Heterochaete
''Heterochaete'' is a genus of fungi in the order Auriculariales. Species produce effused, gelatinous, waxy, or leathery basidiocarps (fruit bodies) on wood, partly or wholly covered in small sterile spines or pegs. The presence of these sterile spines distinguishes the genus from ''Exidiopsis'', species of which are microscopically similar but have smooth basidiocarps. ''Heterochaete'' was monographed by Bodman in 1952 who accepted some 29 species worldwide, most of them from the tropics and subtropics. On the basis of morphological differences, Bodman considered the genus to be heterogeneous and this has been confirmed by molecular research, based on cladistic analysis of DNA sequences. As a result, several species previously placed in ''Heterochaete'' have now been referred to the genera '' Crystallodon'', '' Eichleriella'', '' Heteroradulum'', '' Hirneolina'', '' Metulochaete'', and ''Tremellochaete''. DNA research has also indicated that the type species In zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tremellochaete
''Tremellochaete'' is a genus of fungi in the family Auriculariaceae. Species produce pustular or lobed, effused, gelatinous basidiocarps (fruit bodies) on wood, typically covered in small sterile spines or pegs. Taxonomy The genus was originally created in 1964 by Estonian mycologist Ain Raitviir to accommodate ''Tremellochaete japonica'', a species that appeared morphologically intermediate between the older genera ''Exidia'' and '' Heterochaete''. ''Tremellochaete'' was subsequently treated as a synonym of ''Exidia'' by some authors until shown to be distinct as a result of molecular research, based on cladistic analysis of DNA sequences A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are us .... Several additional species have now been referred to ''Tremellochaete''. References Ex ...

Heteroradulum
''Heteroradulum'' is a genus of fungi in the order Auriculariales. Species produce effused, leathery basidiocarps (fruit bodies) on wood, often pinkish red and partly or wholly covered in small sterile spines. The genus was originally published in 1917 by American mycologist Curtis Gates Lloyd under the facetious pseudonym "McGinty", rendering the name invalid. It was validated a century later to accommodate a group of species formerly placed in the genera '' Eichleriella'' or ''Heterochaete ''Heterochaete'' is a genus of fungi in the order Auriculariales.

Eichleriella
''Eichleriella'' is a genus of fungi in the order Auriculariales. Species produce effused or cupulate, waxy to leathery basidiocarps (fruit bodies) on wood, with a smooth to spiny surface. The genus contains some twelve species. Molecular research, based on cladistic analysis of DNA sequences, has redefined the genus, with some species now placed in ''Heteroradulum'' and others transferred to ''Eichleriella'' from ''Heterochaete''. ''Eichleriella'' was named by Italian mycologist Giacomo Bresadola in honour of Bogumił Eichler (1843 - 1905), Polish botanist Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek wo ... and mycologist.

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.

DNA Sequences
A nucleic acid sequence is a succession of bases signified by a series of a set of five different letters that indicate the order of nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence has capacity to represent information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as ''primary sequence''. Conversely, there is no parallel concept of secondary or tertiary sequence. Nucleotides Nucleic acids consis ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...

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.
