Phialemonium Curvatum
''Phialemonium curvatum'' is a pathogenic fungus in the phylum Ascomycota. The genus was created to accommodate taxa intermediate to ''Acremonium'' and ''Phialophora''. This genus is characterized by its abundance of adelophialides and few discrete phialides with no signs of collarettes. Specifically, ''P. curvatum'' is characterized by its grayish white colonies and its allantoid conidia. ''Phialemonium curvatum'' is typically found in a variety of environments including air, soil, industrial water and sewage. Furthermore, ''P. curvatum'' affects mainly immunocompromised and is rarely seen in immunocompetent people. The species has been known to cause peritonitis, endocarditis, endovascular infections, osteomyelitis as well as cutaneous infections of wounds and burns. Description and identification ''Phialemonium curvatum'' was first described by W. Gans et McGinnis in 1983. It is noted as being pigmented although it lacks dark pigmentation. The colony appearance is flat and g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phialemonium Obovatum
''Phialemonium obovatum'' is a saprotrophic filamentous fungus able to cause opportunistic infections in humans with weakened immune systems. ''P. obovatum'' is widespread throughout the environment, occurring commonly in sewage, soil, air and water. Walter Gams and Michael McGinnis described the genus ''Phialemonium'' to accommodate species intermediate between the genera ''Acremonium'' and ''Phialophora.'' Currently, three species of ''Phialemonium'' are recognized of which ''P. obovatum'' is the only one to produce greenish colonies and obovate conidia. It has been investigated as one of several microfungi with potential use in the accelerated aging of wine. Growth and morphology In culture, colonies of ''P. obovatum'' begin as white or off-white in colour becoming pale green and centrally darkened with age. The green pigments diffuse into the growth medium ultimately becoming blackish-green in colour. Although the hyphae of the fungus are typically colourless (hyaline), the ...

Cephalothecaceae
The Cephalothecaceae are a family of fungi in the class Sordariomycetes. The family was circumscribed in 1917 by Austrian naturalist Franz Xaver Rudolf von Höhnel. Species in this family are saprobic, often growing on rotten wood or on other fungi. They are known to be distributed in northern temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout t ... regions.

Dematiaceous
“Black yeasts”, sometimes also black fungi, dematiaceous fungi, microcolonial fungi or meristematic fungi is a diverse group of slow-growing microfungi which reproduce mostly asexually (fungi imperfecti). Only few genera reproduce by budding cells, while in others hyphal or meristematic (isodiametric) reproduction is preponderant. Black yeasts share some distinctive characteristics, in particular a dark colouration ( melanisation) of their cell wall. Morphological plasticity, incrustation of the cell wall with melanins and presence of other protective substances like carotenoids and mycosporines represent passive physiological adaptations which enable black fungi to be highly resistant against environmental stresses. The term " polyextremotolerance" has been introduced to describe this phenotype, a good example of which is the species ''Aureobasidium pullulans''. Presence of 1,8-dihydroxynaphthalene melanin in the cell wall confers to the microfungi their characteristic oliva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phialophora
''Phialophora'' is a form genus of fungus with short conidiophores, sometimes reduced to phialides; their conidia are unicellular. They may be parasites (including on humans), or saprophytic (including on apples). Genetic analysis of ''Phialophora'' shows that it is a paraphyletic grouping. The conidia are produced from a flask shaped phialide. Mature, spherical, to oval conidia are extruded from phialides and usually accumulate around it. Some members of ''Phialophora'' are involved in symbiotic relationships with leafcutter ants where they grow on the cuticle of the ants and fulfill a saprophytic Saprotrophic nutrition or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi ( ... role that aids in the fungal gardening on which the ants rely. References External links * Eurotiomycetes Eurotiomyce ...

Acremonium
''Acremonium'' is a genus of fungi in the family Hypocreaceae. It used to be known as ''Cephalosporium''. Description ''Acremonium'' species are usually slow-growing and are initially compact and moist. Their hyphae are fine and hyaline, and produce mostly simple phialides. Their conidia are usually one-celled (i.e. ameroconidia), hyaline or pigmented, globose to cylindrical, and mostly aggregated in slimy heads at the apex of each phialide. ''Epichloë'' species are closely related and were once included in ''Acremonium'', but were later split off into a new genus ''Neotyphodium'', which has now been restructured within the genus ''Epichloë''. Clinical significance The genus ''Acremonium'' contains about 100 species, of which most are saprophytic, being isolated from dead plant material and soil. Many species are recognized as opportunistic pathogens of man and animals, causing eumycetoma, onychomycosis, and hyalohyphomycosis. Infections of humans by fungi of this genus are ...

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 ...

Fungus
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] |
