Psilocybe quebecensis is a moderately active hallucinogenic mushroom in the section Aztecorum, having psilocybin and psilocin as main active compounds. Native to Quebec, it is the most northern known psilocybin mushroom. Macroscopically this mushroom somewhat resembles Psilocybe baeocystis.
Named for the province Quebec, where it was discovered.
Solitary to gregarious, rarely cespitose, on rotting wood, particularly in the outwashes of streams in the decayed-wood substratum of alder, birch, fir and spruce in the late summer and fall. Reported from Quebec, Canada specifically in the Jacques-Cartier River Valley, fruiting at a temperature of 6 to 15 °C (43 to 59 °F) from summer to late October. Recently found in the United States (Michigan).
[...] the so far known most northern Geophila exhibiting psychodysleptic action.
