Asahinea Scholanderi
''Asahinea'' is a genus of lichenized fungi in the family Parmeliaceae. The genus has a widespread circumpolar distribution, and contains three species. The genus was circumscribed by the husband and wife lichenologist team William and Chicita F. Culberson in 1965, with '' Asahinea chrysantha'' as the type species. The genus name honours Japanese lichenologist Yasuhiko Asahina. See also *List of Parmeliaceae genera The Parmeliaceae is a large and diverse family of Lecanoromycetes.

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 ...

Lichen Genera
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. 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 ( |
List Of Parmeliaceae Genera
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: ''Xanthoparmelia'' ( 822 species), ''Usnea'' (355 species), ''Parmotrema'' ( 255 species), and ''Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often ''Trebouxia'' spp., but '' Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

Yasuhiko Asahina
Yasuhiko Asahina (朝比奈泰彦 ''Asahina Yasuhiko''; April 16, 1881 – June 30, 1975) was a Japanese chemist and lichenologist. Early life During his childhood, Asahina developed an interest in plants. In 1902, he enrolled in the School of Pharmacy at Tokyo Imperial University, from which he graduated in 1905. Asahina stayed at the university to research the chemical principles of Chinese traditional medicine under Junichiro Shimoyama. His first paper on styracitol isolation from ''Styrax obassia'' was published in 1907. In 1909, Asahina travelled to Zurich to study phytochemistry under Richard Willstätter. He continued his research on chlorophyll until 1912, when he moved to Berlin. He spent three months in Germany working in the laboratory of Professor Emil Fischer on a styracitol experiment.Shibata, S. (2000).

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

William Louis Culberson
William Louis "Bill" Culberson (April 5, 1929 in Indianapolis, Indiana – February 8, 2003 in Durham, North Carolina) was an American lichenologist. Professional history Culberson earned his bachelor's degree at the University of Cincinnati, where he was influenced by E. Lucy Braun; he subsequently attended the University of Paris and the University of Wisconsin–Madison. In 1955, Culberson joined the botany department at Duke University; he subsequently managed Duke's acquisition of the lichen-centric herbaria of Julien Harmand and Johan Havaas. He served as the Hugo L. Blomquist Professor. In 2010, the lichen collection was officially named the William Louis & Chicita F. Culberson Lichen Herbarium & Library. He served as president of the Botanical Society of America and the American Bryological and Lichenological Society and as director of the Sarah P. Duke Gardens. He was the first editor-in-chief of the journal ''Systematic Botany''. In 1992, he became one of the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Other common names include sea chickweed, sea pimpernal, sea-beach sandwor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
