Echinodiscus (fungus)
''Neoechinodiscus'' is a genus of two species of lichenicolous fungi with uncertain familial placement in the order Helotiales. Species: *'' Neoechinodiscus kozhevnikovii'' *'' Neoechinodiscus lesdainii'' These species used to be classified in ''Echinodiscus'', a genus proposed by Javier Etayo and Paul Diederich in 2000. Diederich subsequently discovered that the fungal use of the genus name was an illegitimate homonym, as it had already been used for a legume A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant.

Léon Vouaux
Léon Vouaux (1870-1914) was a French priest, philologist and lichenologist. He was executed by German forces in the second month of the First World War. The Académie française awarded him the Prix Saintour posthumously in 1915. Early life and education Vouaux was born 25 February 1870 in Baccarat, Meurthe-et-Moselle in Lorraine, France. He studied at seminaries in Pont-à-Mousson and Nancy and was ordained a priest in 1893. He then attended the University of Nancy from 1894 until 1898. Vouaux was awarded an Arts degree (''license dès-lettres'') in 1895 and in 1898 he passed the grammar aggregation competition (''licence l'agrégation de grammaire'') as a prelude to appointment to an academic post. Career He was appointed to the staff of the ecclesiastical college of Malgrange, near Nancy, where he taught literature and mathematics until his death. He was promoted to be a first grade teacher (''professeur de première''). He wrote in Greek and Latin and was able to trans ...

Neoechinodiscus Kozhevnikovii
''Neoechinodiscus kozhevnikovii'' is a species of lichenicolous (lichen-eating) fungus in the order Helotiales. It is known to occur in Russia, Austria, and Switzerland, where it grows parasitically on lichens in genus ''Cetraria''. Taxonomy The fungus was formally described as new to science in 2009 by lichenologist Mikhail Zhurbenko, who placed it in the genus ''Echinodiscus''. The type specimen was collected by the author at the head of Kaskasnyunjok Creek (in the Khibiny Mountains, Murmansk Oblast); there, at an altitude of , the fungus was found growing on ''Cetraria islandica'', which itself was growing on lichen tundra. The species epithet ''kozhevnikovii'' honours the late Dr. Yurii Kozhevnikov, a friend of the author and a "devoted explorer of Arctic wildlife". The taxon was transferred to the genus '' Neoechinodiscus'' after it was discovered that ''Echinodiscus'' was an illegitimate homonym that had already been used for other taxa. The replacement name ''Neoe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Lichenicolous Fungi
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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Helotiales
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. , the order is estimated to contain 30 accepted families, 519 genera, and 6266 species. Helotiales is the largest order of non-stromatic discomycetes that usually, but not always, have brightly coloured apothecia. Many members of the family have obviously cup-shaped ascomata with little or no stipes. They are usually found fruiting on coarse or large wood debris as well as on other organic matter. Part of these discomycetes are limited to a specific host range, this goes as far as to not just being limited to one particular plant, additionally some species need a particular part of that plant. Description *Helotiales is distinguished by its disc or cup-shaped apothecia. *Its asci are only slightly thickened in contrast to other Leotiomy ...

Homonym (biology)
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is "valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :*Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :* Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants (IC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legume
A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, soybeans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces (opens along a seam) on two sides. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules. For that reason, they play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and green peas, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatom
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...
