Psilocybe plutonia is a small psilocybin mushroom of the family Hymenogastraceae, believed to contain psilocybin and psilocin. It was first documented from Cuba. An older synonym is Agaricus plutonia.
It is in the section Cordisporae.
Etymology
The word plutonia comes from the Latin words plutonian or plutonic. Perhaps in connection with the dark color of the mushroom.
