Extract from Wikipedia article: Lycoperdon pyriforme, commonly known as the pear-shaped puffball or stump puffball, is a saprobic fungus present throughout much of the world. Emerging in autumn, this puffball is common and abundant on decaying logs of both deciduous and coniferous wood. It is considered a choice edible when still immature and the inner flesh is white.
Lycoperdon pyriforme is a species of puffball fungus that grows up to 6 cm in diameter, with a pear-shaped or spherical fruiting body, often with a short stalk. In St. Petersburg and Leningrad Oblast, it typically fruits from July to October in deciduous and mixed forests, especially in areas with rich soil and abundant leaf litter. In north-western Russia, it is widely distributed and can be found in various habitats, including parks, gardens, and along roadsides, often associated with trees such as birch, aspen, and willow. The fungus is considered edible when young and immature, but caution is advised due to potential confusion with poisonous lookalikes.
