SPECIES ATLAS · PANAEOLUS

Panaeolus tropicalis

Named by Ola'h, 1969

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.

Ola'h described Panaeolus tropicalis in 1969 in Revue de Mycologie; Index Fungorum gives the type as 'Heim s.n.'. Singer and Weeks later placed it in Copelandia, the name Merlin & Allen (1993) still used. Species Fungorum keeps it in Panaeolus.

Named
Ola'h, 1969
Other names in the records
Copelandia tropicalis (Ola'h) Singer & Weeks (as given by Merlin & Allen 1993)
Type specimen
Index Fungorum lists 'Cambodia, Central Africa' for the protologue and the type as 'Heim s.n.'; Strauss et al. (2023) give Cambodia as the type country. (Index Fungorum record, Panaeolus tropicalis)
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 Listed as Copelandia tropicalis among Hawaiian species 'now known to contain psychoactive alkaloids', combining earlier analyses with the authors' own; the abstract does not say which analyses covered this species

    Method: not stated in abstract. Merlin & Allen 1993, J. Ethnopharmacol. 40: 21-40 (abstract)

  2. 2023

    Reported Listed in a review table as containing psilocybin and psilocin, citing Andersson et al. 2009, Merlin & Allen 1993 and Pollock 1976; listed in Strauss et al. 2023 without its own analysis

    Method: review (no analysis). Strauss et al. 2023, Heliyon 9: e16338, Table 3 (full text, PMC10238702)

What the record doesn’t show: Only five GBIF records exist, and the one primary paper we could check gives no species-level method in its abstract.

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.
