Elaphomyces granulatus is an underground ascomycete fungus that forms mycorrhizal associations with tree roots. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to fruit in coniferous and mixed forests, typically under pine, spruce, or fir trees. The fungus produces irregularly shaped, warty, and granulate ascocarps that are 1-4 cm in diameter, with a brown to black exterior and white interior. It is considered a rare species in the region, with most records coming from late summer to early fall.
