Otidea genus of fungi in the family Pyronemataceae. The genus is widely distributed in northern temperate regions.
The genus, proposed in 1851 by German physician and mycologist Hermann Friedrich Bonorden , was based on Christiaan Hendrik Persoon 's 1822 Peziza Otidea . Otidea is probably derived from the Greek words οϋς (ous), gen. ώτός (otos), meaning "ear", referring to the fruitbody shape of some species.
