Rarely discussed outside European mycology. Scandinavian records more common than British. Potency moderate. Sometimes collected alongside Panaeolus species in manured grass areas.

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.
