AI-generated description

Coprinopsis cinerea is a species of fungus that grows on dung, soil, and decaying organic matter. In St. Petersburg and Leningrad Oblast, it has been found in urban areas, parks, and forests, often associated with grasslands, meadows, and wooded edges. In north-western Russia, it is widely distributed, particularly in the Murmansk, Arkhangelsk, and Vologda regions, where it grows in a variety of habitats, including tundra, taiga, and agricultural lands. Fruitings typically occur from June to October, with peak abundance in July and August. The fungus is characterized by its bell-shaped to conical cap, 1-4 cm in diameter, and its deliquescent gills, which turn black and liquefy as they mature.
