Agyrium
''Agyrium'' is a genus of saprophytic fungi in the family Agyriaceae. It probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi. Taxonomy ''Agyrium'' was first proposed by Elias Magnus Fries in his 1821 work ''Systema Mycologicum'', although the name was not published validly as a type species was not indicated; Fries published the name validly a year later in the second volume of the same work. The species ''Agyrium rufum'' was assigned as the type by Frederic Clements and Cornelius Lott Shear in 1931. Description Characteristics of genus ''Agyrium'' include the following: a poorly developed thallus that is immersed in its substrate; ascomata in the form of an apothecium with a reduced ring-shaped exciple (the layer surrounding the hymenium that sometimes develops into a distinct margin); paraphyses that are highly branched; and ascospores that are ellipsoid and thin-walled. The mycelia of ''Agyrium'' fungi, although not strict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agyriaceae
The Agyriaceae are a family of lichenized fungi in the order Pertusariales. It contains two genera: ''Agyrium'', and '' Miltidea''. The family was circumscribed by August Carl Joseph Corda in 1838. In 2018, using a molecular phylogenetic 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 ... approach coupled with a technique known as "temporal banding", Kraichak and colleagues proposed to fold the family Miltideaceae into the Agyriaceae. A close genetic relationship between these two families had previously been noted. The proposal to subsume Miltideaceae into the Agyriaceae was accepted in a later critical analysis of the temporal banding technique for fungal classification.

Skyttella Mulleri
''Skyttella'' is a genus of lichenicolous fungi in the family Cordieritidaceae. It contains two species. The genus was circumscribed in 1988 by David Leslie Hawksworth and Rolf Santesson, with ''Skyttella mulleri'' assigned as the type species. This species, which parasitizes the lobes of foliose lichens in the genus ''Peltigera'', was previously classified in the genus '' Phacopsis''. '' Skyttella stictae'', an Ecuadorian species that grows on ''Sticta ''Sticta'' is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. ''Sticta'' ...'', was added to the genus in 2017. The genus name of ''Skyttella'' is in honour of Mogens Skytte Christiansen (1918 - 1996), a Danish botanist (interested in Microbiology, Mycology an Lichenology), and also a botanical illustrator.

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.

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffballs, ...

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North Pole. Owing to Earth's axial tilt of 23.439281°, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer lasts from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation. Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis e ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''.
