Aeruginascin or N,N,N-trimethyl-4-phosphoryloxytryptamine is an indoleamine derivative which occurs naturally within the mushroom Inocybe aeruginascens and Pholiotina cyanopus. Aeruginascin is the N-trimethyl analogue of psilocybin. It is closely related to the frog skin toxin bufotenidine, a potent 5-HT3 receptor agonist.
