Psilocybe Tampanensis - Taxonomy

Taxonomy

The species was described scientifically by Steven H. Pollock and Mexican mycologist and Psilocybe authority Gastón Guzmán in a 1978 Mycotaxon publication. According to Paul Stamets, Pollock skipped a "boring taxonomic conference" near Tampa, Florida to go mushroom hunting, and found a single specimen growing in a sand dune, which he did not recognize. Pollock later cloned the specimen and produced a pure culture, which remains widely distributed today. The type specimen is kept at the herbarium of the Instituto Politécnico Nacional in Mexico. Guzmán classified P. tampanensis in his section Mexicanae, a grouping of related Psilocybe species characterized primarily by having spores with lengths greater than 8 micrometers.
