Similar species
Conocybe tenera is a small saprotrophic mushroom with a conic to convex cap which is smooth and orangish brown. It is up to 2.5 centimetres (1 in) wide[3] and is striate almost to the center. The stem is 3 to 9 cm (1+1⁄4 to 3+1⁄2 in) long, 1–4 mm thick, and is equal width for the whole length, sometimes with some swelling at the base.[2] It lacks an annulus (ring), is hollow and pruinose near the top.
The gills are adnexed and pale brown, darkening in age. The spore print is rusty brown.[3] The spores are yellowish brown, smooth and elliptical with a germ pore,[2] measuring 12 x 6 μm.
The species requires microscopy to identify. It resembles members of Galerina, Pholiotina, and Psathyrella, as well as Parasola conopilea.[3] The related C. filaris is poisonous.[2]
Distribution and habitat
Common in disturbed areas in North America,[3] it is widely distributed across the world.
