Umbilicaria esculenta

Umbilicaria esculenta is a lichen of the genus Umbilicaria that grows on rocks. It can be found in East Asia including in China, Japan, and Korea . It is edible when properly prepared and has been used as a food source and medicine. It is called iwatake (kanji: 岩茸 or 石茸) in Japanese and seogi (hangul: 석이; hanja: 石耳; literally "stone ear" or "rock ear") in Korean. The species name is based on the earlier basionym Gyrophora esculenta.
