Psathyrella corrugis, is the type species of the basidiomycete fungus genus Psathyrella and family Psathyrellaceae. Originally described from Europe as Agaricus corrugis,[1] it is common in North America and is regarded as inedible.

Nomenclature

The lectotype of Psathyrella is Psathyrella gracilis, however P. corrugis was published in 1794, 27 years before P. gracilis was first published, making P. corrugis the correct name. The name given here is according to Index Fungorum.[2]

Description

The cap is 1–4 centimetres (1⁄2–1+1⁄2 in) wide, bell-shaped and translucent when young; it flattens and becomes opaque with age.[3] The gills are slightly reddish.[4] The whitish stalk is 4–12 cm (1+5⁄8–4+3⁄4 in) tall and 1–3 mm wide.[3] The spores are purple-brown, elliptical, and smooth.[3] The spore print is dark brown to black, sometimes with hints of purple.[5]

The species is considered non-toxic but lacking in flesh,[4] flavor and texture. It is inedible.[6]

The species sometimes fruits with Tubaria furfuracea. A similar species is Candolleomyces candolleanus.[3] Microscopy may be needed to distinguish P. corrugis from similar species.[5]

Habitat and distribution

It can be found growing around areas of dead wood and grass throughout North America.[4][5]
