title: Baeocystin in psilocybe, conocybe and panaeolus.
abstract: Sixty collections of ten species referred to three families of the Agaricales have been analyzed for the presence of baeocystin by thin-layer chromatography. Baeocystin was detected in collections of Psilocybe, Conocybe, and Panaeolus from the U.S.A., Canada, Mexico, and Peru. Laboratory cultivated fruitbodies of Psilocybe cubensis, P. semilanceata, and P. cyanescens were also studied. Intra-species variation in the presence of decay rate of baeocystin, psilocybin and psilocin are discussed in terms of age and storage factors. In addition, evidence is presented to support the presence of 4-hydroxytryptamine in collections of P. baeocystis and P. cyanescens. The possible significance of baeocystin and 4-hydroxytryptamine in the biosynthesis of psilocybin in these organisms is discussed.
