SPECIES ATLAS · INOCYBE

Inocybe asterospora

Named by Quél., 1880

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.

Quélet described Inocybe asterospora in the Bulletin de la Société Botanique de France 26: 50, dated 1879 and published 1880. Index Fungorum and GBIF accept the original name.

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. 2026

    Reported Psilocybin detected together with muscarine, but no psilocin, in Chinese specimens; the authors call it the first report of psilocybin in a nodulose-spored lineage

    Method: LC-MS/MS. Liang et al. 2026, MycoKeys 141: 23-44 (full text PMC13643354)

What the record doesn’t show: A single 2026 study of Chinese specimens; no European collection of this widespread species has been reported positive in the sources read.

Records on file.

GBIF, the global biodiversity database, held 7,292 occurrence records under this name, 9 of them from Canada, when we checked on October 25, 2026. GBIF lists 9 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.
