Extract from Wikipedia article: Agaricus bitorquis is an edible white mushroom of the genus Agaricus, similar to the common button mushroom that is sold commercially. The name supersedes Agaricus rodmani. It is also commonly known as torq, the banded agaric, spring agaric, or pavement mushroom, as it has been recorded pushing up paving slabs.
Agaricus bitorquis is a species of mushroom that grows in fields, meadows, and along roadsides. In St. Petersburg and Leningrad Oblast, it typically fruits from July to October, often in association with coniferous and deciduous trees. The fungus has been found in various habitats throughout north-western Russia, including urban areas, parks, and natural forests, where it tends to prefer well-drained soils and full sun to partial shade. Its distribution in the region is relatively widespread, with records from numerous locations, including the outskirts of St. Petersburg and surrounding rural areas.
