|Scientific Name||Stropharia caerulea|
|Average Mushroom height (CM)||9|
|Average Cap width (CM)||8|
Has a long-lasting white ring, the top surface of which becomes coloured with the brown spores.
The only similar looking mushroom is the Verdigris Agaric (Stropharia aeruginosa), which is rarer and has white edged gills.
Purple/brown. Ellipsoid. The spores should be scrapped into a small pile to get an accurate spore colour.
This mushroom suspected to contains psilocybin and psilocin, powerful hallucinogens. There is a single study back from 1981 which reported these substances from the fruit body of S. caerulea, but it seems to be just a mistake, because none of the later analytical studies were able to find any of these even in traces.
This mushroom will also cause gastric upsets so is not a safe mushroom for consumption.
