Exidia saccharina is a species of fungus that belongs to the family Auriculariaceae. It is characterized by its gelatinous, brain-like or convoluted fruiting body, typically brown to black in color. In St. Petersburg and Leningrad Oblast, as well as north-western Russia, Exidia saccharina has been found growing on deciduous trees, particularly willow, alder, and birch, often on dead or dying branches. The fungus is common in these regions, especially in moist, shaded areas with rich soil. Fruitings typically occur from late summer to early winter, with a peak in autumn.
