Psilocybe quebecensis
Introduction
Psilocybe quebecensis is a hallucinogenic mushroom native to the province of Quebec in Canada. It is rumored to grow wild in the valley of the river Jacques Cartier, and to fruit at a temperature of 6°C to 15°C from summer to late October. This is the most northern known psilocybin mushroom. [1]
Macroscopically this mushroom resembles Psilocybe baeocystis.
