A small, densely clustered wood-rotting mushroom with a grayish-brown, radially streaked cap that has a central depression, white gills and a slender whitish stem. It grows on dead wood of conifers and hardwoods, especially birch. Its weakly amyloid spores help separate it from similar small clustered mushrooms.
Cap: 1.5-3 cm, convex becoming flat with a central depression, bald with radiating fibers, pale grayish brown at the center to grayish buff at the margin, which often splits with age. Gills: white, close, broadly attached or slightly decurrent. Stem: 3-6 cm long, 2-3 mm thick, whitish above, brownish below, hollow. Flesh: thin, watery whitish. Odor and taste: not distinctive. Spore print: white. Microscopic: spores broadly ellipsoid, smooth, weakly to moderately amyloid, 4-7 x 3.5-5 µm.
