AI-generated description

Discina ancilis is a species of fungus in the family Discinaceae. It is found in St. Petersburg, Leningrad Oblast, and north-western Russia, typically growing on calcareous soils, moss, and detritus in forests and grasslands. The fungus produces small to medium-sized, cup-shaped fruiting bodies with a white to cream-colored hymenium and a short, stout stem. It fruits from spring to autumn, often in association with other fungi and plants that thrive in alkaline environments. Records of Discina ancilis in the region indicate it is a relatively rare but widespread species in north-western Russia.
