Clavaria Zollingeri
''Clavaria zollingeri'', commonly known as the violet coral or the magenta coral, is a widely distributed species of fungus. It produces striking tubular, purple to pinkish-violet fruit bodies that grow up to tall and wide. The extreme tips of the fragile, slender branches are usually rounded and brownish. A typical member of the clavarioid or club fungi, ''Clavaria zollingeri'' is saprobic, and so derives nutrients by breaking down organic matter. The fruit bodies are typically found growing on the ground in woodland litter, or in grasslands. Variations in branching and color can often be used to distinguish ''C. zollingeri'' from similarly colored coral fungi such as '' Alloclavaria purpurea'' and '' Clavulina amethystina'', although microscopy is required to reliably identify the latter species. Taxonomy and phylogeny The species was first described scientifically by French mycologist Joseph-Henri Léveillé in 1846. It was named after Swiss botanist Heinrich Zollinger ...

Joseph-Henri Léveillé
Joseph-Henri Léveillé (28 May 1796 – 3 February 1870) was a French physician and mycologist who was a native of Crux-la-Ville, in the department of Nièvre. Léveillé studied medicine and mycology at the University of Paris, and in 1824 received his medical doctorate. In his 1837 paper ''Sur le hymenium des champignons'', he provided an early, comprehensive description of the basidium and cystidium of basidiomycete fungi, and was able to establish the role that the basidium played in spore production. Also, he made important findings in regard to the true nature of individual members of the so-called genus "Sclerotium". Selected writings * ''Sur le hymenium des champignons'' (1837) * ''Memoire sur le genre Sclerotium'' (1843) * ''Considérations mycologiques, suivies d'une nouvelle classification des champignons'' (1846) * ''Iconographie des Champignons de Paulet'' (1855) Honours He is honoured in the naming of '' Leveillella'' in 1915, which is a genus of fungi in the As ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Genetic Similarity
Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. Populations with many similar alleles have small genetic distances. This indicates that they are closely related and have a recent common ancestor. Genetic distance is useful for reconstructing the history of populations, such as the multiple human expansions out of Africa. It is also used for understanding the origin of biodiversity. For example, the genetic distances between different breeds of domesticated animals are often investigated in order to determine which breeds should be protected to maintain genetic diversity. Biological foundation In the genome of an organism, each gene is located at a specific place called the locus for that gene. Allelic variations at these loci cause phenotypic variation within species (e.g. hair colour, eye colour). However, most alleles do not hav ...

Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Clavariaceae
The Clavariaceae are a family of fungi in the order Agaricales. Originally the family contained most of the clavarioid fungi (club and coral fungi), but in its current sense is more restricted, albeit with a greater diversity of basidiocarp (fruit body) forms. Basidiocarps are variously clavarioid or agaricoid (mushroom-shaped), less commonly corticioid (effused, crust-like) or hydnoid (with pendant spines). Taxonomy History Clavariaceae was originally circumscribed (as "Clavariae") by French botanist and mycologist François Fulgis Chevallier in 1826. It was one of five families (along with the Agaricaceae, Hydnaceae, Polyporaceae, and Thelephoraceae) that Elias Fries used to divide the Agaricales and Aphyllophorales in his influential work '' Systema Mycologicum''. The family served as a convenient placement for all genera containing species with superficially similar club or coral-like fruitbodies. It was first M.A. Donk and later E.J.H. Corner who realized that, in this br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Molecular Phylogenetics
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.

Clavaria Vermicularis
''Clavaria fragilis'', commonly known as fairy fingers, white worm coral, or white spindles, is a species of fungus in the family Clavariaceae. It is synonymous with ''Clavaria vermicularis''. The fungus is the type species of the genus ''Clavaria'' and is a typical member of the clavarioid or club fungi. It produces tubular, unbranched, white basidiocarps (fruit bodies) that typically grow in clusters. The fruit bodies can reach dimensions of tall by thick. ''Clavaria fragilis'' is a saprobic species, growing in woodland litter or in old, unimproved grassland. It is widespread throughout temperate regions in the Northern Hemisphere, but has also been reported from Australia and South Africa. The fungus is edible, but insubstantial and flavorless. There are several other small white coral-like fungi with which ''C. fragilis'' may be confused. History and taxonomy ''Clavaria fragilis'' was originally described from Denmark in 1790 by Danish naturalist and mycologist The ...

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.
