Extract from Wikipedia article: Scleroderma citrinum, commonly known as the common earthball, pigskin poison puffball, or common earth ball, is the most common species of earthball in the UK and occurs widely in woods, heathland and in short grass from autumn to winter. Scleroderma citrinum has two synonyms, Scleroderma aurantium (Vaill.) and Scleroderma vulgare Horn.
Scleroderma citrinum is a species of fungus that belongs to the family Sclerodermataceae. It is characterized by its yellow to orange-colored basidiocarps, which are spherical to ellipsoidal in shape and typically 2-6 cm in diameter. In St. Petersburg, Leningrad Oblast, and north-western Russia, Scleroderma citrinum has been found to grow in a variety of habitats, including coniferous and deciduous forests, as well as in urban areas. It is often associated with sandy or acidic soils and can be found fruiting from summer to autumn. The fungus is considered to be relatively common in the region, particularly in areas with abundant pine and spruce trees.
