Aeruginascin
Aeruginascin or N,N,N-tri methyl-4-phosphoryloxy tryptamine is an indoleamine derivative which occurs naturally only within the mushroom Inocybe aeruginascens. Aeruginascin is the N-tri methyl analogue of psilocybin. It is closely related to the frog skin toxin bufotenidine (5-HTQ), a potent 5-HT receptor agonist, and has been found exclusively in Inocybe aeruginascens.
