Auricularia auricula-judae is a saprobic European jelly fungus with traditional culinary and medicinal significance, often said to resemble a human ear. It was originally named Tremella auricula by Linnaeus and has been moved to different genera since, but its specific epithet was also changed from auricula to auricula-judae by Bulliard in 1789, which is not normally a valid nomenclatural alteration. However, due to the practice of "name sanctioning" in the mycological nomenclatural code, this change has been accepted. This article outlines the nomenclatural and cultural history of the controversial name Auricularia auricula-judae and suggests its return to the original specific epithet auricula, as well as the designation of an epitype specimen.
