Exidia candida is a species of fungus in the family Auriculariaceae. Basidiocarps (fruit bodies) are gelatinous, whitish, and cushioned-shaped at first, becoming effused and corrugated. It typically grows on logs and fallen branches of lime (Tilia species) and other broadleaved trees. The species occurs in both North America and Europe. A distinctive variety, Exidia candida var. cartilaginea, is bicoloured whitish and ochre to brown, grows preferentially on birch and alder, has a northerly distribution, and occurs in North America, Europe, and the Russian Far East....read more on Wikipedia.
