CAP 1-2(3)cm across, obtuse to broadly convex when young, with a somewhat incurved margin, sometimes with a rather pronounced umbo, sometimes with somewhat depressed disc; "fuscous" over disc, "drab" or paler toward margin, not fading appreciably; bald, "even or slightly wrinkled, appearing rather dry and velvety", hardly striate but margin frequently cracks or splits radially when old
FLESH thin, brittle, watery, if the cap surface is cut, drops of a colorless liquid ooze out
GILLS broadly adnate to arcuate-subdecurrent, close to crowded (26-35 reach stem), 2-3 tiers of subgills, narrow; pallid with edges sordid brown to fuliginous [soot-colored]; sometimes interveined, edge fringed under a hand lens from projecting cystidia
STEM 1.5-2.5(3)cm x 0.1-0.2cm, short, equal or the base slightly enlarged, brittle-cartilaginous; 'dark gray to blackish brown at first, becoming grayish brown to almost hyaline gray'; dull and pruinose at first, becoming more or less bald and polished when old; base with scattered mycelial hairs
