Pholiotina cyanopus
（重定向自Conocybe Cyanopus）
Pholiotina cyanopus is a species of fungus currently assigned to the genus Pholiotina that contains the psychoactive compound psilocybin. Originally described as Galerula cyanopus by American mycologist George Francis Atkinson in 1918. It was transferred to Conocybe by Robert Kühner in 1935 before being transferred to Pholiotina by Rolf Singer in 1950. A 2013 molecular phylogenetics study found it to belong to a group of species currently assigned to Pholiotina that are more closely related to Galerella nigeriensis than to Pholiotina or Conocybe. It is likely that it will be moved to a different genus in the future, but this has not happened yet.
