Psilocybe atrobrunnea

Psilocybe atrobrunnea is a dark brown mushroom of raised Sphagnum bogs and wet conifer and hardwood forest across the boreal north, from Finland, Sweden and Siberia to Britain and eastern North America. It fruits from May to October, peaking in autumn. It is hard to cultivate because of its bog habitat.
