This saprobic caerulescent Psilocybe from Germany was first described in 2015 by Jochen Gartz and Georg Wiedemann. The novel psychoactive specie showed a unique combination of features related to stipes and pileus with a particular joint‐like thickening characteristics. Nonetheless, even if P. germanica has its very own morphological subtleties, recent DNA sequencing has revealed it to be a synonym of Psilocybe serbica. It has a relatively high potency similar to Psilocybe semilanceata.
Chemical analyses revealed the presence of significant amounts of psilocybin and baeocystin, which seems to make this specie the first described species derived from wood chips that contains significant amounts of baeocystin in the absence of psilocin.
Because this specie’s flesh readily turns blue when bruised yet never contains detectable amounts of psilocin, the theory that the bluing phenomenon occurs because of the presence of psilocin is questioned.
This autumnal and lignicolous “new kid on the block”, though not as known as other psychedelic Psilocybes, sure has an enigmatic uniqueness to it and should be kept an eye on. Though the specie was only reported from Germany, it is suggested that the modern use of mulch in parks and gardens might remarkably widen its area of distribution; a phenomenon which has probably already started and was observed with P.cyanescens.
