Lasallia
''Lasallia'' is a genus of lichen-forming fungi in the family Umbilicariaceae. These lichens are recognizable by their distinctive warty, blister-covered thallus surface and their unusual saxicolous lichen, attachment to rocks using only a single, sturdy central connection point. They typically grow on granite and other hard rock surfaces, where they can survive in both sunny and shaded locations. The genus contains six accepted species that are found across various continents, with some species being quite common on stone walls and cliff faces. Taxonomy The genus was circumscription (taxonomy), circumscribed by François Victor Mérat de Vaumartoise in 1821. The genus name ''Lasallia'' honours Mr. Lasalle (died around 1820), 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. More recent work has refined the generic concept. In 2010 Davydov, Perš ...

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 ...

Fulgidea
''Fulgidea'' is a genus of lichen-forming fungi in the family Umbilicariaceae. It has two species of squamulose lichens that grow on bark and on wood. Taxonomy The genus was circumscribed in 2013 by the Norwegian lichenologists Mika Bendiksby and Einar Timdal. They assigned '' Fulgidea oligospora'' as the type species. The genus name ''Fulgidea'' is derived from the Latin word , meaning "lightning", alluding to its preference for growing on burnt wood. The name also reflects its morphological similarities to species within the genus ''Lecidea''. Both species of ''Fulgidea'' had previously been classified in the genus '' Hypocenomyce''. Description Genus ''Fulgidea'' is characterized by its squamulose thallus, which is closely attached or slightly raised and oriented against gravity. The thallus ranges in color from greyish-green to dark brown and can have either a dull or shiny appearance. It lacks a coating (a fine powdery surface layer that sometimes appears frosted) and ...

Umbilicariales
The Umbilicariales are an order of lichenized fungi in the subclass Umbilicariomycetidae, class Lecanoromycetes. It contains five families: Elixiaceae, Fuscideaceae, Ophioparmaceae, Ropalosporaceae, and Umbilicariaceae. Umbilicariales was proposed as a new order in 2007, while the subclass Umbilicariomycetidae was proposed in 2013. Families and genera , Species Fungorum accepts 5 families, 18 genera, and 107 species in the order Umbilicariales: * Elixiaceae ::'' Elixia'' – 2 spp. ::'' Meridianelia'' – 1 sp. * Fuscideaceae ::'' Albemarlea'' – 1 sp. ::'' Fuscidea'' – 31 spp. ::'' Hueidea'' – 1 sp. ::'' Lettauia'' – 2 sp. ::'' Maronea'' – 2 spp. ::'' Maronora'' – 1 sp. ::'' Orphniospora'' – 2 spp. * Ophioparmaceae ::'' Boreoplaca'' – 1 sp. ::'' Hypocenomyce'' – 5 spp. ::'' Ophioparma'' – 4 spp. * Ropalosporaceae ::'' Ropalospora'' – 8 spp. *Umbilicariaceae ::'' Fulgidea'' – 2 spp. ::''Lasallia'' – 5 spp. ::''Umbilicaria Rock tripe is the com ...

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.

Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal ecosystems are some of the most vulnerable to climate change. Both loss of permafrost, reductions in cold weather and increases in summer heat cause significant changes to ecosystems, displacing cold-adapted species, increasing forest fires, and making ecosystems vulnerable to changing to other ecosystem types. These changes can cause Climate change feedback cycles, where thawing permafrost and changing ecosystems release more greenhouse gas emissions into the atmosphere causing more clima ...

Lecanoromycetes Families
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence. The group is monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent co ...

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...
