Extract from Wikipedia article: Russula xerampelina, also commonly known as the crab brittlegill or the shrimp mushroom, is a basidiomycete mushroom of the brittlegill genus Russula. Two subspecies are recognised. The fruiting bodies appear in coniferous woodlands in autumn in northern Europe and North America. Their caps are coloured various shades of wine-red, purple to green. Mild tasting and edible, it is one of the most highly regarded brittlegills for the table. It is also notable for smelling of shellfish or crab when fresh.

AI-generated description

Russula xerampelina is a species of fungus that belongs to the family Russulaceae. It has a cap that ranges from 4-12 cm in diameter, typically reddish-brown to purple-brown in color, and often has a wrinkled or cracked appearance. The gills are cream-colored to yellowish, and the stem is white to pale yellow. In St. Petersburg, Leningrad Oblast, and north-western Russia, Russula xerampelina is commonly found in coniferous forests, particularly under spruce and pine trees, during late summer and early autumn. It is considered a edible mushroom in the region, with a shrimp-like or seafood-like odor when fresh.

AI-generated summary of observations

Observations of Russula xerampelina in Leningrad Oblast and north-western Russia reveal the fungus's presence in various locations. Near Dibuny, west of Saint Petersburg, crab brittlegill mushrooms were found on September 7, 2016. The species was also spotted in Kannelyarvi, approximately 45 miles north of Saint Petersburg, on August 11, 2017, where they displayed a dark red coloration. These sightings suggest that Russula xerampelina can be found in the region during late summer, with varying colors and possibly different habitats. The fungus appears to thrive in the area's temperate climate, with observations recorded in both late August and early September. Further study could provide insight into the species' distribution, growth patterns, and ecological role in the region. Additional observations may help confirm the timing and range of Russula xerampelina in Leningrad Oblast and north-western Russia.
