Two different types of polysaccharides are known to be the structural components, both a heteroglycan from the fungus and a glucan from the alga.[1] U. esculenta lichens have a thallus attached to the substrate with a central holdfast.[2] The thallus is also heteromerous (parts that are different in quality and number) and fully corticated (has a cortex and bark). Many of the Umbilicaria species are characterized by a veined or rugose thalline surface.[2]
Umbilicaria esculenta is a saxicolous lichen; it grows on rocks and is known widely as the "rock tripe". It is usually found on at high altitude in East Asia.[3]
U. esculenta is considered a delicacy in China, Korea, and Japan where it is eaten in dishes, soups, or in salads.[4]
It has been used as starvation food by Native Americans and early settlers.[4]
