With its streaked, gray-brown cap and its collybioid stature, Clitocybula lacerata looks like a small species of Megacollybia. However, the stem base of Clitocybula lacerata is not connected to white cords, its gills usually feature prominent cross-veins, and it differs microscopically (see below). Among other species of Clitocybula, it is distinguished by its comparatively large size, its tendency to grow gregariously or in loose (rather than dense) clusters, and microscopic details.
Ecology: Saprobic; growing alone, scattered, gregariously, or in loose clusters on the wood of spruces, birches, and oaks (but often attached to buried wood and appearing terrestrial); summer and fall; fairly widely distributed in North America.
Cap: 2-6 cm; convex with an inrolled margin, becoming more or less flat, with a shallow central depression and a wavy margin that is not lined but often splits radially; streaked; with appressed radiating fibers; moist; gray to gray-brown.
Gills: Broadly attached or beginning to run down the stem; distant or nearly so; with numerous cross-veins; white, sometimes discoloring grayish.
Stem: 1.5-5 cm long; up to 5 mm thick; more or less equal, or flared at the apex; bald; hollow; whitish to gray.
Flesh: Thin; white.
Odor and Taste: Not distinctive, or slightly unpleasant.
Chemical Reactions: KOH on cap surface negative.
Spore Print: White.
Microscopic Details: Spores 6-8 x 4.5-6 µ; ellipsoid; smooth; amyloid. Hymenial cystidia absent. Pileipellis a cutis of elements 3.5-7 µ wide, with clavate pileocystidia over the disc. Clamp connections present.
