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]
The gelatinous fruit bodies are amber, 8–25 millimetres (3⁄8–1 inch) wide, and 4–12 mm (3⁄16–1⁄2 in) thick. They can be translucent and tend to be moist and/or glossy. The spore print is white. [3]
Similar species include E. recisa and members of Auricularia and Phaeotremella. [3]
Exidia crenata is a wood-rotting species, typically found on dead attached twigs and branches of broadleaf trees, particularly oak. [1] It is widely distributed in eastern North America, where it can be found from September through May, thriving in winter. [3]
