The only psychoactive mushrooms I'm aware of that will grow on wood are Amanita muscaria, and they're not to be considered in the same class as Psilocybe or Panaeolus mushrooms. The difference between a "therapeutic" dose of Amanita and a lethal one is a bit close for my comfort level. You likely couldn't hold a lethal dose of Psilocybes or Panaeolus down long enough to actually metabolize it. Be careful out there!
