Gloeoporus Dichrous
''Gloeoporus dichrous'' is a species of fungus in the family Irpicaceae. First described as ''Polyporus dichrous'' by Elias Magnus Fries in 1815, it was later transferred to the genus ''Gloeoporus'' by Italian mycologist Giacomo Bresadola in 1912. The variety ''G. dichrous'' var. ''niger'' (formerly known as ''Ceriporiopsis nigra'') was proposed in 2008 after molecular A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irpicaceae
The Irpicaceae are a family of mostly polypores and crust fungi in the order Polyporales. Taxonomy The family was circumscribed in 2003 by mycologists Viacheslav Spirin and Ivan Zmitrovich. The type genus is '' Irpex''. Later multi-gene phylogenetic analyses of the Polyporales supported the use of this family. In these analyses, Irpicaceae is a sister taxon to the Meruliaceae; these two families, as well as the Phanerochaetaceae, form the phlebioid clade. Description Irpicaceae has both polypore and crust fungi. They have a monomitic hyphal system, containing only generative hyphae that do not have clamp connections. Their spores are thin-walled, smooth, and translucent. Cystidia are often absent from the hymenium. More rarely, some species are dimitic and/or with cystidia and/or clamp-connections present; for example, ''Emmia'' and ''Irpex'' have cystidia, and there are clamp connections in ''Gloeoporus''. Irpicaceae fungi produce a white-rot, except for one brown-rot genus (' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Described In 1815
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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...

Giacomo Bresadola
Giacomo Bresadola ( Mezzana, Trento; often given as Giacopo) 14 February 1847 – Trento 9 June 1929) was an eminent Italian mycologist. Fungi he named include the deadly '' Lepiota helveola'' and ''Inocybe patouillardii'', though the latter is now known as '' Inosperma erubescens'' as this latter description predated Bresadola's by a year. He was a founding member of the ''Société mycologique de France'' (Mycology Society of France). Life Bresadola was born in 1847 into a farming family in Trent, then an Austrian possession. From a very early age, he showed an interest in botany. After attending elementary school at Mezzana, he was sent by his father to Cloz in the Val di Non at the age of nine to continue his studies with his uncle who was a priest. His uncle, however, considered him too rambunctious and quickly sent him home again. In 1857, his father moved to Montichiari in Brescia to become a bronze merchant. At twelve years of age, he left to study at the technical i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloeoporus
''Gloeoporus'' is a genus of crust fungi in the family Irpicaceae. The genus has a widespread distribution. Taxonomy ''Gloeoporus'' was created by French mycologist Camille Montagne in 1842 to contain the subtropical species ''Gloeoporus conchoides''. The fungus is now known as '' Gloeoporus thelephoroides''. The genus name combines the Ancient Greek words ("sticky") and ("pore"). Although traditionally classified in the family Meruliaceae, molecular phylogenetic analysis supports the placement of ''Gloeoporus '' in the Irpicaceae. A recent (2018) revision of the taxonomic status and generic limits of ''Gloeoporus'' using molecular phylogenetics revealed a polyphyletic genus, and the subsequent transfer of some species to '' Meruliopsis''. Description ''Gloeoporus'' fungi have pore surfaces featuring a pinkish white, cream, or orange to deep reddish colour. The pores are small. The texture of the fruit bodies surface is gelatinous when fresh, but becomes resinous and cartilag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bres
In Irish mythology, Bres (or Bress) was a king of the Tuatha Dé Danann. He is often referred to by the name Eochaid / Eochu Bres. He was an unpopular king, and favoured his Fomorian kin. Name ''Eochu Bres'' has been translated as "beautiful horseman." The scribes who wrote down the text of the Cath Maige Tuired record ''Bres'' as meaning 'beautiful', however, this may be a false etymology. The original meaning of ''Bres'' may have derived from a root meaning "fight," "blow," "effort," "uproar," or "din." Description In the ''Lebor Gabála'' and ''Cath Maige Tuired'', Bres is portrayed as beautiful to behold, yet harsh and inhospitable. However, the poem ''Carn Hui Neit'' from the ''dindsenchas'' praises Bres' "kindly" and "noble" character and calls him the "flower" of the Tuatha Dé Danann. There, the following flattering descriptions are provided for Bres: * gifted with excellences * master of love-spells * kindly friend * noble and fortunate * ornament of the host * with a v ...
