About Psathyrella longistriata (Murrill) A.H.Sm.
Psathyrella longistriata has a cap that measures 1.7 to 5 centimeters in diameter. Initially rounded and conical, the cap shape becomes campanulate as it matures. Fragments of partial veil tissue sometimes hang from the cap margin. When moist, the cap margin is striated, and these striations typically develop as the mushroom ages. Young caps have a fibrillose surface texture. The stipe of this species is 3 to 9 centimeters long and 8 to 15 millimeters wide. It bears an annulus, which has striations on its upper surface. The gills are grayish buff when young, and darken to a browner color as the mushroom ages. The spore print of Psathyrella longistriata is dark purplish brown. This mushroom occurs in low-elevation forests, growing on rotting wood or within leaf litter. It mostly produces fruiting bodies during the fall, and fruits occasionally in winter and spring.
