Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual reproduction, sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are Asexual reproduction, asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, yeast#Beer, brewers' and bakers' yeast, Xylaria, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (containing all of the descendants of a common ancestor). Previously placed in the Basidiomycota along with asexual species from other fungal taxa, asexual (or Teleomorph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sordariomycetes
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota). It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in arthropods and mammals. The name Sordariomycetes is derived from the Latin ''sordes'' (filth) because some species grow in animal feces, though growth habits vary widely across the class. In 2013, it consisted of 3 subclasses, 12 orders, 600 genera and 3000 species, Then by 2015, it had 3 subclasses, 28 orders, 90 families and 1344 genera. This has increased to 4 subclasses and 54 orders in 2020. It then increased to 6 subclasses and 54 orders in 2023. In May 2023, the GBIF listed 26,295 species in Sordariomycetes. Sordariomycetes generally produce their asci in perithecial fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypocreomycetidae
Hypocreomycetidae is a subclass of sac fungi. It is a highly diverse group of fungi with species from various habitats. This subclass has been reported as pathogenic, endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous (animal dung) and insect fungi from aquatic and terrestrial habitats. The members of Hypocreomycetidae have light colored perithecia, non-amyloid or amyloid ascal rings, or those which lack apical rings and most taxa lack true paraphyses (Zhang et al. 2006). Hypocreomycetidae was established by Eriksson and Winka (1997) based on morphology and a single gene ( SSU) phylogenetic analysis. The subclasses of Sordariomycetes was expanded from three to six, when Eriksson & Winka (1997) introduced ''Hypocreomycetidae'', '' Sordariomycetidae'' and '' Xylariomycetidae'' based on morphology and nrDNA sequence data. The crown and stem ages of Hypocreomycetidae are 290 MYA and 302 331 MYA, respectively. Within Sordariomycetes, Savo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microascales
The Microascales are an order of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. This is a relatively small order of mostly saprobic fungi that live in soil, rotting vegetation and dung. Some species are plant pathogens, such as '' Ceratocystis fimbriata'', transmitted by beetles to living trees and causing cacao wilt and many other economically important diseases. Species in the genus '' Pseudallescheria'' (family Microascaceae) are pathogenic to humans The order was circumscribed in 1980. Wijayawardene et al. in 2020 added more families and genera to the order. Description The Microascales are characterized by a lack of stroma, black perithecial ascomata with long necks or rarely with cleistothecial ascomata that lack paraphyses. They have roughly spherical and short-lived asci that develop singly or in chains. Nonseptate, colorless ascospore In fungi, an ascospore is the sexual spore formed inside an ascus—the sac-like cell that defines the division ...

Microascaceae
The Microascaceae are a family of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. The family was published by David Malloch in 1970, an emended description based on Everet Stanley Luttrell's original 1951 publication. Family was updated in 2020. Description Microascaceae species have spherical to irregularly shaped, darkly colored fruit bodies. They are usually hairy and rarely smooth. The smooth spores are reddish brown to copper colored, one-celled, and have a germ pore at one or both ends. Asci can occur singly or in chains. Genera As accepted by Wijayawardene et al. 2020 (with number of species); *'' Acaulium'' (4) *'' Brachyconidiellopsis'' (1) *'' Canariomyces'' (3) *'' Cephalotrichum'' (37) - anamorph *'' Doratomyces'' (3) *'' Echinobotryum'' (2) *'' Enterocarpus'' (2) *'' Fairmania'' (1) *'' Gamsia'' (5) *'' Kernia'' (14) *'' Lomentospora'' (1) *'' Lophotrichus'' (8) *'' Microascus'' (60) *'' Parascedosporium'' (2) *'' Petriella'' (8) ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecu ...

Julius Nieuwland
Julius Aloysius Arthur Nieuwland, CSC, (14 February 1878 – 11 June 1936) was a Belgian-born Holy Cross priest and professor of chemistry and botany at the University of Notre Dame, Indiana. He is known for his contributions to acetylene research and its use as the basis for one type of synthetic rubber, which eventually led to the invention of neoprene by DuPont. Life and work Nieuwland's parents emigrated from Hansbeke, Belgium in 1880 to South Bend, Indiana. As a young man, Nieuwland enrolled at the University of Notre Dame, where he studied Latin and Greek and received his undergraduate degree in 1899. He soon after began studies for the priesthood. Ordained in 1903, Nieuwland attended graduate school at The Catholic University of America, where he studied botany and chemistry. During his doctoral studies into the chemistry of acetylene, he discovered the chemical compound lewisite, which would later gain fame as a chemical warfare agent. Nieuwland had to be hospi ...
