Umbilicaria esculenta, the rock tripe or Iwa-take, is a lichen of the genus Umbilicaria that grows on rocks.
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Lasallia is a genus of lichen-forming fungi in the family Umbilicariaceae. The genus was circumscribed by François Victor Mérat de Vaumartoise in 1821. The genus name Lasallia honours of Mr. Lasalle, who was a French gardener and botanist, who worked in Fontainebleau. Early molecular phylogenetics analysis of internal transcribed spacer DNA showed that the genus was monophyletic.
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.
Phaeophyscia is a genus of lichen-forming fungi in the family Physciaceae.
Rhizoplaca is a genus of lichenized fungi in the family Lecanoraceae. Members of the genus are commonly called rimmed navel lichens because of their umbilicate growth form and lecanorine apothecia, also rock-posy lichen and rockbright.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
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 rock foam lichens. Photobiont partners of Stereocaulon include green algae from the genera Asterochloris, Chloroidium, and Vulcanochloris. Stereocaulon is difficult to ID to species, but there is a high diversity of species within the genus.
Teuvo ("Ted") Tapio Ahti is a Finnish botanist and lichenologist who has made significant contributions to the taxonomy and biogeography of lichens. Known particularly for his work on the lichen family Cladoniaceae, he has had a long career at the University of Helsinki beginning in 1963, and following his retirement in 1997, has continued his research at the Botanical Museum of the Finnish Museum of Natural History. His research output spans more than seven decades, comprising over 450 scientific publications across lichenology, mycology, and botanical science.
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.
Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.
Umbilicaria angulata, commonly known as the asterisk rocktripe, is a species of saxicolous (rock-dwelling), foliose lichen in the family Umbilicariaceae. It is found in northwestern North America and east Eurasia, where it grows on acidic rock.
Umbilicaria orientalis is a species of foliose lichen belonging to the family Umbilicariaceae. It is recognized by its distinctive morphological features and unique molecular characteristics that distinguish it from closely related species such as Umbilicaria trabeculata. This lichen is primarily found across a range of localities in East Asia, extending from the Russian Far East to South Siberia, Mongolia, and regions in China including Hebei and Tibet.
