About Psathyrella corrugis (Pers.) Konrad & Maubl.
Psathyrella corrugis (Pers.) Konrad & Maubl. has a cap 1–4 centimetres (1⁄2–1+1⁄2 inches) wide. When young, the cap is bell-shaped and translucent; it flattens and becomes opaque as it ages. Its gills are slightly reddish. The whitish stalk measures 4–12 cm (1+5⁄8–4+3⁄4 in) tall and 1–3 mm wide. Its spores are purple-brown, elliptical, and smooth. The spore print is dark brown to black, sometimes with purple hints. This species is non-toxic, but it has very little flesh, and is poor in both flavor and texture. It is classified as inedible. It can be found growing near dead wood and in grass across North America. It sometimes produces fruiting bodies alongside Tubaria furfuracea.
