Umbilicaria Antarctica
Rock tripe is the List of common names of lichen genera, 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.

Umbilicaria Aprina
''Umbilicaria aprina'' is a species of foliose lichen in the family Umbilicariaceae. It is primarily found on exposed boulders in high alpine and polar regions worldwide. Taxonomy ''Umbilicaria aprina'' was first described by the Finnish lichenologist William Nylander in 1863. He later (1891) proposed it be reclassified in genus ''Gyrophora''. The holotype of ''Umbilicaria aprina'' was collected from Ras Dashen in Ethiopia, at an elevation of about . Description The thallus of ''Umbilicaria aprina'' is single-leaved (), shield-shaped (), and rigid, measuring up to in diameter. The upper surface is light grey, typically featuring radiating ridges from the central, elevated point known as the . The lower surface is predominantly sooty black with a light grey rim about 2–3 mm wide along the margins. This lower surface is covered with single-celled reproductive propagules known as and adorned with white —root-like extensions that are unbranched or sparsely branched and ...

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 . Taxonomy The species was scientifically described as new to science in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbilicaria Isidiosa
''Umbilicaria isidiosa'' is a species of foliose lichen belonging to the family Umbilicariaceae. It is endemic to Bolivia, where it occurs in high-altitude regions of the Bolivian Andes. It is distinguished by its thallus, which has an upper surface ranging from ashy brown to mouse grey, featuring a frosty () texture that varies from smooth to slightly rough. This surface is adorned with numerous isidia (reproductive propagules), ranging from spherical to richly branched, primarily concentrated along the margins. The lower surface is dark, transitioning from smooth to rough in texture, and sparsely covered with dark rhizines (root-like structures). Taxonomy This species was first described by the Polish lichenologist Beata Krzewicka in 2009. The type specimen of ''Umbilicaria isidiosa'' was collected by Adam Flakus northwest of Comarapa city, near the village of Siberia, within the Santa Cruz Department's Manuel María Caballero Province. Found at an elevation of , the specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They are edible when properly prepared; soaking extensively and boiling with changes of water removes the bitterness and purgative properties.

Umbilicaria Deusta
''Umbilicaria deusta'', commonly known as peppered rock tripe, is a widely distributed species of saxicolous lichen in the family Umbilicariaceae. It was first described by Carl Linnaeus in his 1753 work ''Species Plantarum'' as ''Lichen polyphyllus''. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus ''Umbilicaria'' in 1790. The lichen has a dark brown to nearly black thallus that typically measures in diameter. The upper surface is covered with tiny black dots that are granular isidia An isidium (plural: isidia) is a tiny, wart- or finger-like outgrowth on the thallus surface of certain lichen species. It is one of two principal types of vegetative reproduction, vegetative reproductive structures in lichens, the other being ...; the lower surface is the same colour as the upper surface, and is either smooth or covereds with dimples. It grows on exposed boulders and rocky outcrops. References deusta Lichen species Taxa named by Carl L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbilicaria Decussata
''Umbilicaria decussata'' is a widespread species of saxicolous (rock-dwelling) foliose lichen in the family Umbilicariaceae. It typically grows in high-elevation alpine environments. Taxonomy It was described as a new species in 1789 by the French botanist and lichenologist Dominique Villars, who placed it in the eponymous genus ''Lichen''. In his original description, Villars characterised the species as a cartilaginous lichen with a black lower surface and brown upper surface, divided into three to five wedge-shaped segments that form a cross-like pattern in the centre. He noted its distinctive transverse wrinkles and reticulated folds formed by the raised epidermis, and observed that fruiting bodies, appearing as large black spots, were rare along the margins. The type locality was given as granitic rocks in the high Alps, specifically mentioning the areas of Valgaudemar, Champoléon, and Vieux Chaillol. Villars also tentatively linked his species to an earlier illustrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
