Alsia californica (p.311)
Anacolia menziesii (p.194). Tufts of branched, yellow green stems with dense reddish rhizoids. Roadbanks and seasonally
moist rock walls.
Bestia longipes (p. 12). Like Dendroalsia but on sandstone boulders at JRBP in shaded riparian drainages, and capsules
are usually lacking. See comments for Dendroalsia. Bestia often grows near by Pterogonium but tends to occupy moister
and more shaded parts of same boulder face.
Brachythecium albicans (p.259). Pale yellow green mats of creeping stems, more or less julaceous. Soil, leaf litter, and thin
soil over shaded rock. This moss can be confused at arms length with both Homalothecium arenarium and Scleropodium
touretii, and all are members of the same family.
Bryum argentium (p.166). Whitish or silvery green tufts of erect shoots. Soil rock or gravel esp disturded sites.
Dendroalsia abietina (p.302). The dry plants curve down in a distinctive manner when dry (the branches curve and fold
downward concealing the capsules -- p.9), and when wet they appear flat like a feather. Paraphylla leaf-like structures cloak
the branches under the true leaves are common, but are lacking in both Bestia and Pterogonium.
Didymodon vinealis (p.127). Common. Turfs or cushions of erect, sparsely branched stems. Lvs oval-lanceolate or more
commonly long lanceolate, twisted when dry; generally with a reddish cast. On soil or rock. Often on boulders in serpentine.
Fissidens crispus (p.84; key p.317 "lvs in 2, 3 or 5 ranks"). Seasonally moist clayey soils along trails and roadbanks. One of
only two genera likely to be found at JRBP with 2-ranked leaves. The second Bryolawtonia hasn't yet been found. JS refers
to the Iris-like lvs but this is confusing and sometimes only apparent for lowest leaves.
Grimmia V-shaped lvs in cross-section; lf tip with a long hyaline hair point.
Homalothecium spp. (p.263). Dirty yellow-green shag-carpet when dry. Creeping (irregularly branched) stems flat to
substrate at edges of its mossy mass.
H. arenarium on soil and litter.
H. nuttallii on logs, tree trunks and boulders.
H. pinnatifidum on tree trunks
Leucolepsis acanthoneura (p.177). Little palm trees (dendroid) with white (actually hyaline, i.e., transparent) scales on
shoots below leaves.
Pterogonium gracile. (p.305). Birds-foot appearance when dry. See comments for Bestia.
Scleropodium obtusifolium (p.274). Mats or tufts of irregularly branched stems on boulders and rock wallls of streams or
intermittent streamlets; sometimes on exposed tree roots. On serpentine boulders along and in SF Creek, Trail 1. Has the
gestalt when hydrated of Homalothecium but the stems are julaceous (lvs crowded and appressed against the stem and
overlapping each other.
Scleropodium touretii (p. 275). Common on soil and rock away from streams (e.g., along Trail 5 bank). Less julaceous and
lighter green color than above.
Liverworts
Hornworts
