Notes

One of the first Psilocybe species documented spreading into urban environments via wood chip landscaping. Psilocybin content is low (0.2-0.6%) compared to other cultivated species. Named after mycologist Daniel Stuntz.

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.
