Summary ²

Rock tripe is the common name for various lichens of the genus Umbilicaria that grow on rocks. 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 food source in extreme cases when other food sources were unavailable, as by early American northern explorers.
