Summary
AI-generated from the abstractThe fungus Pholiotina cyanopus was collected from wood chips and woody debris at a closed sawmill in Żywiec, Poland. Chemical analysis using liquid chromatography–mass spectrometry detected psilocybin and its analogues psilocin, baeocystin, norbaeocystin, and aeruginascin in air-dried specimens. Psilocybin content was high at 0.90±0.08% of dry weight, with lower concentrations of psilocin (0.17±0.01%) and baeocystin (0.16±0.01%). Small amounts of norbaeocystin (0.053±0.004%) and aeruginascin (0.011±0.0007%) were reported for the first time in this species. The paper also provides a description and illustrations of the Polish specimens and discusses their ecology, distribution, and comparison with similar taxa.

Abstract
Abstract Pholiotina cyanopus was collected from wood chips and other woody remnants of undetermined tree species. Its basidiomata were found in June within the area of closed sawmill in the central part of Żywiec city (SW Poland). Description and illustration of Ph. cyanopus based on Polish specimens are provided and its ecology, general distribution and comparison with similar taxa – Pholiotina smithii, Pholiotina sulcatipes , and others are discussed as well. The identity of the active compounds of Ph. cyanopus was additionally determined. Liquid chromatography–mass spectrometry (LC-MS) data sets were obtained to support the occurrence of psilocybin and its analogues – psilocin, baeocystin, norbaeocystin, and aeruginascin in air-dried basidiomata of the species. The content of psilocybin was found to be high (0.90±0.08% of dry weight), besides, analysed samples contained lower concentrations of psilocin (0.17±0.01%), and baeocystin (0.16±0.01%). Additionally, the chemical analysis revealed small amounts of norbaeocystin (0.053±0.004%) and aeruginascin (0.011±0.0007%) for the first time in the species.
