Summary:
Features include small size, a white pendant cap, a smooth white spore-bearing surface that may become vein-like with forked gill-like folds, a short or absent stem, growth on moss, and nearly round, smooth, inamyloid spores. The description is derived from Redhead(7).
Collections of Rimbachia bryophila were examined from BC, WA, OR, CA, and MI, (Redhead).
Cap:
0.1-0.7cm across, pendant, conchate to conical to cup-shaped, mostly bilaterally symmetric, margin incurved, fragile overall; white; dry, bald near margins, sometimes slightly villose near point of attachment
Gills:
smooth in very young fruitbodies, soon becoming cantharelloid [vein-like] and usually forming forked gill-like folds in larger fruitbodies; colored as cap
Stem:
absent or replaced by a short pseudostem
Odor:
not recorded
Microscopic spores:
spores 5-7 x 4.5-7 microns, nearly round to very broadly pip-shaped with very prominent apiculus, smooth, non-amyloid, colorless, with thin to pronounced walls; basidia 4-spored, 19-25 x 6-9 microns, clavate, clamped; pleurocystidia and cheilocystidia none; tramal hyphae 3-7 microns wide, "compactly to loosely subparallel, slightly interwoven", smooth, thin-walled, colorless, nonamyloid, clamped; pellicular hyphae 3-5 microns wide, "loosely arranged and occasionally projecting, a few ends near the margins with sparse diverticulae or irregularly formed short branches"
Spore deposit:
[presumably whitish]
