
across North America, occurring at low to high elevations, as carpets, floating mats, low hummocks
and hummock sides in a wide range of habitats - from ombrotrophic to rather rich fens, open mires,
sedge fens and muskeg.
On Eckel (2013), S. angustifolium is characterized by “a boreal distribution extending down into
states just north of those bordering the southern United States and absent from the central plains
states”. S. angustifolium is the most abundant and characteristic species of iron fens in southwestern
Colorado (Weber & Wittmann 2007). It is known from western Montana on collections from
Beaverhead, Lincoln and Missoula Cos and Glacier National Park (Elliott 1993). In Montana, it is
considered to be a species of concern with status S2 (Montana Field Guide). The species was
previously known in Wyoming from north-western and northern parts of the state: Beartooth
Plateau (Heidel et al. 2008; Kosovich-Anderson 2011; W. Weber’s collections of 1973, Weber B44268 (COLO, RM)), Bighorn Mtns. (Lenz 2011) and Yellowstone National Park (Lemly &
Cooper 2011).
S. angustifolium in the SE WRR is an interesting novelty for Fremont Co. The population was
discovered in the Dickinson Creek fen, where I found an unusual robust Sphagnum wulfianum-like
form of this species, with a big thickly branched capitula and very long, slender, hanging branches.

28. S. fuscum (Schimp.) Klinggr. G5. Widely distributed in arctic and boreal zones of
Holarctic, mainly confined to ombrotrophic parts of bogs (Ignatov & Ignatova 2003). “The species
is boreal and north to middle American states, with a corridor of absence in the southern and central
plains states” (Eckel 2013). Infrequent in Wyoming; known from montane, subalpine and alpine
fens of the Medicine Bow Mtns. (Porter 1935, 1937; unpublished author’s data), Yellowstone
National Park (Lemly & Cooper 2011) and Bighorn Mtns. (Lenz 2011). The species was found in
shrubby wetlands along Dickinson Creek, on wet sandy (!) soil. New to Fremont CO.

29. S. russowii Warnstorf G5. Widely distributed in arctic and boreal zones of Holarctic;
mainly confined to mesotrophic parts of bogs; moderately acidophilic species (Ignatov & Ignatova
2003). In this portion of the Rocky Mountains, it’s common and occurs in cushions in willow fens
and on wet forest floors, on the edges of fens (Spence 1985b; Elliott 1993; Weber & Wittmann
2007; Lemly & Cooper 2011; Lenz 2011; Kosovich-Anderson 2011; unpublished collections of the
author from Albany and Carbon Cos of Wyoming). Frequent in Dickinson Park, growing in

30. S. squarrosum Swartz ex Crome G5. Widely distributed in arctic and boreal zones of
Holarctic. In North America, its distribution is “boreal-Canadian, temperate American states,
avoiding the southern states and central plains except South Dakota” (Eckel 2013). In this portion
of the Rocky Mountains, the species sporadically occurs in willow and peat fens (Elliott 1993;
Flowers 1973; Weber & Wittmann 2007; author’s data). It was previously known in Wyoming
from five counties: Teton Co (Spence 1985b), Park Co (Kosovich-Anderson 2011); Albany &
Carbon Cos (author’s data), Big Horn Co (Lenz 2011) and Yellowstone National Park (Lemly &
Cooper 2011). The large population of Sphagnum squarrosum was found on subalpine fen in the
valley of Canyon Creek. This is the first record of species for Fremont Co.

32. S. cf. teres Ångström in C. J. Hartman G5. Widely distributed in arctic and boreal zones
of Holarctic; a species of base-rich mires and flushes (Ignatov & Ignatova 2003). In North
America, its distribution is “boreal-Canadian, temperate American states generally with a southern
states and plains state’s corridor where is it absent” (Eckel 2013). In this portion of the Rocky
Mountains, Sphagnum teres has not been studied enough to estimate whether or not it is common,
largely because of confusion with some forms of S. squarrosum. Porter (1937) and Lemly &
Cooper (2011) reported S. teres for Yellowstone National Park, Lenz (2011) listed it for Bighorn
National Forest. Several occurrencies are known from Carbon and Sublette Cos (Porter 1937;
Cooper & Andrus 1994). In the E WRR, the species was collected on subalpine fen in the valley of
Canyon Creek. New to Fremont Co.
SE WRR: Canyon Creek: subalpine fen-W: ## 10914, 10920.
33. S. warnstorfii Russow G5. Widely distributed in arctic and boreal zones of Holarctic;
normally forms dense lawns in rich, open and forested fens (Ignatov & Ignatova 2003). It is green
or yellowish-green in the shade but red to purplish-red in the sun. In my opinion, his is the most
common Sphagnum in Wyoming, known at least from 5 counties of the state - Albany, Carbon,
Washakie, Park, Big Horn Cos, and Yellowstone National Park (Porter 1937; Lemly & Cooper
2011; Lenz 2011; Eckel 2013; Kosovich-Anderson 2011, 2013a; unpublished author’s collections).
Sphagnum warnstorfii is very abundant in hummocks on eutrophic fens of the SE WRR; it’s
represented by its typical “Wyoming form” (see below). This is the first record for Fremont Co.
Fig. 72.
Specimens from Wyoming, including those collected by the author in the SE WRR, have several morphological
features: elliptic pore-like wall thinning and ruptures at the distal ends of the cells of stem hyalodermis vs. absent pores
in typical form plus fibrillose hyaline cells in distal portion of stem leaves vs. efibrillose in typical form. In many cases,
Wyoming plants of S. warnstorfii have unclearly 5-ranked arrangement in branch leaves vs strongly 5-ranked in typical
form. Eva Mikulǎškova, a Czech researcher, was studying the genetic structure of six samples of S. warnstorfii from
Wyoming (all six from the author’s herbarium); she found that they appeared to be pretty typical S. warnstorfii. (J.

distributed species known in pre-polar provinces of both Hemispheres, as well as in high elevation
areas of all continents (Ignatov & Ignatova 2003). It’s typically associated with a large number of
mosses of wet soil cover in subalpine forests and alpine tundra and fens. On Weber & Wittman
(2007, p. 117), in Colorado, it’s “a characteristic, usually dwarf, plant of the wet tundra, especially
in late snow areas and on frost-push hummocks”. Very common in this portion of the Rocky
Mountains (Porter 1937; Lawton 1971; Flowers 1973; Elliott 1993; Weber & Wittmann 2007; Lenz

37. Polytrichum juniperinum Willdenow ex Hedwig G5. A well-known cosmopolitan and
almost weedy moss, occurs on all continents. As Ochyra believes, “it is actually a bipolar species,
common in polar to temperate areas of both Hemispheres with some intermediate montane stations
in the tropics” (Ochyra et el. 2008, p.107). In this portion of Rocky Mountain region, abundant and
widely distributed from the foothills through the alpine (Lawton 1971; Flowers 1973; Elliott 1993;
Weber & Wittmann 2007; Eckel 2013; Kosovich-Anderson 2011, 2013a). Very frequent in
Wyoming, inhabiting a variety of substrates, including disturbed ones, but tends to avoid
excessively dry or exposed sites (Porter 1937; Eckel 2013; author’s data). In the E WRR,

temperate areas of both Hemispheres with some intermediate montane stations in the tropics
(Ochyra et el. 2008). It prefers sunny situations and normally grows on shallow well-drained sandy
or gravelly soils over rocks and boulders; it’s also characteristic for road cuts, old fields, burned
63
areas, rocky ridges; in dry alpine tundra and late snow areas northward, it’s often associated with
lichens. Polytrichum piliferum is very common in Wyoming and adjacent states (Porter 1937;

39. P. strictum Menzies ex Bridel [Polytrichum affine Funck, P. juniperinum var. affine
(Funck) Bridel]. G4. A species widespread in the boreal regions of Holarctic occurring on bogs and
fens, in moist alpine tundras, on rotten stumps in wet coniferous forests, etc. (Frey et al. 2006).
Ochyra characterizes it as “a bipolar species, widespread throughout much of the Holarctic,
especially in the arctic and boreal zones, becoming rare southwards and roughly extending as far as
the boundary of Sphagnum-dominated peat bogs with which it is mainly associated” (Ochyra et el.
2008, p. 111). Polytrichum strictum is sporadically distributed in Wyoming where it’s known from
collections made in Albany, Big Horn, Crook, Park, Sheridan, Sublette Cos and Yellowstone
National Park (Nelson 1900; Porter 1937; Lenz 2011; Lemly & Cooper 2011; Eckel 2013). The
author collected it in alpine fens of the Beartooth Plateau (Kosovich-Anderson 2011). P. strictum
may be found in Wyoming in relatively dry portions of shrub-dominated fens with Sphagnum
cover, in hummocks, associated with Aulacomnium palustre and Sphagnum species. Acidophile.

41. T. megapolitana Hedwig
*/** subsp. bavarica (Hessler) Brassard G5. This species with worldwide distribution (including
North America, Eurasia, North Africa, Atlantic and Pacific Islands) is represented in Wyoming by
subsp. bavarica which normally occurs “in mesic, calcareous, open or well-vegetated Arcticmontane sites, or in nutrient-rich sites such as the bases of cliffs or around large boulders”
(Brassard 2007, p. 168). In Wyoming, subsp. bavarica was previously known from Albany, Big
Horn, Park and Sheridan Cos (Porter 1937; Eckel 2013). Apparently, the calciphilous subspecies
bavarica is not infrequent in the SE WRR. This is the first record of the species for Fremont Co.

Encalyptaceae
* 42. Encalypta rhaptocarpa Schwägrichen G4G5. A species with bipolar range, distributed all
across Holarctic, but in some areas it is infrequent: in many continental regions of Asia and in the
Arctic this is the most common species; in plains, Encalypta rhaptocarpa is absent or extremely
rare (Ignatov & Ignatova 2003). It usually occurs in small tufts in rock crevices or over mineral soil
on rock ledges or cliffs, or on bare ground in tundra. In Wyoming, it can be found from the foothills
through alpine (author’s data), but it’s not been studied enough to estimate whether or not it is
common. Porter (1937) reported it from Albany, Carbon and Sheridan Co. In the E WRR, I made
several collections of this species, all with sporogones.

substrates. In North America, the underlying substrate where populations have been collected is
typically limestone” (Horton 1983, p. 428). In Wyoming, the species has not been studied enough
to estimate whether or not it is common. In the SE WRR, it was collected several times from
calcareous soil; all collections with sporogones. New to Fremont CO.

** 44. E. vulgaris Hedwig G5. A species with worldwide distribution: North, Central and South
America, Eurasia, Africa, Pacific Islands, Australia; occurs on shallow calcareous soil over rock
(Magill 2007). On Weber & Wittmann (2007), in Colorado, it is common in rock crevices in the
foothill canyons and up to bare ground in the tundra. Apparently, in Wyoming, it’s encountered in
same situations, but it’s not been studied enough to estimate whether or not it is common. In the E
WRR, the species is rather frequent, occurring on shaded calcareous substrates.

45. Funaria hygrometrica Hedwig G5. Cosmopolitan, one of weedy mosses in the world; it
occurs on packed earth, recently disturbed forest soils, burned areas, pasture places, sidewalk
cracks and neglected ground at all altitudes (Frey et al. 2006; Weber & Wittmann 2007). This is an
early colonizer dispersed by spores; can be easily recognized when the conspicuous sporogones are
present. Widespread in Wyoming, reported from Albany, Big Horn, Carbon, Laramie, Park,
Natrona, Sheridan, Sublette Cos and Yellowstone National Park (Porter 1937; Eckel 2013;
unpublished author’s collections on Laramie Co). Apparently, distributed sporadically in the E
WRR, occurring on wet disturbed soils (Fig. 16). First record for Fremont Co.

Scouleriaceae
® 46. Scouleria aquatica Hooker G4. A species with the disjunct distribution in northwest North
America and northern Asia, infrequent across most of its range; global conservation rank G4. On
Churchill (2007), Scouleria aquatica can be found in aquatic habitats, banks or beds of streams and
rivers, on rock, at elevations from 0 through 1900 m. In Wyoming, the species occurs at eastern
edge of the American portion of its range; it is known from isolated locations in Albany, Laramie,
Park, Sheridan & Teton Cos (Nelson 1900; Porter 1935, 1937; Churchill 1985; Spence 1985b;
Kosovich-Anderson 2011; author’s unpublished collections from Albany and Laramie Cos; Eckel
2013). As a species near the edge of its range, it could be potentially sensitive to environmental
change.
The species was found in SE WRR on wet granite rocks in splash zone of Popo Agie Falls, at
elev. 7700-7800 ft., or approx. 2350-2380 m. (! vs. 0-1900 m on Churchill). New to Fremont Co.

Grimmiaceae
*? 47. Coscinodon calyptratus (Hooker ex Drummond) C. Jensen G3G5. North American
endemic species, common and widespread in the dry interior mountain areas of western North
America, occurring from moderate to high elevations, on dry sandstone and granitic boulders and
bedrock exposures, occasionally on limestone and volcanic outcrops (Hastings 2007). In Colorado,
it’s “abundant and characteristic of granitic boulders in the outer foothills in the ponderosa pine
stands, but less commonly occurring up to the highest elevations” (Weber & Wittman 2007, p. 83).
In Wyoming, Coscinodon calyptratus is common on granite rocks, especially in the southern part
of the state; reported from Albany, Big Horn, Campbell, Lincoln, Park, Platte, Sublette,
Sweetwater, Weston Cos (Porter 1937; Eckel 2013; author’s data). In the SE WRR, the species is
represented by a large luxurious form which is especially abundant on granite boulders of Sinks
Canyon (Figs. 5 & 31). New to Fremont Co.

48. Grimmia alpestris (Weber & Mohr) Schleicher G5? Widespread and common on acidic
rock and sandstone in the warm, dry, western interior of North America, occurring from moderate
to high elevations (Hastings & Greven 2007). The species is probably common in Wyoming. First
collections in the state were made in 1898 by Aven Nelson on Centennial Hills, Albany Co (Nelson
1900). The species was also reported from Grand Teton National Park (Spence 1985b). We
67
collected Grimmia alpestris from sandstone debris on the slope of Limestone Mtn. The species was
previously known in this portion of the WRR from collections of F. J. Hermann.

distribution in North America, where it is not uncommon in the northwestern part of the continent
73
but is known from only a few scattered localities in the eastern part”… “The distinctive characters
of this species include the small plants, 2-4 mm high, with squarrose, subulate, acute leaves, and
the slender, cylindric capsules” (Ireland 2007, p. 459). T. cylindricus typically occurs on sandy or
clay soil, in open disturbed sites, bare soil, roadside banks, trails, fields; it can be found at low to
high elevation. It usually scattered among other mosses and therefore easily overlooked. On Ireland
(2007), its general distribution includes: Eurasia and North America (Alta., B.C., N.B., Nfld. and
Labr. (Nfld.), N.W.T., Ont., Que., Yukon; Alaska, Calif., Idaho, Mich., Mont., Oreg., Wash.). The
species is new to Wyoming.

* 66. Dichodontium pellucidum (Hedwig) Schimper G4G5. A species with worldwide
distribution: North America, Eurasia, Atlantic Islands; occurring on wet cliffs near streams,
calcareous (more often) or acidic rock, from low to high elevations (Ignatov & Ignatova 2003). In
this portion of the Rocky Mtns., it occurs sporadically on wet stones in snowmelt streams and cliffs
from the foothills to alpine. Apparently infrequent in Wyoming where it was previously known
from several occurrencies in Albany, Park Cos (Kosovich-Anderson 2011; unpublished author’s

species Dicranoweisia crispula (see below), D. cirrata is more typical for pre-oceanic regions
where it grows at lower elevations. It’s a common species on the Pacific maritime province in
Montana (Elliott 1993). Interestingly, it is also not uncommon in inland areas of Wyoming:
reported from Albany, Big Horn, Park, Sublette, Teton Cos and Yellowstone National Park (Porter
1935, 1937; Spence 1985b; Kosovich-Anderson 2011; Eckel 2013). In the E WRR, I made a

Pottiaceae
* 72. Bryoerythrophyllum recurvirostrum (Hedwig) Chen G5. A widely distributed species
across all continents. “…it is a typical bipolar species having scattered intermediate stations at high
elevations in the tropics. In the Northern Hemisphere, it is a weedy species widespread throughout
much of the arctic, boreal and temperate zones…” (Ochyra et al. 2008, p. 333; global distribution
map: p. 332). In North America, Bryoerythrophyllum recurvirostrum occurs on soil, rock
(limestone, dolomite, gypsum, siliceous), mortar of wall, bark, in tussock tundra, alpine meadows,
bluffs, forested and boggy areas, stream banks, lake shores; at low to high elevations (20-3800 m)

® * 74. Stegonia latifolia (Schwägrichen ex Schultes) Venturi ex Brotherus G4G5. A rare
bipolar species having a strongly discontinuous, arctic-alpine range in the Northern Hemisphere; a
pioneer colonist of bare silt and fine, fairly calcareous soil amongst stones, and on soil-covered
ledges, growing in dry or moist sites (Ochyra et al. 2008; global distribution map: p. 343). In North
America, the species occurs at low to high elevations, growing on soil, trail banks, in tundra, rocky
areas, on tree trunks and mouths of lemming burrows (Zander 2007b). Reportedly, Stegonia
latifolia shows calciphilous tendency. In the Scottish mountains, it occurs on calcareous soil on
rock ledges (Smith 1978). Savicz-Ljubitzkaja & Smirnova (1970) describe the species as
occasionally occurring on carbonate rock.
S. latifolia is a rarely collected species. It’s one of the most tiny mosses of the Pottiaceae family,
growing in very small pale green patches, easily overlooked in the field. In this portion of the
Rocky Mountains, it is known from very few locations. It is listed as a species of concern in
Montana, with conservation rank S1 (Montana Field Guide). In Wyoming, it is known from a
couple of occurrences including one from the Snowy Range (author’s collections). Interestingly,
both population discovered by me in Wyoming - in the Wind River Range and Snowy Range were registered at much higher elevations than reported by Zander – 2600 m (8600 ft.) in the SE
WRR and approx. 3300 m (10800 ft.) in the Snowy Range vs. 2200 m (7200 ft) (Zander 2007b).
The population in the SE WRR is represented by a rare form of species – var. pilifera. The
common variety has rounded or only short-apiculate leaves, but var. pilifera has long hair-points.
My specimen is characterized by numerous well-developed sporogones. This is the first record of
the species in Fremont Co and the first record of the variety pilifera in Wyoming.

shows strong calciphilous tendency (Savich-Ljubitzkaya & Smirnova 1970; Frey et al. 2006). In
this portion of the Rocky Mountains, it’s common on wet soil and moist granite outcrops, as well as
carbonate rocks, also on saturated ground under willows in subalpine fens; widespread in
Wyoming, but less frequent than S. ruralis; reported from Albany, Carbon, Johnson, Park,
Sheridan, Sublette, Teton Cos and Yellowstone National Park (Porter 1937; Spence 1985b; Eckel

® 83. Meesia triquetra (Richter) Ångström G5. A species widely distributed in the Arctic, on
fens in northern part of boreal zone, becoming rare in southern areas where it occurs only on rich
mountain fens (Ignatov & Ignatova 2003). Meesia triquetra is included into Red data books of
many countries of Europe - listed as threatened in Switzerland, critically endangered in the Czech
Republic, Germany, Serbia and Spain; it’s considered to be regionally extinct in Ireland, and
extinct in the Netherlands (Lockhart et al 2012). In Central Rocky Mountain region, M. triquetra is
a rare component of subalpine and low-alpine rich fens, becoming extremely rare farther south. The
species has never been collected in Colorado (Weber & Wittmann 2007). In Montana, where M.
triquetra is known from a number of sites (mainly in north-western part of the state), it is listed as a
species of conservation concern with status S2; USFS agency status: sensitive (Montana Field
Guide).
M. triquetra was registered for the first time in Wyoming in 2006, on collections of Martin Lenz
from Bighorn Mtns. (Lenz 2006). A few years later, the species was found in Yellowstone National
Park (Lemly & Cooper 2011). In 2011, M. triquetra was collected by me on subalpine fens of SE
81
WRR, which was the first record of this species for Fremont Co of Wyoming. In 2012, I discovered
several more locations of this species – all in Dickinson Park.

® * 84. M. uliginosa Hedwig G4. A species distributed in most sectors of the Arctic and boreal
zone of Asia and North America; it occurs mainly on rich fens, moist calcareous soil banks, and
soil covered rock crevices (Ignatov & Ignatova 2003; Vitt 2007). Ochyra characterizes Meesia
uliginosa as a bipolar species having a continuous circumpolar arctic-boreal-montane range in the
Northern Hemisphere, common throughout the Arctic, with decreasing frequency in the southern
part of the Holarctic where it extends as far south as Sikkim in the Himalayas and Sichuan Province
in China; in the Southern Hemisphere the species is known from a few stations in southern South
America and the offshore archipelagoes of the northern Antarctic Peninsula (Ochyra et el. 2008;
global distribution map: p. 494).
A sensitive species, included into Red data lists of many countries of Europe. On Lockhart et al
(2012), M. uliginosa is a vulnerable species in Bulgaria, Germany, Serbia, Montenego, Estonia,
endangered in Ireland, critically endangered in the Czech Republic, Spain, and considered to be
extinct in the Netherlands. M. uliginosa is pretty rare in this portion of the Rocky Mountains. It’s a
species of conservation concern in Montana (with status S1S2). It’s rather rare in Wyoming, known
from very few occurrencies in Albany, Big Horn, and Park Cos (Porter 1935; Kosovich-Anderson
2011; Lenz 2006, 2011). In the SE WRR, M. uliginosa was collected by me on subalpine fen in the
valley of Canyon Creek. New to Fremont Co.

® 85. Paludella squarrosa (Hedwig) Bridel G3G5. A representative of a monotypic genus
growing half-immersed in shallow water of alpine and subalpine fens. Its distribution includes:
Greenland; Canada (Alta., B.C., Man., Nfld. and Labr. (Nfld), N.W.T., Nunavut, N.S., Ont., Que.,
Sask., Yukon); U.S.A. (Alaska, Colo., Iowa, Maine, Mich., Minn., Mont., N.Y., Vt., Wyo); boreal
and Arctic Eurasia (Lawton 1971; Vitt 2007). In many countries of Europe, the populations of
Paludella squarrosa are declining as a result of hydrological and chemical changes in fen habitats.
The species is listed as vulnerable in Switzerland, critically endangered in the Czech Republic,
Ireland, Germany, and considered to be extinct in Britain and the Netherlands (Lockhart et al.
2012). In this portion of the Rocky Mountains, Paludella squarrosa is also rare: it’s listed as a
species of conservation concern in Montana and Colorado. A handful of populations are known in
Albany, Carbon and Park Cos of Wyoming; all of them are restricted to subalpine-alpine elevation
82
fens (Kosovich-Anderson 2011, 2013a; unpublished collections of the author). M. Lenz recently
discovered several stations of the species on Bighorn Mtns. fens (Lenz 2011). I made a number of
collections of P. squarrosa in the SE WRR (mainly, on the Dickinson Park fens). This is the first
record of species for Fremont Co.
P. squarrosa is easy to recognize. It’s a large moss, 4-5 (to 20) cm high; “the leaves are
decurrent and squarrose-recurved, with the outer part folded in such a way as to appear heartshaped” (Weber & Wittmann 2007, p. 108). Figs. 53-54.

Bryaceae
*? 86. Bryum argenteum Hedwig G5. A species with cosmopolitan distribution, occurring from
the Arctic to deserts and equatorial regions; it can be found on various substrate types in a number
of different situations; common in man-made habitats: edges of roads, crevices in pavement, hardpacked soil, etc. “A truly cosmopolitan, ubiquitos [! – YK-A] and weedy moss, occurring
throughout the world, often in anthropogenically influenced habitats including concrete, brick,
thatch, paths and bonfire sites, and common even in large cities owing to its apparent ability to
tolerate extreme atmospheric pollution” (Ochyra et al. 2008, p. 457). In Western U.S. drylands, it
occurs in the open areas with partial shade on soils, rocks, walls, cracks in cement, tree bark, roof
tiles, etc. (Rosentreter et al. 2007). In the E WRR, as well as across the state, it occurs in open or
shaded places on bare ground, at a wide range of elevations. New to Fremont Co.

Almost cosmopolitan species widespread in disturbed areas all across the world, occurring on
various soils, rotten wood, rarely on rocks, sometimes in full and direct sunlight, xerophilic. It’s
very common in cool deserts, in different types of exposed habitats such as trail banks, dry
grasslands, waste places, etc. (Spence 2009). Weber & Wittmann (2007) characterize it as a weedy
moss. In Western U.S. drylands, it occurs on various soils at middle to high elevations; it’s a
common associate of Syntrichia ruralis and Ceratodon purpureus (Rosentreter et al. 2007).
Apparently, the species is common in the E WRR.

fens and bogs, grows along streamlets, lakes and ponds, often on carbonate soils; associated with a
large number of species (Ignatov & Ignatova 2003). According to Ochyra, “although Bryum
pseudotriquetrum is generally considered to be a subcosmopolitan or cosmopolitan species, it is
actually a bipolar moss with intermediate stations at high elevations in the Neotropics and tropical
Africa” (Ochyra et al. 2008, p. 479). Very common in Wyoming and adjacent states (Porter 1937;

on acidic, gravelly or sandy distirbed soil, path banks, stream banks, also on peaty soil; global
distribution (on Shaw 2009): Greenland; Canada (B.C., Man., N.B., Nfld and Labr., N.W.T., N.S.,
88
Ont., Que.); U.S.A. (Alaska, Colo., Maine, Mass., Mich., N.H., N.Y., Vt., Wash., Wis.); Eurasia.
New to Wyoming.
The species was found in sedge (+ grasses) fen along Sand Creek; in wet deeply shaded niche at
base of granite boulder (3 x 4 m²) lying amongst the fen, approx. 10-15 m north of creek, on moist
clayey soil, associated with Polytrichastrum longisetum, Ptychostomum pseudotriquetrum and
Rosulabryum laevifilum.
Plants in all three specimens from the SE WRR have abundant and well-developed gemmae,
typical for this species. “The gemmae of Pohlia bulbifera appear to be round to oblong because the
4-5 laminate leaf primordia are concave and form a dome over the gemma apex. The leaves are
wide-spreading so the gemmae, although small, can be seen slustered in the distal leaf axils” (Shaw
2009).

“The species occurs in a unique habitat of periodically inundated rock surfaces near streams in
dry, montane forests…on ”vertical calcareous rock surfaces and at the bases of Salix bushes just
above rock substrates. On these substrates it occurs in areas subject to periodic inundation by
sesonally high water. In the Wind River Mountains it was collected in a dry stream bed about 2-3 m
wide, and at the edge of a much larger, permanent stream, where it was wet due to spray from
swiftly running water. In both instances Schistidium rivulare (Brid.) Podp. occurred in association.
The two collections were made in montane forests dominated by Pseudotsuga menziesii, Pinus
contorta, and Pinus flexilis” (Vitt 1991).

Fontinalaceae
124. Dichelyma falcatum (Hedwig) Myrin G? A holarctic species distributed mainly in
mountains of Northern Hemisphere; it’s usually attached to stones in cold, rocky streams in high
elevation areas; it also occurs on tree bases and roots, in and along brooks, wet depressions, and
stream banks (Ignatov & Ignatova 2004). Until recently, D. falcatum was known in Wyoming from
Teton County (Spence 1985b) and Park County - W. Weber’s collection of 1973 from the
Beartooth Plateau (Eckel 2013). According to our observations, the species occurs in at least four
counties of the state: Albany, Laramie, Carbon, Park & Teton Cos. Numerous stations of D.
falcatum were registered by the author on the Beartooth Plateau, from the montane to alpine
(Kosovich-Anderson 2011). Recently, the species was also reported from the Bighorn Mtns. (Lenz
100
2011). The occurrencies of D. falcatum in the E WRR are the first known in Fremont County. The
species was encountered on wet shaded surface of granite debris lining Fiddlers Creek and
seasonally dry outlet of unnamed subalpine lake (both along Rd 300), and unnamed subalpine lake /
pool near the border of Teton and Shoshone National Forests (along Union Pass Rd).

® 125. D. uncinatum Mitten [D. falcatum (Hedwig) Myrin var. uncinatum (Mitten) Lawton]
G3G5. A holarctic species (or a variety of Dichelyma falcatum!) distributed mainly in mountains of
Northern Hemisphere. It’s usually attached to stones in cold, rocky streams in high elevation areas;
it also occurs on stream banks.
“Dichelyma uncinatum has been distinguished from D. falcatum by the narrower leaves with the
costa long-excurrent. The examination of a large number of plants, especially specimens from the
Pacific Northwest, shows that these characters are not correlated. Plants are found with broad
leaves and the excurrent costa to 1 mm long. A plant may have some leaves with the costa
percurrent and other leaves with the costa long-excurrent. Sporophyte characters are also quite
variable. In the same collection the seta may extend beyond the perichaetium or be covered by it.
The operculum may be nearly as long as the urn or very much shorter. Because many specimens
are intermediate, D. uncinatum is made a variety and not a species” (Lawton 1971, p. 231).
This species (or variety?) is infrequent in Wyoming. It was previously known in the state from
Yellowstone National Park on E. Lawton’s collections of 1951 (Eckel 2013) and from Beartooth
Mtns. (Kosovich-Anderson 2011). I found several stations of D. uncinatum in the SE WRR. This is
the first record for Fremont Co.

is widely distributed all across Holarctic, except for arid regions; it grows on rocks, sticks, logs,
roots in slow- or fast-moving streams, ponds, ditches, swamps, and seasonally dry floodplains;
occurs from low to high elevations. In Wyoming and adjacent states, the species is rather frequent
(Lawton 1971; Flowers 1973; Elliott 1993; Weber & Wittmann, 2007; Lenz 2011; Eckel 2013;

131. Campylophyllum hispidulum (Bridel) Hedenäs G4G5. A species traditionally referred as
Campylium hispidulum, which represents a complex of recently recognized small species. It is a
small, easily overlooked “Campylium” growing on humus-rich soil or tree bases. “Campylophyllum
hispidulum and C. sommerfeltii are closely related, and some specimens are difficult to refer to
either species. However, C. hispidulum has a wider geographical distribution than C. sommerfeltii
in North America, but does, on the other hand, not occur in Europe, a clear indication that the two
103
are different taxa” (Hedenäs 2000b). According to some European bryophyte taxonomy
researchers, only Campylidium hispidulum (Bridel) Ochyra, sensu stricto, is a “real” North
American species. The taxonomy of North American Campylium s.l. complex will be discussed in
the Flora of North America, volume 28.
The species was reported from Albany and Weston Cos. (Eckel 2013). The WRR location is the
first known in Fremont Co.

® * 148. S. scorpioides (Hedwig) Limpricht G4G5. Widely distributed in the Arctic and in
northern part of boreal zone. Common in many areas in the north, and in the Arctic, rich or
intermediate habitats in fens, pools, lake shores or submerged in lakes; 0--3550 m. General
distribution includes North and South America, Eurasia and Australia. In North America reported
from Greenland, Canada (Alta., B.C., Nfld., Man., N.B., Nfld., N.W.T., Nunavut, N.S., Ont., Que.,
Yukon); U.S.A. (Alaska, Colo., Conn., Ind., Maine, Mich., Minn., Mont., Utah, Vt., Wis., Wyo.)
(Hedenäs 2008). In this portion of the Rocky Mountains, Scorpidium scorpioides is infrequent,
restricted to calcareous seeps and fens, typically found floating in pools in calcareous subalpine
fens. In Montana, it is a rare species restricted to calcareous seeps and fens, and included to the list
of species of conservation concern with status S2 (Elliott 1993; Montana Field Guide). It’s rare in
Wyoming, known from very few locations in Beartooth Mtns. (on collections of Elliott and the
author), Bighorn Mtns. (Lenz 2011) and Yellowstone National Park (Lemly & Cooper 2011). New
to Fremont Co.
S. scorpioides is “a large water moss with soft and pliant, densely foliate stems with short
pinnate branches. The plant is [brown or] black except for the apices of the leaves exposed above
the water level. The leaves are short, convex, and falcate-secund. The stems reach up to more than
a dm long” (Weber & Wittmann 2007, p.36). The apices of the leaves of S. scorpioides are curved
like a scorpion’s tail. Figs. 55-57.

G5. Circumboreal species distributed from the high Arctic (Spitzbergen) to Central Europe,
mountains of South Siberia, northern provinces of China, Japan, also in North America; in most of
the boreal zone it is a rare species (Ignatov & Ignatova 2004). It mainly occurs on moist soil in fens
and calcareous sites, from low to high altitudes. “It is inconspicuous and rarely collected, but
expected to be frequent in willow carrs and wet tundra” (Weber & Wittmann 2007, p. 98-99.). Until
recently, it’s been known in Wyoming from Big Horn, Sheridan, and Park Cos (KosovichAnderson 2011; Lenz 2011; Eckel 2013) and also in Albany Co (on unpublished author’s
collections from Sheep Mtns.). The SE WRR locations are the first known in Fremont Co.

*? 173. H. revolutum (Mitten) Lindberg G5. A circumpolar species, widely distributed in the
Northern Hemisphere, with bipolar distribution; occurs at sea level in the northern portion of its
range, but is most frequent at higher elevations (Ignatov & Ignatova 2004). Very common in
Wyoming and adjacent states; growing (mainly) on a thin layer of soil over shaded faces of rocks
of different origin (Porter 1937; Lawton 1971; Flowers 1973; Elliott 1993; Weber & Wittmann
2007; Eckel 2013; Kosovich-Anderson 2013a; unpublished author’s data). In Colorado (as well as
across all of this portion of the Rocky Mountains), it’s “probably the most abundant and
conspicuous pleurocarpous moss throughout the forested area, from the lower foothills up to the
alpine. Typically, it covers boulders with a smooth, shiny, green carpet of beautifully “braided
stems”, covering several square ft and visible from a great distance” (Weber & Wittmann 2007, p.
100). In the E WRR, it is a widely distributed species represented by two varieties -
