Psilocybe azurescens

Psilocybe azurescens is a species of psychedelic mushroom whose main active compounds are psilocybin and psilocin. It is among the most potent of the tryptamine-bearing mushrooms, containing up to 1.8% psilocybin, 0.5% psilocin, and 0.4% baeocystin by dry weight, averaging to about 1.1% psilocybin and 0.15% psilocin.
