AI-generated description

Scleroderma areolatum is a species of fungus that belongs to the family Sclerodermataceae. It is characterized by its globose to subglobose basidiocarps, which are 2-6 cm in diameter, with a thick, hard peridium and a powdery, yellowish-brown gleba. In St. Petersburg, Leningrad Oblast, and north-western Russia, Scleroderma areolatum has been found growing in coniferous and mixed forests, often associated with sandy or podzolic soils.
