Arctomia Papuanorum
''Arctomia'' is a genus of lichen-forming fungi in the family Arctomiaceae. The genus was originally circumscription (taxonomy), circumscribed by Theodor Magnus Fries in 1861. ''Arctomia'' has a circumpolar distribution. Species *''Arctomia delicatula'' *''Arctomia papuanorum'' *''Arctomia teretiuscula'' – China *''Arctomia uviformis'' Molecular phylogenetic evidence revealed inappropriate classifications for two species once placed in this genus, ''A. insignis'' and ''A. borbonica'' ; they were formally transferred to the genus ''Gabura'' in 2020. ''Arctomia fascicularis'' was confirmed to belong to ''Gabura'', a generic placement originally proposed by Per Magnus Jørgensen in 2014.

Theodor Magnus Fries
Theodor "Thore" Magnus Fries (28 October 1832 – 29 March 1913), was a Swedish botanist, lichenologist, and Arctic explorer. He was the son of the mycologist Elias Fries. Following in his father's footsteps, Fries studied botany, obtaining his doctoral degree in 1857 at Uppsala. He is credited for introducing the term in a commentary about the genus lichen genus '' Stereocaulon'' in an 1858 publication. He became a member of the Royal Swedish Academy of Sciences in 1865 and professor of botany and applied economics at Uppsala in 1877.Jorgensen, Per Magnus. 2001. Th. M.

Circumpolar Distribution
A circumpolar distribution is any range of a taxon that occurs over a wide range of longitudes but only at high latitudes; such a range therefore extends all the way around either the North Pole or the South Pole. Taxa that are also found in isolated high-mountain environments further from the poles are said to have arctic–alpine distributions. Animals with circumpolar distributions include the reindeer, polar bear, Arctic fox, snowy owl, snow bunting, king eider, brent goose and long-tailed skua in the north, and the Weddell seal and Adélie penguin in the south. Plants with northern circumpolar distributions include ''Eutrema edwardsii'' (syn. ''Draba laevigata''), ''Saxifraga oppositifolia'', ''Persicaria vivipara'' and ''Honckenya peploides ''Honckenya peploides'', the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus ''Honckenya'' of the plant family Caryophyllaceae.

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Baeomycetales Genera
The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa. Taxonomy The family Baeomycetaceae was originally proposed by Barthélemy Charles Joseph Dumortier in 1829 (under the spelling ''Baeomyceae''); he included two genera, ''Baeomyces'' and ''Calicium''. Baeomycetaceae was initially classified in the Lecanorales, and Baeomycetaceae and Cladoniaceae were thought to be closely related, sharing a phylogenetic origin in Lecideaceae. It was transferred to the order Helotiales based on the structure of its ascus, which is similar to those in genus ''Leotia''. However, the Helotiales consists of mostly non-lichenised fungi. The first DNA studies conducted with ''Baeomyce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Per Magnus Jørgensen
Per Magnus Jørgensen (born 1944) is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen. He is known for his work on the lichen families Pannariaceae and Collemataceae. Jørgensen was awarded the Acharius Medal in 2021 for his lifetime contributions to lichenology. Biography Jørgensen was born in Stavanger, Norway, in 1944. He obtained his Candidatus realium from the University of Bergen in 1969, where Knut Fægri was his supervisor. In 1978, he earned a doctor philosophiae from University of Bergen, with a dissertation titled "The lichen family Pannariaceae in Europe". He was a student of prominent lichenologist Rolf Santesson; Gunnar Degelius was another early mentor. During his time as a student, he was recruited to work at the Botanical Garden in Bergen. A few years after receiving his doctorate, he was appointed Professor of Systematic Botany at the University of Bergen in 1982. He was known for delivering hi ...

Gabura
''Gabura'' is a genus of lichen-forming fungi in the family Arctomiaceae. Although it was originally circumscribed in 1763 by French botanist Michel Adanson, the name was nomen rejiciendum–it was "suppressed" against the conserved name '' Collema'', and for a long time considered a synonym of ''Arctomia''. In 2014, Per Magnus Jørgensen proposed to use the name ''Gabura'' for what was then known as ''Collema fasciculare''. The name was formally resurrected for use in 2020. ''Gabura'' has three species transferred from the genus ''Arctomia'' following molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Arctomiaceae
The Arctomiaceae are a family of lichenized fungi in the Ascomycota, class Baeomycetales. The family was named by Theodor Magnus Fries in 1861, with '' Arctomia'' as the type genus. Species in this family are found in arctic and subarctic habitats, usually associated with bryophytes. Classification The order Arctomiales was proposed by Soili Stenroos, Jolanta Miadlikowska, and François Lutzoni in 2014 to contain this family. In 2018, the class Lecanoromycetes was revised using a temporal approach that uses time-calibrated chronograms to define temporal bands for comparable ranks for orders and families. In this work, the orders Arctomiales, Hymeneliales, and Trapeliales were synonymized with Baeomycetales. In a subsequent review of the use of this method for biological classification of lichens, Robert Lücking Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
