Cap: 1-2 cm., convex, gray-brown becoming darker brown, viscid or dry, striate margin smooth, may have very fine hairs along margin, thin.

Gills: Gray-brown to dark purple, turning to brown in age. Adnate with edges white and distant.

Stem: 2-6 cm. long, 1-3 mm. thick, straight and equal. Yellowish-brown, dry and silky, smooth, while base is enlarged with mycelium.

Spores: 11-5 x 6.5-9 .

Sporeprint: Chocolate to purple-brown.

Habitat: Solitary to gregarious, in manure of four-legged ruminants. Also sometimes in horse manure as well as other livestock. Sometimes in lawns

Distribution: Cosmopolitan, widely distributed in the west, but occurs throughout much of the world.

Season: Spring to early winter. After rainfall.

Dosage: No dosage is required (non-active).

Comment: This species is named for the manure it grows from implying it is of a coprophilous nature (dung-inhabiting). It is not an active species although numerous field guides list it as being possbibly hallucinogenic and/or toxic. This was originally based on the fact it grew in manure and because of it's relationship to other active Psilocybe species in the Genus Psilocybe. While over 200 known species of fungi are psilocybian, there are currently about 80 species of Psilocybe that contain no psilocine and/or psilocybine or other related active tryptamine alkaloids. Serotonine, tryptophan and urea are present in this species.
