Rock tripe is the common name for various lichens of the genus Umbilicaria that grow on rocks.[1] They can be found throughout northern parts of North America such as New England and the Rocky Mountains. They are edible when properly prepared and have been used as a famine food in extreme cases when other food sources were unavailable, as by early American northern explorers.

Umbilicaria esculenta is commonly used as a food in Asian cuisine and a restorative medicine in traditional Chinese medicine. It is called shi'er (石耳 "rock ear") in Chinese cuisine, iwatake (岩茸 "rock mushroom") in Japanese cuisine, and seogi (석이버섯) in Korean cuisine.
