Uncobasidium
''Uncobasidium'' is a genus of two species of crust fungi in the Meruliaceae family . The genus was circumscribed by mycologists Kurt Hjorstam and Leif Ryvarden in 1978 with the European fungus '' U. luteolum'' as the type species. The South American species '' U. roseocremeum'' was added to the genus in 2012. The distinguishing feature of ''Uncobasidium'' is the basal hook in the basidium. Description ''Uncobasidium'' forms a crust-like fruit body, which is spread out on the surface of the substrate. Its texture is softly membranous or byssoid (as if made of fibers). The hyphal system is monomitic, meaning it contains only generative hyphae. Individual hyphae are distinct when viewed with microscopy, and they range from thin to becoming thick walled, with clamp connections. The hyphae of the subiculum are usually straight and of uniform diameter. In contrast, the hyphae of the subhymenium are twisty and sometimes strongly bent. The basidia (pleurobasidia) are rough ...

Uncobasidium Luteolum
''Uncobasidium luteolum'' is a species of crust fungus in the family Meruliaceae, and the type species of genus ''Uncobasidium''. The holotype was collected in Øvre Dividal National Park, in Målselv Municipality (Norway), where it was growing on '' Salix''. The fungus has a monomitic hyphal system, with individual hyphae measuring 2.5–4 μm and having a clamp connection and oily refractive contents. The basidia are four- sterigmate, measure 30–50 by 8 μm, and feature a hook-shaped protuberance. Its spores are ellipsoid An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation.

Uncobasidium Roseocremeum
''Uncobasidium roseocremeum'' is a species of crust fungus in the family Meruliaceae. Found in South America, it was described as a new species in 2012 by mycologists Sergio Gorjón, Alina Greslebin, and Mario Rajchenberg. The holotype was collected in Nahuel Huapi National Park, Argentina, where it was found growing on the bark of a living tree of '' Saxegothaea conspicua''. The specific epithet ''roseocremeum'' refers to the colour of the fruit body— cream with pinkish tints. Microscopic features of the fungus include its basidia that have two sterigma and lateral protuberances, encrusted hyphae that resemble paraphyses Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fe ..., and spherical spores. References Meruliaceae Fungi described in 2012 Fungi of Argentina Fungu ...

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 ...

Fungi
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'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clamp Connections
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is a characteristic feature of Basidiomycetes fungi. It is created to ensure that each cell, or segment of hypha separated by septa (cross walls), receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types. It is used to maintain genetic variation within the hypha much like the mechanisms found in crozier (hook) during sexual reproduction. Formation Clamp connections are formed by the terminal hypha during elongation. Before the clamp connection is formed this terminal segment contains two nuclei. Once the terminal segment is long enough it begins to form the clamp connection. At the same time, each nucleus undergoes mitotic division to produce two daughter nuclei. As the clamp continues to develop it uptakes one of the daughter (green circle) nuclei and separates it from its sister nucleus. While this is occurring the remaining nuclei (o ...

Polyporales Genera
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). Many species within the order are saprotrophic, most of them wood-decay fungus, wood-rotters. Some genera, such as ''Ganoderma'' and ''Fomes'', contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important plant pathology, pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially Fungiculture, cultivated and marketed for use as food items or in traditional Chinese medicine. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota Basidiomycota () is one of two large divisions that, together with ...

Radulomyces Notabilis
''Radulomyces'' is a genus of crust fungi in the family Radulomycetaceae. The genus has a widespread distribution and contains 11 species. It was circumscribed by Danish botanist Mads Peter Christiansen in 1960, with '' Radulomyces confluens'' as the type species. This genus was formally considered to be part of the ''Pterulaceae'' family. A major reclassification of the ''Pterulaceae'' family occurred in 2020 and the genera ''Aphanobasidium'', ''Radulomyces'' and ''Radulotubus'' were moved to a new family, '' Radulomycetaceae'' by the mycologists Caio A.

Cerocorticium Calongei
''Cerocorticium'' is a genus of seven species of crust fungi in the family Meruliaceae. Taxonomy The genus was circumscribed by German mycologist Paul Christoph Hennings in 1900, as a member of the family Thelephoraceae. Hennings included two species, ''C. tjibodense'', and the type, ''C. bogoriense'', both collected on Java. Later analysis of the type specimens showed that these two fungi were in fact the same species, today known as '' C. molle''. Description The fruit bodies of ''Cerocorticium'' fungi are crust-like, and spread out on the substrate with a waxy texture. The spore-bearing surface is roughly even and light coloured. The hypha A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium.
