SPECIES ATLAS · INOCYBE

Inocybe tricolor

Named by Kühner, 1955

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.

Kühner published Inocybe tricolor in 1955 in a supplement to the Bulletin de la Société des naturalistes d'Oyonnax. Index Fungorum records its typification as not determined. Krieglst. (as GBIF lists the author) later treated it as a variety of I. corydalina.

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 detected in a collection from Achensee, Tyrol (1982); muscarine not clearly detected

    Method: high-resolution TLC. Besl & Mack 1985, Z. Mykol. 51: 183-184 (full text, Zobodat, CC BY-ND)

  2. 2013

    Reported Listed among six psilocybin-producing Inocybe species; Table S1 cites Besl & Mack 1985 and Gartz 1986; listed 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, a TLC screen of a single 1982 collection, was found.

Records on file.

GBIF, the global biodiversity database, held 101 occurrence records under this name, 0 of them from Canada, when we checked on October 25, 2026. Records include unverified observations and old misidentifications, so counts show where people have recorded the name, not where it grows.
