Foliose Lichen
Foliose lichen is one of the morphological classes of lichens, which are complex organisms that arise from the symbiotic relationship between fungi and a photosynthetic partner, typically algae. This partnership allows lichen to live in diverse climates that can range from cold, dry mountains to wet, warm valleys. Lichens develop quite slowly with recorded growth rates of 0.01–27mm/year depending on the species. Their lifespan averages between 30 and 60 years. Lichens have a main body part called the thallus, which is composed of hyphae, and houses the cortex and medulla. The cortex contains the photosynthetic cells while the medulla allows for gas exchange and makes up the bulk of the lichen's thallus. There are three main types of lichens: crustose, foliose, and fruticose. Foliose lichen are characterised by flattened leafy thalli, and an upper and lower cortex. Many have numerous layers, which are stratified, and aid in identifying different types. Foliose lichens attach to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parmeliaceae
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.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Zahlbruckner
Alexander Zahlbruckner (31 May 1860, Svätý Jur – 1938, Vienna) was an Austrian- Hungarian botanist who specialized in the study of lichens. Johann Babtist Zahlbruckner, an earlier Austrian botanist, was his grandfather. From 1878 to 1883 he studied at the University of Vienna, where his instructors included Anton Kerner von Marilaun and Julius Wiesner. Afterwards, he served as a voluntary assistant to Günther Beck von Mannagetta und Lerchenau at the Naturhistorisches Museum in Vienna, where he later attained the titles of assistant curator (from 1897), curator (from 1899) and head curator (from 1912). From 1918 until his retirement in 1922, he was director of the museum's botany department. From 1920, he was member of the Hungarian Academy of Sciences In retirement, he continued his studies in the field of lichenology.

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] |

Chicita Frances Culberson (born Chicita Frances Forman, November 1, 1931 in Philadelphia, Pennsylvania) is an American lichenologist. Education She graduated with a B.S. from the University of Cincinnati in 1953, where she also met her future husband, Bill Culberson. In 1954, Received an M.S. from the University of Wisconsin in 1954 and in 1959 received a Ph.D. from Duke University.

Cetrelia
''Cetrelia'' is a genus of leafy lichens in the large family Parmeliaceae. They are commonly known as sea-storm lichens, alluding to the wavy appearance of their lobes. The name of the genus, circumscribed in 1968 by the husband and wife lichenologists William and Chicita Culberson, alludes to the former placement of these species in the genera '' Cetraria'' and '' Parmelia''. The main characteristics of the genus are the broad, rounded lobes of the greyish-green lichen body, and the presence of tiny pores in the outer surface (the cortex) that enable gas exchange. The lower surface of the lichen is brown to black with few root-like rhizines to act as holdfasts, resulting in a fairly loose attachment to the surface the lichen is on. Sexual reproductive structures are usually not present, so the physical characteristics used to distinguish between ''Cetrelia'' species include the presence or absence of asexual reproductive structures such as isidia, soredia, and ...

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] |
