Farrowia is a genus of fungi within the Chaetomiaceae family. [1]
In 1975, Hawksworth suggested a novel genus for F. seminuda, F. longicola, and F. malaysiensis. [2] These species were distinguished from other Chaetomium species by their long-necked ascomata and production of anamorphs similar to Botryotrichum . [2] However, this categorization has been controversial since its inception. [3] [4] [5] In 2001, a molecular phylogenetic study using rRNA sequence data did not support the separation of Farrowia and Chaetomium. [6]
Widden, in 1986, suggested that Farrowia seminuda and Botryotrichum piluliferum are the teleomorph and anamorph of the same organism based on their preference for coniferous soils and visual indistinguishability. [7]
Perithecia are subglobose (imperfectly spherical), with straight, unbranched lateral and terminal hairs. [2] The terminal hairs fuse to form a neck-like structure, potentially rudimentary. [2] Pedestal-like rhizoidal bases are usually present. Farrowia forms asci which are clavate (club-shaped) and deliquesce before ascospores mature. [2] The ascospores are lemoniform (lemon-shaped), biapiculate, and are not ornamented. [2] F. malaysiensiensis is reported having a longer neck than the other two species in this genus. [3] [8]
In media cultures, reddish brown pigments are produced only in the presence of contaminants. [2]
Species are widespread across tropical and temperate areas. [7] [8] It is most commonly found in soil, although F. longicola has been found in leaf litter [5] and freshwater. [8]
Novel interleukin inhibitors were isolated from Farrowia broths in 2003. [9] These compounds were named EI-1941-1 and EI-1941-2. The enzymes they specifically inhibit are elastase and cathepsin B. [9] EI-1941-2 is degraded by the presence of cysteine, but EI-1941-1 is not. [9] Further study of these ICE inhibitors could lead to new synthetic anti-inflammatory agents.
Venturia inaequalis is an ascomycete fungus that causes the apple scab disease.
Chaetomium is a genus of fungi in the Chaetomiaceae family. It is a dematiaceous (dark-walled) mold normally found in soil, air, cellulose and plant debris. According to the Dictionary of the Fungi, there are about 95 species in the widespread genus.
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 are pathogenic to humans The order was circumscribed in 1980. Wijayawardene et al. in 2020 added more families and genera to the order.
Bovicornua is a fungal genus in the family Halosphaeriaceae. It is a monotypic genus, containing the single species Bovicornua intricata, a marine fungus formally described as new to science in 1993 by mycologists Jørgen Koch and E.B. Gareth Jones. Bovicornua is distinguished from Ceriosporopsis by the structural complexity of its ascospores.
Crinigera is a genus of fungi in the division Ascomycota. The relationship of this taxon to other taxa within the phylum is unknown, and it has not yet been placed with certainty into any class, order, or family. This is a monotypic genus, containing the single species Crinigera maritima. Crinigera maritima is a marine ascomycota fungus species with characteristic appendaged cleistothecia and ascospores that cling onto substrates of wood, algae, or sand. It is found in the mesohaline zone of many different coastal countries. It has been mistaken for a new fungal species Dryosphaera navigans and has yet to be assigned to a class, order, or family.
The Chaetomiaceae are a family of fungi in the Ascomycota, order Sordariales, class Sordariomycetes. Chaetomiaceae are usually saprobic or parasitic. Cheatomiaceae are a great source of enzymes with diverse biotechnological and industrial applications such as PMO, L-methioninase, β-1,3-glucanase, laccase, dextranase, lipolytic, pectinolytic, amylolytic, chitinolytic, and proteolytic enzymes. The production of such compounds can be taken into account as candidates for the development of effective and novel lead compounds for medicine, biological control and production of bioactive secondary metabolites. Chaetomiaceae furthermore contains some of the most well known thermophilic fungi, an interesting feature carrying many biological applications, but that is found only in few fungal genera.
Chaetomium cupreum is a fungus in the family Chaetomiaceae. It is able to decay in manufactured cellulosic materials, and is known to antagonize a wide range of soil microorganisms. This species is component of the biocontrol agent, Ketomium, a commercial biofungicide. It has also been investigated for use in the production of natural dyes. Chaetomium cupreum is mesophilic and known to occur in harsh environments and can rapidly colonize organic substrates in soil. Laboratory cultures of C. cupreum can be propagated on a range of common growth media including potato dextrose at ambient or higher than ambient temperature producing cottony white colonies with a reddish reverse.
Magnaporthiopsis is a genus of ascomycete fungi. It has three species.
Aspergillus unguis is a species of fungus in the genus Aspergillus, and the asexual state (anamorph) of Emericella unguis. Aspergillus unguis is a filamentous soil-borne fungus found on decomposing plant matter and other moist substrates including with building materials and household dust. Aspergillus unguis occurs mainly in tropical and subtropical soils but has also been isolated from various marine and aquatic habitats. The species was first isolated in 1935 by Weill and L. Gaudin. Historically, A. unguis was assigned to the A. nidulans group, a common group of soil-borne fungi due to the resemblance of its ascospores and cleistothecia to those of Emericella nidulans. Aspergillus unguis is distinctive, however, in possessing spicular hyphae. A number of synonyms have been collapsed into this species, including Sterigmatocystis unguis, Aspergillus laokiashanensis and Aspergillus mellinus.
Chaetomium atrobrunneum is a darkly pigmented mould affiliated with the fungal division, Ascomycota. This species is predominantly saprotrophic, although it has been known to infect animals including humans, showing a proclivity for the tissues of the central nervous system. Chaetomium atrobrunneum was described in 1949 from a mouldy military mattress cover obtained from the island of Guadalcanal.
Botryotrichum murorum is a common soil and indoor fungus resembling members of the genus Chaetomium. The fungus has no known asexual state, and unlike many related fungi, is intolerant of high heat exhibiting limited growth when incubated at temperatures over 35 °C. In rare cases, the fungus is an opportunistic pathogen of marine animals and humans causing cutaneous and subcutaneous infection.
Chaetomium elatum is a very common and widely distributed saprotrophic fungus of the Chaetomiaceae family of molds which has been found to grow on many different substances all over the world. It was first established by Gustav Kunze after he observed it growing on dead leaves. Its defining features that distinguish it from other Chaetomium species are its extremely coarse terminal hairs and the lemon-shaped morphology of its ascospores. It produces many metabolites with potential biotechnology uses including one with promise against the rice blast disease fungus, Magnaporthe grisea. It shows very little pathogenic ability causing confirmed disease in only a few plant species.
Collariella bostrychodes is a fungal decomposer of lignin and carbohydrate in the family Chaetomiaceae commonly found in soil and dung. The fungus is distinguished by a darkened collar-like ostiole around the ostiolar pore, giving the fungus its name. The fungus is highly variable in shape and form, giving raise to the belief that there are two subclades in the species. The ascospores range from lemon-shaped to nearly spherical with slightly pointed ends. It can grow to be pale green and later turn pale bluish grey or olivaceous with age. The fungus produces the toxic secondary metabolite, chaetochromin.
Chaetomium subspirale is a fungus from the phylum Ascomycota. It was described by A. H. Chivers in 1912 in America. The species has sexual fruiting bodies that are ornamented with characteristic, coiled hairs giving it a wooly appearance. C. subspirale colonies are brown, which the characteristic hairs are also responsible for. It is commonly found in various soil and dung samples. C. subspirale produces the mycotoxin, oxaspirodion, which inhibits inducible TNF-a expression and inhibits the activation of the transcription factor NF-kappaB.
Botryotrichum piluliferum is a fungal species first identified in 1885 by Saccardo and Marchal. It was discovered to be the asexual state of a member of the ascomycete genus, Chaetomium. The name B. piluliferum now applies to the fungus in all its states. B. piluliferum has been found worldwide in a wide range of habitats such as animal dung and vegetation. The colonies of this fungus start off white and grow rapidly to a brown colour. The conidia are smooth and white. B. piluliferum grows optimally at a temperature of 25-30 °C and a pH of 5.5.
Arcopilus aureus is a plant and soil fungus in the genus Arcopilus. It was first identified by A. H. Chivers in 1912, who named it Chaetomium aureum. It was later transferred to the genus Arcopilus by Wang and colleagues. The fungus has recently been recognized to have industrial use for the production of the metabolites resveratrol. and sclerotiorin Additionally, A. aureus has high lead tolerance and clearance, suggesting a potential role in environmental biotechnology.
Myxotrichum chartarum is a psychrophilic and cellulolytic fungus first discovered in Germany by Gustav Kunze in 1823. Its classification has changed many times over its history to better reflect the information available at the time. Currently, M. chartarum is known to be an ascomycete surrounded by a gymnothecium composed of ornate spines and releases asexual ascospores. The presence of cellulolytic processes are common in fungi within the family Myxotrichaceae. M. chartarum is one of many Myxotrichum species known to degrade paper and paper products. Evidence of M. chartarum "red spot" mold formation, especially on old books, can be found globally. As a result, this fungal species and other cellulolytic molds are endangering old works of art and books. Currently, there is no evidence that suggests that species within the family Myxotrichaceae are pathogenic.
Ascodesmis nigricans is a coprophilous fungus that could be isolated from the dung of various animals. It was firstly introduced by Philippe Édouard Léon Van Tieghem, a French botanist, and was the type species of the genus Ascodesmis. It is an uncommon species but its development of the fruit body has been the subject of much laboratory study due to the easy nature of its cultivation. Ascodesmis nigricans is not pathogenic to human, animals or plants. This species has world-wide distribution.
Savoryellaceae is a family of aquatic based fungi. It is the only family in the monotypic order Savoryellales within the class Sordariomycetes, division Ascomycota.
Savoryella is a genus of freshwater and marine based fungi in the family Savoryellaceae and the order Savoryellales.
