Auricularia auricula-judae

Auricularia auricula-judae (also known as Jew's ear, wood ear, jelly ear or by a number of other common names) is a species of fungus in the family Auriculariaceae. It is a common and widespread species, found in many parts of the world.

Taxonomy

The species was first described scientifically by Carl Linnaeus in 1753 as Hirneola auricula-judae. The specific epithet is derived from the belief that Judas Iscariot, hanged himself from an elder tree; the common name "Judas's ear" eventually became "Jew's ear", while today "jelly ear" and other names are sometimes used. The fungus was transferred to the genus Auricularia in 1888 by Joseph Schröter, a German mycologist.

Its specific epithet is derived from the belief that Judas Iscariot hanged himself from an elder tree; the common name "Judas's ear" eventually became "Jew's ear", while today "jelly ear" and other names are sometimes used.

Distribution and habitat

Auricularia auricula-judae is found globally, and is common in all temperate regions, including North America, Europe, and Asia. It is a saprophytic species that lives on dead and decaying wood, particularly elder.
