SPECIES ATLAS · GALERINA

Galerina steglichii

Named by Besl, 1993

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.

Helmut Besl described Galerina steglichii in 1993 in the Zeitschrift für Mykologie, from mushrooms that appeared in a greenhouse at the University of Regensburg; he suspected the site was not its natural home. He named it for the 60th birthday of the chemist Wolfgang Steglich, who studied the compounds of fungi.

Named
Besl, 1993
Type specimen
A greenhouse of the University of Regensburg (Botanical Institute), Germany, early 1993; holotype coll. 3/93 in herbarium REG. (Besl 1993, Z. Mykol. 59: 215-218 (full text, Zobodat, CC BY-ND))
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. 1993

    Reported Baeocystin, psilocybin and psilocin detected in fruiting bodies; no indole alkaloids in mycelium cultures; amatoxins and phallotoxins absent. Besl calls it the first record of psilocybin in Galerina

    Method: thin-layer chromatography in two systems, compared with a Psilocybe semilanceata extract. Besl 1993, Z. Mykol. 59: 215-218 (full text, Zobodat, CC BY-ND)

What the record doesn’t show: One TLC analysis of the type collection is the only chemistry, and GBIF holds just three records.

Records on file.

GBIF, the global biodiversity database, held 3 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.
