Exidia crenata is a species of fungus in the family Auriculariaceae. It has the English name of amber jelly roll. Basidiocarps (fruit bodies) are gelatinous, brown to orange-brown, and turbinate (top-shaped). It typically grows on dead attached twigs and branches of broadleaved trees and is found in North America.
The species was originally described from North Carolina in 1822 by German-American mycologist Lewis David de Schweinitz as Tremella crenata. It was transferred to the genus Exidia by Fries in the same year. Exidia crenata was widely considered a synonym of the European Exidia recisa[1] until molecular research, based on cladistic analysis of DNA sequences, showed that the American species is distinct.[2]
