Psathyrella piluliformis, commonly known as the clustered brittlestem,[2] is a species of agaric fungus in the family Psathyrellaceae.
Description
[edit]It produces fruit bodies (mushrooms) with broadly convex caps measuring 2–5 cm (3⁄4–2 inches) in diameter.[3] The caps are chestnut to reddish brown, the color fading with age and with dry weather.[3] Fragments of the partial veil may remain on the cap margin, and as a wispy band of hairs on the stipe.[3]
The closely spaced gills have an adnate attachment to the stipe.[3] They are initially tan until the spores mature, when the gills turn dark brown.[3] The stipe is 2–7 cm tall and 3–7 mm wide, white, smooth, hollow, and bulging at the base.[3] The spore print is dark brown, sometimes purplish.[4]
Similar species
[edit]Similar species include Psathyrella carbonicola, P. longipes, P. longistriata, P. multipedata, P. spadicea, and Parasola conopilus.[3][5]
Habitat and distribution
[edit]Fruiting occurs in clusters at the base of hardwood stumps.[3]
Uses
[edit]The species is considered edible but of low quality,[1][6] with fragile flesh and being difficult to identify.[5]
