Summary
AI-generated from the abstractAn analysis of twenty mushroom species from seven genera in the Pacific Northwest detected psilocybin—and sometimes psilocin—in seven species across three genera. The amount of these compounds varied more than sevenfold between different collections of the same species. In mushrooms used recreationally or entheogenically, total psilocybin and psilocin levels ranged from 0.1% to nearly 2% of dry weight.

Abstract
The analysis of twenty species from seven genera of Pacific Northwest mushrooms revealed psilocybin (and in some cases psilocin as well) in seven species from three genera. The species found to contain psilocybin (and psilocin) varied from one collection to another by more than a factor of seven in amount present. Total psilocybin and psilocin levels in species known to be in use for recreational and entheogenic purposes varied from 0.1% by dry weight up to a high of nearly 2% by dry weight.
