AI-generated description

Cortinarius quarciticus is a species of fungus that grows in association with coniferous trees, particularly spruce and pine. In St. Petersburg and Leningrad Oblast, it has been found in forests and wooded areas, typically fruiting from late summer to early autumn. In north-western Russia, the species is relatively common, often occurring in moist, acidic soils with abundant moss and lichen cover. The fungus produces small to medium-sized fruit bodies with bell-shaped caps that range in color from yellow-brown to reddish-brown, and slender stems that are typically pale yellow or whitish.
