Blue cap mushroom

Blue cap mushroom

Blue cap mushroom, commonly known as blue round head mushroom, is a type of mushroom forming fungus in the family Agaricus. It is a relatively common species found in Europe and North America, where it grows as a saprophytic plant in grasslands, roadsides, hedgerows, gardens, and sawdust coverings. S. Caerulea was officially described by the scientific community in 1979, despite being a unique species for approximately two centuries prior to that. The scientific name "Stropharia cyanea" defined by Tuomikoski in 1953 is synonymous with S. caerulea and was later used by several authors.
