Notes

Considered by some taxonomists to be a synonym or tropical variant of P. cubensis rather than a distinct species. Commonly encountered by travelers in Southeast Asia. Thai species are often consumed in local 'mushroom shakes.'

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.
