Notes

Found once in the wild, in 1977, near Tampa, Florida by mycologist Steven Pollock. The specimen was cultivated and distributed. All existing tampenensis cultures descend from that one collection — a remarkable bottleneck in the genealogy of a species.

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.
