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.[4]

Description

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

It can be found growing around areas of dead wood.[2]

The species sometimes fruits with Tubaria furfuracea. A similar species is Psathyrella candolleana.[5]
