SPECIES ATLAS · INOCYBE

Inocybe coelestium

Named by Kuyper, 1985

Psilocybin record: reported (one or older reports)

A history of a name and a chemistry record, not an identification guide. No name, picture or description can show that a wild mushroom is safe, and poisonous mushrooms are mistaken for magic mushrooms. If someone may have eaten a wild mushroom, call a poison centre without waiting for symptoms: 1-844-POISON-X in most of Canada, 1-800-463-5060 in Quebec. Call 911 if they’re unconscious, not breathing or having a seizure.

How it was named.

Th. W. Kuyper described Inocybe coelestium in 1985 in Persoonia, from a collection he made near Augsburg in 1982, as a companion to a chemistry paper in the same issue. He named it after the inhabitants of Olympus, the gods, 'referring to its hallucinogenic properties'.

Named
Kuyper, 1985
Type specimen
Holotype Th. W. Kuyper 2088, 3 August 1982, Federal Republic of Germany, Bavaria, Augsburg, Haunstetterwald (L). (Kuyper 1985, Studies in Inocybe II, Persoonia 12: 479-482 (full text, archive.org, CC BY))
The pin marks the type locality at the level of detail the record gives: one historical collection, not a range or a place to look. Land outlines: Natural Earth.

The psilocybin record.

Every analysis we could verify, oldest first, including results that found nothing. No amounts are given: they vary between collections and this is not a potency guide.

  1. 1985

    Reported Psilocybin and baeocystin found in a 1982 German collection (first report for this taxon); muscarine absent

    Method: TLC in three systems, confirmed by HPLC. Stijve, Klán & Kuyper 1985, Persoonia 12: 469-473 (full text, archive.org, CC BY)

  2. 2013

    Reported Listed among six psilocybin-producing Inocybe species in a literature review; listed in Kosentka et al. 2013 without its own analysis

    Method: review (no analysis). Kosentka et al. 2013, PLoS One 8: e64646, with its Table S1 (full text, PMC3662758)

What the record doesn’t show: Only one chemical analysis (of herbarium material, 1985) was found.

Records on file.

GBIF, the global biodiversity database, held 32 occurrence records under this name, 3 of them from Canada, when we checked on October 25, 2026. GBIF held three Canadian occurrence records on 25 October 2026, although Kosentka et al. (2013) describe the psilocybin-producing Inocybe as apparently endemic to Europe. Records include unverified observations and old misidentifications, so counts show where people have recorded the name, not where it grows.
