✦ Synopsis

limited free amino acid pool in P. cyanescens is responsible for the failure of the fungus to accumulate psilocybin in saprophytic cultures. However, the results do suggest that the isolate of P. cyanexens is less responsive to phosphate nutrients and has narrower metabolic tolerance than P. cubensis P. camfiaanulatus appeared to be the most metabolically responsive of the species tested. It grew well under the saprophytic conditions and appeared to have an adequate soluble nitrogen pool. These observations suggest the improbability of a limited supply of common amino acids as the basic factor behind the lack of serotonin production in saprophytic cultures. Some key factor controlling the formation or function of tryptophan hydroxylase is probably responsible for the different metabolic capabilities of carpophores and vegetative mycelium of this basidiomycete.
