Species atlas

Six species, six origin stories

Who named them, when, and where their type specimens came from.

Cuba, 1904

Psilocybe cubensis

Collected in Cuba on 19 June 1904 and published by Earle as Stropharia cubensis in 1906. Rolf Singer moved it to Psilocybe in 1948.

Sweden, 1818

Fries published it as Agaricus semilanceatus in 1818, and Kummer moved it to Psilocybe in 1871. Its type is an illustration by Sowerby, not a specimen.
