French Researchers Isolate Psilocybin and Psilocin From Spores

French researchers obtained crystalline psilocybin and very small amounts of psilocin from both the spores and sclerotia of Psilocybe mexicana.

1958

From the abstract: “From both sporophores and sclerotia of P. mexicana, the former cultured on natural media, the latter in vitro on artificial media, the authors obtained a crystalline material ‘psilocybin’, which had a strongly psychotropic effect on man, and also ‘psilocin’, in very small quantities.”
