Leif Ryvarden
Leif Randulff Ryvarden (born 9 August 1935) is a Norwegian mycologist. Early life and education Leif Ryvarden was born in Bergen as a son of Einar Norberg Johansen (1900–1959) and Hjørdis Randulff (1912–1975). He finished his secondary education at Berg in 1954 and took basic military education from 1957 to 1958 and in 1956 he changed his last name from Johansen to Ryvarden. He studied chemistry at the Norwegian Institute of Technology. In 1961 he ran for election as chairman of Student Society in Trondheim, albeit unsuccessfully. In 1963, he graduated with the siv.ing. degree , and later majored in botany at the University of Oslo, taking a cand.real. degree. He also studied in London from 1971 to 1972, a stay that sparked his interest in mycology. Academic career Ryvarden conducted field work in about eighty countries, mostly in a tropical environment. From 1965 to 1966, he was employed as research assistant at the Norwegian Institute of Technology, from 1966 to 1972 as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 r ...

Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family. Taxonomy The family was formally circumscribed by English mycologist Carleton Rea in 1922, with ''Merulius'' as the type genus. He also included the genera ''Phlebia'', '' Coniophora'' (now placed in the Coniophoraceae), and ''Coniophorella'' (now considered a synonym of ''Coniophora''). His description of the Meruliaceae was as follows: "Hymenium spread over veins, anastomosing pores, or quite smooth; ''edge of veins or pores fertile.''" Several genera formerly classified in the Meruliaceae were moved to the family Steccherinaceae based on molecular evidence. Description Meruliaceae species are crust-like or polyporoid, and often have a waxy appearance when dry. Their hyphal systems are monomitic (containing only tightly arranged generative hyphae), and these hyphae have clamp connec ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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] |

Fungi Of Mexico
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] |
