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]
Umbilicaria esculenta is commonly used as a food in Asian cuisine and a restorative medicine in traditional Chinese medicine.
Cetraria is a genus of fruticose lichens that associate with green algae as photobionts. Most species are found at high latitudes, occurring on sand or heath. Species have a characteristic "strap-like" form, with spiny lobe edges.
Umbilicaria esculenta, the rock tripe, is a lichen of the genus Umbilicaria that grows on rocks.
Collema is a genus of lichens in the family Collemataceae. The photobiont is the cyanobacterium genus Nostoc. Species in this genus typically grow on nutrient-rich bark or somewhat siliceous or calcareous rocks in humid environments.
Trapeliopsis is a genus of lichenized fungi in the family Trapeliaceae. It contains 20 species. The genus was circumscribed in 1980 by Hannes Hertel and Gotthard Schneider, with Trapeliopsis wallrothii designated as the type species.
Heterodermia is a genus of lichenized fungi in the family Physciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 80 species.
Phaeophyscia is a genus of lichen-forming fungi in the family Physciaceae.
Peltula is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ) or terricolous. Members of the genus are commonly called rock-olive lichens. They are cyanolichens, with the cyanobacterium photobiont from the genus Anacystis. They are umbilicate with flat to erect squamule lobes that attach from a central holdfast or cluster of rhizenes. Lichen spot tests are usually negative.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Stereocaulon is a genus of lichens. Members of Stereocaulon are commonly called snow lichens.
Umbilicaria hyperborea, commonly known as blistered rock tripe, is a species of foliose lichen in the family Umbilicariaceae. It is widely distributed in arctic and alpine regions.
Scytinium is a genus of lichen-forming fungi in the family Collemataceae. It has 49 species. These lichens are typically found on basic rocks, soil, and trees, occasionally in association with mosses. Despite the morphological and ecological diversity within Scytinium, its species share similar ascospore features, such as shape and septation, as well as a small to medium-sized thallus with at least a partial cortex.
