Rock tripe

Rock tripe is the common name for various lichens of the genus Umbilicaria that grow on rocks.[1] They are widely distributed, including on bare rock in Antarctica, and throughout northern parts of North America such as New England and the Rocky Mountains. They are edible when properly prepared; soaking extensively and boiling with changes of water removes the bitterness and purgative properties.[2][3] They have been used as a famine food in extreme cases when other food sources were unavailable, as by early American northern explorers.[2]
