P. aerugineomaculans

Psilocybe subaeruginascens aka P. aerugineomaculans is a species of psilocybin mushroom in the Hymenogastraceae family. It is a close relative to hallucinogenic species Psilocybe stuntzii, P. subfimetaria, and Psilocybe ovoideocystidiata. Its epithet contains the Latin root “aeru- “ meaning “blue-green” which probably refers to its prominent bluing.
Because it shares similarities with the epithet of Inocybe aeruginascens, one wonders if it contains the rare compound aeruginascin. Aeruginascin is an analog to psilocybin and is closely related to the frog skin toxin bufotenine (5-HTQ), a potent 5-HT3 receptor agonist. This compound, identified by chemist and mycologist Jochen Gartz in the eighties, is believed to be the equivalent of what CBD is to THC.


Visual Description

• Cap: 1-6 cm broad. Conic to campanulate, to broadly campanulate with no umbo, to finally broadly convex or plane, lifting in age. Margin translucent striates, Coloration orangish brown to olive brown, to greenish brown, cap is highly hygrophanous, fading to dull yellow orange, to straw in drying. Flesh bruising bluish. • Gills: Attachment broadly adnate to adnexed, sometimes decurrent. Placement crowded. Color grayish brown to yellowish brown, dark brown, and often slightly mottled t maturity. Bruising bluish. • Stem: 30-60 mm long by 1.5-3 mm thick. Equal, slightly enlarged at rhizomorphic base. Coloration whitish, or similar to cap, soon bruising bluish. Partial veil annulus persistently present, well developed and soon bruising bluish and turning purplish brown with spore drop. • Spore print: dark purplish brown. • Microscopic features: 7.7-12 by 6.6-8.5 µ. • Taste and odor: farinaceous.

Potency Description

Between 0.25% - 0.75% psilocybin. Moderate

Habitat Origin

Found growing from April to July in Southern Japan and subtropical Java, Indonesia. Probably distributed between these two areas. Also reported fruiting in February and March in Kwazulu-Natal South Africa. Grows gregariously and in clusters in wood chips, humus, woody debris and gardens, in metropolitan areas, or along trails and roads in deciduous forests. It is occasionally found in dung.

Strain Effects

The Japanese refer to magic mushrooms in various ways such as “maitake” (dancing mushroom), “waraitake” (laughing mushroom), “o-waraitake” (big laughing mushroom), “odoritake” (jumping mushroom) or “shibiretake” (numbing mushroom). We can only speculate it has similar psychotronic effects as other moderately active psilocybin species. Thus, effects would include euphoria, visual stimulation with slight tracing effects and at higher doses hallucinations, impulses of energy, dilated pupils, enhanced heartbeat, occasional nausea, and a numbing physical effect.
