Notes

A commonly encountered tropical dung mushroom often confused with the psychoactive Panaeolus cyanescens. Antillarum does not contain significant psilocybin and does not blue when cut. Always confirm blueing before assuming psychoactive content in any Panaeolus 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.
