Graphis Aptrootiana
''Allographa aptrootiana'' is a species of script lichen in the family Graphidaceae that is found in tropical Africa. It was formally described as a new species in 2014 by Dries Van den Broeck, Robert Lücking, and Damien Ertz. The type locality is Yaengo (Orientale Province, Democratic Republic of the Congo; here it was found growing on the bark of an unidentified tree species in an evergreen forest. The lichen somewhat resembles ''Graphis tetralocularis'' in overall morphology, but unlike that species it has a completely carbonized (blackened) excipulum, and does not produce the secondary compound atranorin. The holotype specimen is parasitised with ''Etayoa trypethelii'', a widespread tropical lichenicolous fungus. The specific epithet ''aptrootiana'' honours André Aptroot, "in recognition of his many contributions to tropical lichenology". The taxon was transferred to ''Allographa ''Allographa'' is a genus of script lichens in the family Graphidaceae. It has nearly 200 ...

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 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atranorin
Atranorin is a chemical substance produced by some species of lichen. It is a secondary metabolite belonging to a group of compounds known as depsides. Atranorin has analgesic, anti-inflammatory, antibacterial, antifungal, cytotoxic, antioxidant, antiviral, and immunomodulatory properties. In rare cases, people can react allergic Allergies, also known as allergic diseases, refer a number of conditions caused by the hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic derm ... to atranorin. References Further reading * * * * Polyphenols Lichen products {{organic-compound-stub ...

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'' (''Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allographa
''Allographa'' is a genus of script lichens in the family Graphidaceae. It has nearly 200 species.

Taxon
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botanical Name
A botanical name is a formal scientific name conforming to the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the '' International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name '' Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichenicolous Fungus
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 classes and 19 orders Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization wherein the elements have the potential to be ranked a number o ...

Etayoa Trypethelii
''Etayoa'' is an ungulate of the family Carodniidae in the order Xenungulata that lived during the Early Eocene (~ 55 Ma) in northern South America. Etymology The genus of the type species ''Etayoa bacatensis'' was named by palaeontologist Carlos Villarroel after Fernando Etayo Serna, who contributed extensively to the paleontology and stratigraphy research in Colombia. The species epithet ''bacatensis'' refers to Bacatá,Villarroel, 1987 the name in Muysccubun for the main settlement of the southern Muisca Confederation; the name of which has been used for the current Colombian capital Bogotá, founded in a different location than the original Bacatá.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...
