Psilocybe strictipes is a psilocybin mushroom which grows on grassy meadows and lawns; It is found throughout the cool temperate and subarctic regions of the Northern Hemisphere and it is most common in Europe, and the Pacific Northwest. It is closely related to Psilocybe semilanceata and Psilocybe pelliculosa. Psilocybe strictipes is commonly confused with Psilocybe semilanceata and can be differentiated by its lack of a papilla and a convex to subumbonate cap.



  • Cap: 5 to 30 mm across, conic to campanulate to convex, smooth, translucent-striate near the margin, often with a low umbo. Walnut brown to dark rusty brown, with a smooth surface and a separable gelatinous pellicle. Hygrophanous, fading to buff as it dries. The flesh sometimes stains blue where damaged.
  • Gills: Cream colored when young, dark purple brown when mature, adnate attachment.
  • Spores: Dark purple brown, suboblong, 11 x 6 micrometers.
  • Stipe: White to ocher, equal, tough and cartilaginous with fibrillose patches, 4 to 10 cm long, .25 cm thick. The partial veil is thin, cortinate, and does not usually leave any remnants on the stipe.
  • Taste: Farinaceous.
  • Odor: Farinaceous.
  • Microscopic features: Pleurocystidia absent, cheilocystidia 21-45 by 7-10 micrometers, lageniform with a neck.

Habitat and distribution

Fruits late summer to fall in Chile, England, France, Germany, Holland, Slovakia, Siberia, Sweden, and the Pacific Northwest.

Found in lawns and grassy fields, never growing directly from dung.
