syn. Psilocybe serbica

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.

Visual Description

• Cap: 1–4 cm broad. Always broadly umbonate, rarely flattening in age with a persistent broad umbo; no traces of a veil at any stages. Cap is hygrophanous, coloration is deep brown when moist, bluish hue visible on cap when young. Margin not wavy, not striate, not translucent when moist, fading to whitish in drying. Coloration has a gray‐bluish hue on the umbo when young. Flesh has strong blueing, particularly after rains, during freezing and bruising. • Gills: At first brownish then dark purple‐brown, closely set, alternating adnexed to adnate. • Stem: 5-9 cm long by 0.3-0.7 cm thick. Usually enlarged near cap. Surface is dry, white, not very hard, not flexuous, always curved, often multiple times. Equal sometimes slightly thicker at base and apex. No traces of a veil, no fine mycelia on it. Flesh easily staining deep blue when touched, first touch sometimes green discoloring until a very fast‐moving to deep blue; rhizomorphs on the base, strongly attached to wood substrate. • Microscopic features: 9–12 × 5.5–7.5 µm • Taste and odor: odour described as pleasantly aromatic.

Potency Description

Psilocybe germanica showed similar alkaloid levels to what is known about Psilocybe semilanceata. Chemical analyses revealed the presence of significant amounts of psilocybin and baeocystin psilocin was not detected 1.12% psilocybin, no psilocin, 0.30% baeocystin 0.90% psilocybin, no psilocin, 0.11% baeocystin 0.66% psilocybin, no psilocin, 0.21% baeocystin

Habitat Origin

To date only known from Germany. Grows gregariously in soils enriched with deciduous wood‐debris, deciduous wood chips from various plants, on bark. Observed growing is from September to December. Until now, only been observed to grow in parks. As observed with P. cyanescens, it is expected that Psilocybe germanica might be found to achieve a remarkably wide area of distribution in the future given the modern use of mulch in parks and gardens.
