Psychoactive mushrooms contain either psilocybin (in the case of psilocybes) or ibotenic acid (in the case of amanita/fly argaric).

Mushrooms that contain psychoactives contain psilocybin, psilocin and baeocystin (in the case of psilocybe mushrooms) or ibotenic acid and muscimol (in the case of amanita/fly argaric mushrooms)

Psilocybin does not have any harmful effects. The reason being is that its toxicity is about 1.5 times the amount of caffeine, meaning that you would need possibly 1kg+ worth of mushrooms to kill yourself. The mushrooms are not as toxic as amanita muscaria (toadstools), which contain ibotenic acid, a deadly compound.
