Pholiotina cyanopus was originally described as a Galerula in 1918 where it was found in the Northeastern region of the Unites States (Ithaca, New York State). In 1935, with enhanced knowledge of microcharacters and their use for generic criteria, the specie was transferred to the Conocybe genus to be finally placed in Pholiotina genus in 1950.
Today it is nonetheless referred to as Conocybe cyanopus by many mycologists. This unsettled genus situation is most likely to change again in the future. It is yet another example of the complexity and ongoing exploration of the vast terrain of mycology.
Similar in appearance to Conocybe (Pholiotina) smithii and in potency to Psilocybe semilanceata, this rare midget psychedelic mushroom is of remarkable potency for its size. Psychedelic mushroom hunters must beware of its resemblance to some Galerinas, which are highly poisonous!
Conocybe cyanopus is said to contain trace amounts of the rare compound aeruscinagin. It is amongst the rare strains to form sclerotia, the dormant form of the fruiting body commonly named truffles”, or “psilocybin stones”, which can also be consumed for their psychoactive properties.
Reported from North America, temperate Asia and Central and Northern Europe, this discrete cone-headed hallucinogenic mushroom is probably widely distributed across the temperate regions of the world but often passes under the radar because of its petite stature.
