AI-generated description

Psathyrella atrospora is a small to medium-sized fungus with a bell-shaped cap that ranges in color from dark brown to black, often with a lighter brown or grayish-brown center. The gills are crowded and attached to the stem, which is typically slender and hairy. In East and Central Texas, Psathyrella atrospora has been found growing in clusters on rich soil, rotten wood, and other organic matter, particularly in wooded areas and along streams. It fruits from spring to fall, with peak activity during the summer months. The fungus is considered inedible due to its small size and potential for confusion with other species.
