Notes

Potency is geographically variable — some North American collections are active, others are not. Bitter taste makes consumption unpleasant. Not a reliable psychedelic source.

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.
