Lycoperdon excipuliforme is a species of puffball fungus that grows up to 10-20 cm in diameter, with a spherical or pear-shaped cap and a short, stout stem. In St. Petersburg and Leningrad Oblast, it typically fruits from July to October in coniferous and mixed forests, often on sandy soils. In north-western Russia, it is widely distributed and can be found in various habitats, including forest edges, clearings, and along roadsides, usually associated with pine, spruce, or birch trees. The fungus is considered rare in the region, but can be locally abundant in suitable areas.

Old Pestle puffball mushroom (Lycoperdon excipuliforme, Calvatia excipuliformis, Handkea excipuliformis) near Lisiy Nos, west from Saint Petersburg. Russia, September 12, 2016Primorskoye sh., g. Sankt-Peterburg, Russia, 197755Observations of the fungus Lycoperdon excipuliforme in Leningrad Oblast and north-western Russia reveal its presence in various stages of maturity. On August 23, 2016, near Lisiy Nos, west of Saint Petersburg, young pestle puffball mushrooms were found. By September 3, 2016, mature specimens were observed in the same area, but south of Saint Petersburg. Later, on September 12, 2016, old and likely decayed mushrooms were spotted near Lisiy Nos, indicating the fungus's life cycle progression over time. These sightings suggest that Lycoperdon excipuliforme grows and matures rapidly, with a lifespan of several weeks, in the region's environment. The consistent appearance of this species in the area implies it is well-adapted to the local conditions in Leningrad Oblast and north-western Russia.
