Key Identification Feature

European highland dung habitat; Pyrenean distribution; consistent blueing confirms identity

⚠ Dangerous Lookalikes

Psilocybe semilanceata (grassland, no dung association, no umbo); Stropharia species (non-psychoactive, different ecology)

Notes

One of the few European dung-associated Psilocybe species outside of P. fimetaria. Found primarily in mountain pastures in the Pyrenean region. Rarely encountered and poorly known outside Spanish mycological literature.

Legal Status Warning Psilocybin-containing mushrooms are controlled substances in most jurisdictions. This guide is for educational purposes only. Wild foraging for psilocybin mushrooms may be illegal in your location. Never consume wild mushrooms without positive identification from an expert mycologist — misidentification can be fatal.
