Umbilicaria

	Umbilicaria Rock tripe is the common name for various lichens of the genus ''Umbilicaria'' that grow on rocks. 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. They 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.

picture info	Umbilicaria Cylindrica ''Umbilicaria cylindrica'', commonly known as the fringed rock tripe, is a leafy lichen found in cold, high-altitude and polar regions across the globe. It forms roughly circular thalli measuring between 2–10 centimetres and is easily recognised with a dark upper surface bordered by a fringe of fine, hair-like projections. As one of the first colonisers of bare rock, it paves the way for more complex communities in areas exposed to intense ultraviolet light. The species is particularly abundant in Arctic–alpine environments, where it can form extensive patches on exposed boulders and rock outcrops. First described scientifically by Carl Linnaeus in 1753, the species has undergone several reclassifications as researchers have explored its varied appearances and chemical traits. While many names have been historically assigned to its various forms, current studies show that these differences are simply variations within one highly variable species.

	Umbilicaria Hyperborea ''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. Taxonomy It was first described as a new species by Swedish lichenologist Erik Acharius in 1794 as ''Lichen hyperboreus''. Georg Franz Hoffmann transferred it to the genus ''Umbilicaria'' in 1796. In a 2017 molecular phylogenetic analysis of the genus ''Umbilicaria'', ''U. hyperborea'' was proposed as the type species of the subgenus ''Umbilicaria''. Closely related species include '' U. polyphylla'', '' U. iberica'', and '' U. arctica''. Description The thallus of ''Umbilicaria hyperborea'' ranges in colour from medium- to dark-brown, with texture of the upper surface more or less smooth or warty. The thallus undersurface is smooth, and there are not any rhizines. The disc-shaped apothecia are flat to convex and have multiple complex ridges. Habitat and distribution The lich ...

	Umbilicaria Leiocarpa ''Umbilicaria leiocarpa'', commonly known as textured rock tripe, is a species of saxicolous (rock-dwelling), lichen in the family Umbilicariaceae. First described by Augustin Pyramus de Candolle in 1805, it is characterised by its small to medium-sized grey thallus with a cracked upper surface and smooth reproductive structures. The species has a primarily Holarctic distribution, being found across Europe from Fennoscandia to the Pyrenees, with populations occurring from sea level to alpine elevations around . It shows a particular preference for siliceous rock substrates and is absent from northern Lapland despite being common in similar habitats elsewhere in Fennoscandia. The species belongs to the subgenus ''Agyrophora'', one of eight recognised subgenera within ''Umbilicaria'', and is distinguished by its smooth, non- thallus and distinctive asexual reproduction through specialised structures called .
