Extract from Wikipedia article: Russula albonigra is a member of the genus Russula, all of which are collectively known as brittlegills.
Russula albonigra is a medium-sized mushroom with a white to cream cap that often bruises blackish, and a white stem. In St. Petersburg and Leningrad Oblast, it typically grows in coniferous forests, especially under spruce and pine trees. In north-western Russia, it fruits from July to September, preferring moist, acidic soils. The species is considered rare in the region, but can be found in areas with suitable habitat, such as the Karelian Isthmus and the Valdai Hills.

Blackened mature menthol brittlegill mushroom (Russula albonigra) in Tarkhovka Park, west from Saint Petersburg. Russia, August 2, 2024Observations of Russula alnonigra were made in various locations across Leningrad Oblast and north-western Russia. The fungus was found near Kavgolovskoe Lake in Toksovo, Pesochnaya, Tarkhovka Park, Lembolovo, and Lisiy Nos. The mushrooms were observed growing in different environments, including roadside areas and parks. They were spotted during the summer months, from July to September, with some observations made over multiple years. Dissected specimens were also examined, providing further insight into the fungus's characteristics. Additionally, mature specimens were found to become blackened over time, as seen in Tarkhovka Park in 2024. The widespread presence of Russula alnonigra in these regions suggests that it is a common species in north-western Russia.
