The occurrence of the psychotomimetic agent psilocybin in an Australian agaric, Psilocybe subaeruginosa

Australian Journal of Chemistry April 1, 1970 J. Picker, R. W. Rickards 18 citations

Psilocybin and its dephosphorylated derivative psilocin were first isolated from the hallucinogenic Mexican mushroom Psilocybe mexicana Heim. These compounds have since been found in many species of the genus Psilocybe from Mexico, North America, and Europe, as well as in Stropharia cubensis from Mexico, Thailand, and Cambodia, Conocybe cyanopus and amithiill from North America, a Copelandia from France, and Panaeolus sphinctrinus from Mexico (though this last occurrence is unconfirmed). Mono- and bis-demethyl analogues occur together with psilocybin in submerged cultures of Ps. baeocystis. However, not all Psilocybe species contain these metabolites; Ps. yungensis and atrobrunnea lack them.
