SPECIES ATLAS · INOCYBE

Inocybe erinaceomorpha

Named by Stangl & J. Veselský, 1979

Psilocybin record: reported (one analysis)

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.

Stangl and Veselský described Inocybe erinaceomorpha in 1979 in Česká Mykologie 33: 72. Kuyper treated it as a variety of I. corydalina, the name used in the 1985 chemistry paper; Index Fungorum and GBIF accept it as a species.

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 demonstrated for the first time (as I. corydalina var. erinaceomorpha), with no muscarine

    Method: TLC in three systems, confirmed by HPLC. Stijve, Klán & Kuyper 1985, Persoonia 12(4): 469-473 (Naturalis repository, full text)

  2. 2013

    Reported Listed among the psilocybin-producing Inocybe species

    Method: listed in Kosentka et al. 2013 without its own analysis. Kosentka et al. 2013, PLoS One 8: e64646, with Table S1 (full text PMC3662758)

What the record doesn’t show: One analysis of herbarium material from 1985; psilocybin breaks down in stored specimens, as the authors note.

Records on file.

GBIF, the global biodiversity database, held 370 occurrence records under this name, 2 of them from Canada, when we checked on October 25, 2026. GBIF lists 2 occurrence records from Canada under this name (checked 2026-10-25); the records are not verified identifications. Records include unverified observations and old misidentifications, so counts show where people have recorded the name, not where it grows.
