Psathyrella piluliformis

Psathyrella piluliformis is a species of agaric fungus in the family Psathyrellaceae. It produces fruit bodies (mushrooms) with broadly convex caps measuring 2–5 cm (34–2 inches) in diameter.[2] The caps are chestnut to reddish brown, the color fading with age and with dry weather.[2] The closely spaced gills have an adnate attachment to the stipe.[2] They are initially tan until the spores mature, when the gills turn dark brown.[2] Fragments of the partial veil may remain on the cap margin, and as a wispy band of hairs on the stipe.[2] The stipe is 2–7 cm tall and 3–7 mm wide, white, smooth, hollow, and bulging at the base.[2] Fruiting occurs in clusters at the base of hardwood stumps.[2]
