Hodophilus Foetens
''Hodophilus'' is a genus of agarics (gilled fungi) in the family Clavariaceae. Basidiocarps (fruit bodies) are dull-coloured and have dry caps, rather distant, decurrent lamellae, white spores, and smooth, ringless stems. In Europe species are characteristic of old, unimproved grasslands (termed waxcap grasslands) which are a declining habitat, making them of conservation concern. Several species have a distinct odour of napthalene. Taxonomy History ''Hodophilus'' was described by French mycologist Roger Heim in 1957, but this was invalid because he did not include a Latin diagnosis for the genus, as was required by the rules of nomenclature at the time. The name ''Hodophilus'' was later (1958) validly published, but it was generally regarded as synonymous with the genus ''Camarophyllopsis''. Current Status Recent molecular research, based on cladistic analysis of DNA sequences, indicates that ''Hodophilus'' is monophyletic In cladistics for a group of organis ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

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 ...

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.

Camarophyllopsis
''Camarophyllopsis'' is a genus of agarics (gilled fungi) in the family Clavariaceae. Basidiocarps (fruit bodies) are dull-coloured and have dry caps, rather distant, decurrent lamellae, white spores, and smooth, ringless stems. In Europe species are characteristic of old, unimproved grasslands (termed waxcap grasslands) which are a declining habitat, making them of conservation concern. Taxonomy History ''Camarophyllopsis'' was circumscribed by Czech mycologist Josef Herink in 1958, with '' Camarophyllopsis schulzeri'' as the type and only species. Roger Heim had the year previously treated this group of species under the name ''Hodophilus'', but this was invalid because he did not include a Latin diagnosis for the genus, as was required by the rules of nomenclature at the time. Rolf Singer published ''Hygrotrama'' in March 1959 (with type species '' Hygrotrama dennisianum''), and the name ''Hodophilus'' (type species '' Hodophilus foetens'') was validly published in 1958.

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Validly Published Name (botany)
In botanical nomenclature, a validly published name is a name that meets the requirements in the ''International Code of Nomenclature for algae, fungi, and plants'' for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ''ICN'' as "designations". A validly published name may not satisfy all the requirements to be '' legitimate''. It is also not necessarily the correct name for a particular taxon and rank. Nevertheless, invalid names (''nomen invalidum'', ''nom. inval.'') are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason for this is that a taxonomist intends to write a ''magnum opus'' that provides an overview of the group, rather than a series of small papers. Another reason is that the code of nomenclature chang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Heim
Roger Heim (February 12, 1900 – September 17, 1979) was a French botanist specialising in mycology and tropical phytopathology. He was known for his studies describing the anatomy of the mushroom hymenium, the systematics and phylogeny of higher fungi (especially the related genera ''Lactarius'' and ''Russula'', the Russulales and ''Secotium''), the mycology of tropical fungi such as ''Termitomyces'', as well as ethnomycological work on hallucinogenic fungi, like ''Psilocybe'' and '' Stropharia''. In his career, he published over 560 articles, scientific reviews, and major works in fields like botany, chemistry, education, forestry, horticulture, liberal arts, medicine and zoology.Batra, L.R. (1980). "Professor Roger Heim". ''Mycologia'' 72(6): 1063–1065.
