Notes

Included because it is one of the most commonly encountered Panaeolus species and a frequent source of misidentification. It grows in the same habitats as psychoactive Panaeolus species but does not contain psilocybin. Always verify blueing reaction before assuming psychoactive content.

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.
