The hallucinogenic mushroom Psilocybe semilanceata, widely distributed in Finland, contains high levels of psilocybin, ranging from 0.62% to 2.37% of dry weight, with a mean of 1.42%. Some samples also contain low concentrations of psilocin, between 0.01% and 0.02% of dry weight. These findings, determined by HPLC analysis of samples from different parts of Finland, provide quantitative data on the psychoactive alkaloid content of this species.
