The 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.
