Panaeolus fimicola is a widespread but seldom identified "little brown mushroom" which sometimes contains small amounts of the hallucinogen psilocybin. Panaeolis ater is a synonym.[1] The species is also referred to as the "turf mottlegill".[5]


  • Cap: (1)1.5— 3.5(4) cm, Campanulate then convex to plane, obtuse, dingy gray to blackish, often with reddish or hazel tones, hygrophanous, pallid grey to yellowish when dry, smooth, with a narrow brown marginal band, slightly striate at the margin when moist. Flesh thin and grayish.
  • Gills: Adnate, close to crowded, at first gray-olivacous, becoming mottled and darkening to black with age, edges remaining whitish.
  • Spores: Blackish gray.
  • Stipe: (4)6 — 8(10) cm x 1 — 2(3) mm, equal, slender, slightly enlarging at the base, hollow, fragile, dingy white to clay, becoming brownish towards the base in age, smooth, white-pruinose at the apex, obsoletely slightly silky-striate, ring absent. Flesh is dirty ochraceous-buff; fragile.
  • Taste: Not distinctive.
  • Odor: Not distinctive.
  • Microscopic features: Spores 10.8 — 14.2 X 6.9—9.5, ellipsoid or lemon shaped, basidia 4 spored. Gill edge cystidia fusiform, typically with long necks, gill face cystidia absent.

Habitat and formation[edit]

Panaeolus fimicola can be found growing solitary to scattered in soil or dung, fertilized lawns and other grassy places, late spring to mid-fall. It is widespread and common across the Americas, as well as Europe and Africa. It has also been found in Turkey.[6]
