Summary
Certain Norwegian mushrooms, *Psilocybe semilanceata*, contain potent hallucinogenic psilocybin, with dried samples showing concentrations from 0.17 to 1.96%. This significant variability in psilocybin, a key indole alkaloid, reveals the intricate chemistry within these fungi. Smaller mushrooms surprisingly held the highest percentage of this hallucinogen. This insight into plant and fungal interactions is crucial for Psychedelics and Drug Studies, informing chemical synthesis and alkaloids research. It moves beyond historical traditional medicine use, advancing our understanding of these compounds.
Abstract
Psilocybe semilanceata contains hallucinogenic indole alkaloids and has been used as a narcotic drug in Norway. The content of psilocybin, the major constituent in Norwegian P. semilanceata, has been investigated as well as its habitats and its distribution throughout the country. The mushroom is growing on grassy sites in most parts of Norway from the middle of August to the middle of October. The psilocybin content in dried mushrooms varied considerably, from 0.17 to 1.96%. The highest concentrations in percent was found among the smaller mushrooms whereas the content in mg was highest in larger mushrooms. The content of psilocybin makes P. semilanceata to a potent hallucinogenic drug.
