Stropharia shitty (Stropharia coprophila)


A hat with a diameter of 6 - 25 mm, initially hemispherical, sometimes with a small depression, becomes convex with age. The edge is first tucked inward, then gradually unfolds and becomes flat, in young mushrooms with remnants of a private veil in the form of white scales and an uneven white border. Coloring from light yellowish brown to dark reddish brown, lighter and faded with age. The surface is hygrophane, dry or sticky, shiny in wet weather, in young mushrooms it is radially radiant due to translucent plates. The flesh is thin, the same color as the cap; if damaged, the color does not change.

The stem is 25 - 75 mm long and about 3 mm in diameter, straight or slightly curved at the base, fibrous, in young mushrooms it is often covered with whitish scales, occasionally with remnants of a private veil in the ring zone, but more often without them. Coloring from whitish to yellow-brown.

The plates are adherent, relatively wide, not very frequent, gray-brown with a white margin, with age they become dark red-brown up to almost black.

The spore powder is purple-brown, the spores are smooth, ellipsoidal, 11-14 x 7-9 µm.


Saprotroph. It usually grows on manure (hence the name), singly or in groups, is quite rare (less often than the similar Psilocybe semilanceata). The period of active growth after rains, from mid-August to the onset of cold weather, in mild climates until mid-December.

Unlike many members of the genus Psilocybe, shitty stropharia does not turn blue when damaged.

Usually this mushroom is confused with hemispherical stropharia (Stropharia semiglobata), which also grows on manure, but differs in a mucous stalk, a more yellowish coloration and the absence - even in young mushrooms - of radial banding of the cap edge (i.e., the plates never shine through).

Representatives of the genus Panaeolus have a dry cap and spotted plates.


No data on edibility.


According to some sources, the mushroom is not hallucinogenic (neither psilocin nor psilocybin was found in it).
