Originally described from Europe as Agaricus corrugis,[1] the species is considered non-toxic but lacking in flesh,[2] flavor and texture.

[3] 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.

[4] The cap is 1–4 cm wide, bell-shaped and translucent when young; it flattens and becomes opaque with age.

[2] The whitish stalk is 4–12 cm (1+5⁄8–4+3⁄4 in) tall and 1–3 mm wide.

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