Psilocybe mesospora

A Psilocybe described by Rolf Singer in 1969 from southern South America. The only GBIF records are 1995 field observations on the Quetrihué peninsula in Los Arrayanes National Park, Neuquén, a cool, wet Andean lake forest. Whether it contains psilocybin is not documented here; many Psilocybe do and are controlled in many countries, so check local law before any cultivation.
