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.
Guzmán and Watling described Psilocybe eucalypta in 1978 in Notes from the Royal Botanic Garden Edinburgh 36(1): 204, from New South Wales. Index Fungorum and GBIF accept the name unchanged.

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.
- 1981
Reported Psilocybin reported (Margot & Watling 1981, Studies in Australian agarics and boletes II); listed in Bradshaw Table S1 with a voucher at the University of Strathclyde
What the record doesn’t show: One 1981 report only, not opened here, and GBIF holds just five occurrence records.
Records on file.
GBIF, the global biodiversity database, held 5 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.
