Cuphophyllus Canescens
''Cuphophyllus canescens'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae, known from North America. In its wide sense (including the recently separated '' C. atlanticus'') it has been assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy The species was first described from North Carolina in 1942 by American mycologists Alexander H. Smith and Lexemuel Ray Hesler as ''Hygrophorus canescens''. It was transferred to the genus ''Cuphophyllus'' by French mycologist Marcel Bon in 1990, at which time it was thought also to occur in northern Europe. As a result of molecular research, based on cladistic analysis of DNA sequences, ''Cuphophyllus canescens'' has, however, been found to be restricted to North America. Similar species ''Cuphophyllus atlanticus ''Cuphophyllus atlanticus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae.

Fungi Of North America
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Fungi By Conservation Status
, the International Union for Conservation of Nature (IUCN) has evaluated the conservation status of 280 fungus species. Previously in the 2017-3 release, the IUCN evaluated the conservation status of 56 fungus species. One subspecies, that of ''Pleurotus nebrodensis'', also was evaluated but has since been removed. At the time no subpopulations were evaluated. , the New Zealand Threat Classification System listed 1512 species and 39 subspecies of fungi, with 65 species considered Threatened.

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.

Cuphophyllus
''Cuphophyllus'' is a genus of agaric fungi in the family Hygrophoraceae. ''Cuphophyllus'' species belong to a group known as waxcaps in English, sometimes also waxy caps in North America or waxgills in New Zealand. In Europe, ''Cuphophyllus'' species are typical of waxcap grasslands, a declining habitat due to changing agricultural practices. As a result, four species, '' Cuphophyllus atlanticus'' (as '' C. canescens''), '' C. colemannianus'', '' C. lacmus'', and '' C. lepidopus'' are of global conservation concern and are listed as "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy History The genus was described by French mycologist Marcel Bon in 1985, though it was subsequently synonymized with ''Hygrocybe'' by some authorities. ''Cuphophyllus'' species have sometimes been referred to the genus ''Camarophyllus'' ( Fr.) P.Kumm., but, as argued by Donk (1962), the type species of ''Camarophyllus'' must be ''Agaricus camarophyllus'' Alb. & Schwein. the speci ...

Mycologist
Mycology is the branch of biology concerned with the study of fungus, fungi, including their genetics, genetic and biochemistry, biochemical properties, their Taxonomy (biology), taxonomy and ethnomycology, their use to humans, including as a source for tinder, traditional medicine, Edible mushroom, food, and entheogens, as well as their dangers, such as poison, toxicity or fungal infection, infection. A biologist specializing in mycology is called a mycologist. Mycology branches into the field of phytopathology, the study of plant diseases, and the two disciplines remain closely related because the vast majority of plant pathogens are fungi. Overview Historically, mycology was a branch of botany because, although fungi are evolutionarily more closely related to animals than to plants, this was not recognized until a few decades ago. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz ...

Marcel Bon
Marcel Bon (17 March 1925 – 11 May 2014)http://fmbds.org/wp-content/uploads/2014/06/CAFAM-2014-CR-complet.pdf was one of France's best known field mycologists. He was born in Picardy in 1925 and came to mycology through general botany, and pharmacology. He lived at Saint-Valery-sur-Somme, a quaint little town on the mouth of the river Somme, in Picardy, Northern France, which was a former artists' and writers' retreat, and is now a popular tourist town. In 1987, along with two artists (John Wilkinson, and Denys Ovenden) he produced a comprehensive field guide for mycologists, ''The Mushrooms and Toadstools of Britain and North-western Europe''. His other skills were as a pianist, an artist, and a skier. Bibliography *''The Mushrooms and Toadstools of Britain and North Western Europe'', Bon M., (1987) pub.

Cuphophyllus Atlanticus
''Cuphophyllus atlanticus'' is a species of agaric (gilled mushroom) in the family Hygrophoraceae. Until recently (2021), the species was considered to be conspecific with the North American '' Cuphophyllus canescens'', but DNA sequencing has shown that it is distinct. As ''C. canescens'', it has been given the recommended English name of felted waxcap in the United Kingdom. ''Cuphophyllus atlanticus'' has a European and North American distribution, occurring in Europe mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in ''C. canescens'' (including ''C. atlanticus'') being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. Taxonomy The species was first described from Norway in 2021 as a result of molecular research, based on cladistic analysis of DNA sequences. Previously, European specimens had been referred to the similar '' Cuphophyllus canescens'', but the latter species appears to be confined to North America. ...
