Extract from Wikipedia article: Sarcosoma globosum, or witches cauldron, is a species of fungus in the family Sarcosomataceae. It was first described in 1793 by Casimir Christoph Schmidel. Johann Xaver Robert Caspary transferred it to the genus Sarcosoma in 1891.
Sarcosoma globosum is a rare, saprotrophic fungus that grows on soil and decaying organic matter. In St. Petersburg and Leningrad Oblast, it has been found in coniferous and mixed forests, typically in areas with rich soil and abundant leaf litter. In north-western Russia, the species has been recorded in various regions, including the Karelian Isthmus and the Murmansk Oblast, often associated with mosses and lichens. The fungus produces globose to subglobose fruiting bodies, 2-5 cm in diameter, with a smooth, yellow-brown to dark brown exterior and a pale interior.

Russia, May 14, 2021Primorskoye Hwy, Sankt-Peterburg, Russia, 197755Observations of Sarcosoma globosum in Leningrad Oblast and north-western Russia reveal that the fungus grows under large spruce trees, often in mossy areas. Mature specimens were found between Lisiy Nos and Morskaya, west of Saint Petersburg, on May 3, 2021, and May 14, 2021. The mushrooms were also displayed at the Botanic Gardens of Komarov Botanical Institute in Saint Petersburg on May 28, 2017. The habitat of Sarcosoma globosum was observed to be near a forest road and a swamp with moss. Dissected specimens were taken from a spruce forest, and close-ups of old mushrooms showed their characteristic charred-pancake cup shape. The fungus appears to thrive in the region's spruce forests, particularly in areas with abundant moss. Multiple observations suggest that Sarcosoma globosum is present in the area from May, with both mature and old specimens found during this time.
