Earlier findings published in 1961 [107] suggested that psilocybin is finally been synthesize from tryptophan. The hypothesis was based on the results obtained from still cultures of Psilocybe semperviva. Subsequent studies on the subject carried out using Psilocybe cubensis under submerged cultural condition also supported this hypothesis that psilocybin may biosynthetically derive from tryptophan and tryptamine [108]. More details were then published to clarify the sequence of events which leads from tryptophan to psilocybin by incorporating and C " - labeled hypothetical intermediates (such as DL-Tryptophan- H, Tryptamine- V,... 

Ergotamine (36) and ergometrine (19) are partially isomerised on C-8 (but not hydroxylated) to ergotaminine and ergometrinine by Psilocybe semperviva and partially decomposed (Brack et al., 1962).
