Loweomyces
''Loweomyces'' is a genus of six species of poroid fungi in the family Steccherinaceae (formerly placed in the Meruliaceae). Taxonomy It was originally circumscribed as a subgenus of ''Spongipellis'' by the Czech mycologists František Kotlaba and Zdeněk Pouzar in 1976. Swiss mycologist Walter Jülich promoted it to a genus segregate from ''Spongipellis'' in 1982, with two species: '' L. fractipes'' (the type), and '' L. wynneae''. Jülich thought the genus should be distinct from ''Spongipellis'' based on the larger basidia, the absence of skeletal hyphae, and smaller tubes. ''L. fractipes'' and ''L. wynneae'' have had their generic positions confirmed with molecular phylogenetics, and both group in the "residual polyploid clade", one of four main lineages of the Polyporales. The genus is named in honour of American mycologist and polypore specialist Josiah Lincoln Lowe. Description ''Loweomyces'' is distinguished by the ease of spore germination in g ...

Loweomyces Fractipes
''Loweomyces fractipes'' is a species of polypore, poroid fungus in the family Steccherinaceae, and the type species of the genus ''Loweomyces''. It is a widely distributed species, found in North America, Europe, Central America, South America, and Korea. Taxonomy The fungus was originally species description, described in 1872 as ''Polypores fractipes'' by Miles Berkeley and Moses Ashley Curtis. The type specimens had been sent to Berkeley by American botanist Henry William Ravenel. It has been transferred to many different polypore genera in its taxonomic history. William Alphonso Murrill, William Murrill moved it to ''Grifola'' in 1904, while it was later transferred to ''Abortiporus'' (Bondartsev, 1959), ''Heteroporus'' (Fidalgo, 1969), and ''Spongipellis'' (Kotl., Kotlaba & Pouzar, 1976). In 1982, Walter Jülich transferred it to ''Loweomyces'', originally a subgenus of ''Spongipellis'' but elevated to generic status by Jülich. Heterotypic synonyms (having different type ( ...

Steccherinaceae
The Steccherinaceae are a family of about 200 species of fungi in the order Polyporales. It includes crust-like, toothed, and poroid species that cause a white rot in dead wood. Taxonomy The family was circumscribed by Czech mycologist Erast Parmasto in 1968. Parmasto's original concept included species that are today classified in the Agaricales, Hymenochaetales, Polyporales, and Russulales. A large-scale molecular study published in 2012 by Otto Miettinen and colleagues redefined the limits of the Steccherinaceae to include most species of the poroid and hydnoid genera ''Antrodiella'', ''Junghuhnia'', and ''Steccherinum'', as well as members of 12 other hydnoid and poroid genera. These genera were traditionally classified in the families Phanerochaetaceae, Polyporaceae, and Meruliaceae. They commented: "we see the need for at least 30 monophyletic, morphologically distinguishable genera. These include no fewer than 15 new genera for both polypores and hydnoid fungi, and reviv ...

Josiah Lincoln Lowe
Josiah Lincoln Lowe (13 February 1905 – 30 April 1997) was an American mycologist who specialized in the study of polypores. Lowe was born in Hopewell, New Jersey, where he attended primary school and high school. In 1927, he graduated with a Bachelor of Science degree from Syracuse University in Syracuse, New York, and he received a doctorate from the University of Michigan in 1938, with Calvin H. Kauffman and Edwin Butterworth Mains as his main academic supervisors. His doctoral thesis was entitled ''The genus ''Lecidea'' in the Adirondack Mountains of New York''. That year, he started his academic career at the College of Forestry, a position he held for almost 40 years. He retired in 1975 and became an emeritus professor. Lowe was the president of the Mycological Society of America in 1960. In the 1980s, Lowe was diagnosed with Alzheimer's disease; he died in Syracuse. Several fungal taxa have been named in his honor, including the species ''Leptoporus lowei'' Pilát, ''Lind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 motility, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multic ...

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. History The theoretical ...
