Species Information
Summary:
Features include 1) a hygrophanous, brown to gray-brown, moist, bald, striate cap, 2) pallid gills, 3) a polished stem that is whitish to pallid or cap-colored, 4) growth on soil among liverworts and mosses, 5) a white spore deposit, and 6) microscopic characters. Bigelow(4) gives Mycena cineraria A.H. Sm. as a synonym, and Smith''s description of the WA type is used below as well.
Gills:
broadly adnate to short-decurrent, close or subdistant, moderately broad to broad, up to 0.4cm broad; white or becoming dingy tan or avellaneous when old, (Bigelow), broadly and bluntly adnate, soon short-decurrent, close to subdistant, 16-20 reach stem, broad, 1-2 tiers of subgills; "tilleul buff" (pallid); edges faintly fimbriate [fringed] under lens, (Smith)
Stem:
1-3(6)cm x 0.1-0.3cm at top, equal, solid; translucent, colored as cap or pallid; bald, (Bigelow), 3-4cm x 0.1-0.15cm, tubular, straight; whitish to pallid; polished, "the base with a thin covering of white mycelium", (Smith)
Odor:
none (Bigelow), rancid, mealy, (Buczacki)
Taste:
none (Bigelow), indistinct or slightly floury (Buczacki)
Microscopic spores:
spores 5.5-7 x 4-4.5 microns on 4-spored basidia, up to 11 x 7 microns from 2-spored basidia, elliptic, verruculose; basidia 19-27 x 4-8 microns, usually 4-spored but sometimes also 2-spored; pleurocystidia of same type as cheilocystidia but less numerous and very scattered along gill faces, cheilocystidia numerous on some gills but rather scattered on others, 33-62(100) microns long, 5.5-11 microns wide, protruding 15-47 microns beyond hymenium, subcylindric or rather fusoid-ventricose, apices obtuse, rounded, or subcapitate, colorless, smooth, walls thin; cap cutis brownish in KOH, pigment very finely encrusted on hyphal walls, hyphae 1.5-7 microns wide, cylindric or slightly inflated; clamp connections present, (Bigelow), spores 6-7 x 4-4.5 microns, broadly elliptic, inamyloid, smooth but appearing echinulate (spiny) under oil immersion because of pores in spore wall; basidia 4-spored; pleurocystidia and cheilocystidia scattered to fairly abundant, 44-66 x 9-12 microns, obtuse, subcylindric, the outlines usually a little irregular; clamp connections present, (Smith)
Spore deposit:
white (Bigelow)
Notes:
Collections were examined from WA, OR, ID, MB, NWT, AK, CO, MI, WY, Norway, Switzerland, and the United Kingdom, (Bigelow(4)). There is a BC collection at the University of British Columbia.

Gamundia leucophylla (Gillet) Raithl. is recorded in Redhead(5) on the list of rare or notable species of macrofungi of British Columbia, but specifics on the records are lacking to determine whether this represents Gamundia striatula (Kuehner) Raithelh. (it has been listed as a synonym of the latter), or Gamundia leucophylla (Gillet) Bigelow. Fayodia bisphaerigera lacks the large cystidia, (Smith).Habitat
gregarious or subcespitose [more or less in tufts]; on or near Peltigera and other lichens, in sandy soil or moss; in the open or under spruce; June to October, (Bigelow), scattered on wet soil among liverworts and mosses, September, (Smith), fall to winter (Buczacki), summer, fall, winter
