Baeocystin is a psilocybin mushroom alkaloid and analog of psilocybin. It is found as a minor compound in most psilocybin mushrooms together with psilocybin, norbaeocystin, and psilocin. Baeocystin is a N-demethylated derivative of psilocybin, and a phosphorylated derivative of 4-HO-NMT (4-hydroxy-N-methyltryptamine).

Baeocystin was first isolated from the mushroom Psilocybe baeocystis,[1] and later from P. semilanceata,[2] Panaeolus renenosus, Panaeolus subbalteatus, and Copelandia chlorocystis.[3] It was first synthesized by Troxler et al. (1959).[4]

Little information exists with regard to human pharmacology, but in the book Magic Mushrooms Around the World, author Jochen Gartz reports being aware of a study in which "10 mg of baeocystin were found to be about as psychoactive as a similar amount of psilocybin."[citation needed] Gartz also reported in a research paper that a self-administered assay of 4 mg of baeocystin caused "a gentle hallucinogenic experience".[5]
