the Celestial

Inocybe coelestium is a fragile looking magic mushroom, and one of the rare members of the large Inocybe genus that are psychoactive.

Because the large Inocybe genus of 1400 species includes edible, psychoactive and poisonous mushrooms mixed, it has the reputation of being a “mycological minefield”, it is therefore advised to would-be psychonauts to refrain from ingesting these fungi from the wild.

The epithet “coelestium” refers to the celestial inhabitants of the highest mountain of Greece: the Gods of Mount Olympus.

Even though analyses show this fungi to be relatively weakly active, it probably still has enough neurotropic indoles to make one feel on top of the highest of mountains.

Inocybe coelestium is found in Europe and other temperate areas.
It was first documented by mycologist Thomas Kuyper in 1985 and is believed to be much more widely distributed than reported so far.

The fact that this inconspicuous mushroom is named in honour of the heavenly home of the Supreme Beings can only echo the belief of its transcendental psilocybian powers.

Spore print: clay brown Microscopic features: 7.5-10 by 4-5 µ Odor: disagreeable, some say soapy smelling, others spermatic.


MILD < 0.25% MODERATE 0.25% - 0.75% (Stijve and Kuyper 1985) 0.035% psilocybin, no psilocin, 0.025% baeocystin. Most Inocybes have not been tested for neither their edibility, psilocybin activity or toxicity. Of those tested, none have been proven to contain both psilocybin and muscarine (the toxic substance). Psilocybe authority Stamet wonders if that cohabitation of compounds within one specie is possible and if it will eventually be brought to light.

Habitat Origin

Widely distributed in Europe (Austria and Germany). Grows under deciduous trees, in calcareous soils, in August through October.


Said to be relatively rare and considered a type of oddity in the wide collection of psychedelic fungi. Psilocybe authority Stamet doesn't advise its consumption by the would-be psychonaut. In the wide collection of psychedelic fungi, and the minefield that this genus represents, Psilocybe authority Stamet doesn't advise the picking and consumption of Inocybe from the wild.
