I have on one occasion mixed high dose amanita muscaria with tiny dose psilocybin.
the amanita i picked and dried myself. they were large, beautiful specimens collected on the south island, NZ.
I made a tea with 33 dried grams, and ate it like soup--tasted good.
the powdered psilocybin gel caps fell from the stars at a festival. i had previously taken 4 by themselves, and was nice, visual.
i cant remember if i took one or two with the amanita, but it was a low dose, nonetheless.
it was not an extremely powerful experience, i can compare it to drinking of san pedro tea. visual, beautiful, insightful, but not out of body, and no breakthru.
i certainly do not recommend this dose, as amanita can vary greatly in potency. the also may be more potent if just eaten, dried.
