Russula nauseosa is a species of mushroom that grows in association with coniferous trees, particularly spruce and pine. In St. Petersburg and Leningrad Oblast, it typically fruits from July to October in moist, acidic soils. The cap is 4-10 cm in diameter, convex to flat, and reddish-brown to brown, often with a greenish or bluish tint. The gills are cream-colored to yellowish, and the stem is white to cream-colored. In north-western Russia, Russula nauseosa is commonly found in sphagnum bogs, mossy forests, and heathlands, where it forms mycorrhizal relationships with local tree species.
