Common Name: none
Synonyms: Pseudocoprinus disseminatus (Fr.) Kuhner, Coprinus disseminatus (Pers.: Fries) S.F. Gray
Cap 0.5-1.5 cm broad, narrowly to broadly parabolic, expanding sometimes to convex or bell-shaped; surface dry, minutely hairy but usually glabrous at maturity, striate-furrowed to near the disc, the margin striate-sulcate; color: pale yellow-brown to tawny-brown at the disc, shading to a lighter margin, becoming pale grey-brown in age except for the disc; flesh thin, soft, fragile; odor mild.
Gills adnate, subdistant, broad, pallid, then grey, finally blackish, but not deliquescing.
Stipe 1.5-3.0 cm tall, 1-2 mm thick, equal, fragile, hollow, straight or slightly bent from the base; surface minutely hairy, pallid; veil absent.
Spores 7-10 x 4-5.5 µm, elliptical smooth, with an apical pore; spore print blackish.
Gregarious or in troops on woody debris or from buried wood; fruiting spring and fall.
Edible, but insignificant.
Often forming large troops on woody debris, this diminutive Coprinellus is characterized by a broadly parabolic to convex, pale greyish-brown, striate cap with a yellowish-brown disc. Since the gills of this species do not deliquesce, thus some authors have placed it in the genus Pseudocoprinus. Recent molecular studies suggest however that it properly belongs in Coprinellus.
