Engyodontium
Engyodontium is a genus of fungi belonging to the group Hyphomycetes and contains about 6 species. This fungus was formerly included in ''Beauveria'', but is now recognized as a distinct genus. Outdoors it is common in soil and plant debris. Indoors, it can be found on paper, textiles, jute, and painted walls. The most common species is ''E. album''. It forms a cottony, white colony producing numerous dry, tiny conidia. Production of mycotoxins by this fungus has not been reported at this time. It is an opportunist fungus and causes brain abscesses, keratitis, and native valve endocarditis Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves. Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the ... to immunocompromised people.

Cordycipitaceae
The Cordycipitaceae are a family of parasitic fungi in the Ascomycota, class Sordariomycetes and order Hypocreales. The family was first published in 1969 by mycologist Hanns Kreisel, but the naming was invalid according to the code of International Code of Nomenclature for algae, fungi, and plants. It was validly published in 2007. Description Cordycipitaceae species have stromata or subicula that are pallid or brightly pigmented and fleshy. Their perithecia are superficial to completely immersed in the substrate, and oriented at right angles to the surface of the stroma. The asci are cylindrical with a thickened ascus tip. Ascospores are usually cylindrical, contain multiple septa, and disarticulate into part-spores or remain intact at maturity.

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 ...

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 structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, 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 (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Sordariomycetes
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota), consisting of 28 orders, 90 families, 1344 genera. Sordariomycetes is from the Latin sordes (filth) because some species grow in animal feces, though growth habits vary widely across the class. Sordariomycetes generally produce their asci in perithecial fruiting bodies. Sordariomycetes are also known as Pyrenomycetes, from the Greek πυρἠν - 'the stone of a fruit' - because of the usually somewhat tough texture of their tissue. Sordariomycetes possess great variability in morphology, growth form, and habitat. Most have perithecial (flask-shaped) fruiting bodies, but ascomata can be less frequently cleistothecial (like in the genera '' Anixiella'', ''Apodus'', '' Boothiella'', ''Thielavia'', '' Zopfiella''),. Fruiting bodies may be solitary or gregarious, superficial, or immersed within stromata or tissues of the substrates and can be light to bright or black. Members of this group can grow ...

Hypocreales
The Hypocreales are an order of fungi within the class Sordariomycetes. In 2008, it was estimated that it contained some 237 genera, and 2647 species in seven families. Since then, a considerable number of further taxa have been identified, including an additional family, the Stachybotryaceae. According to the Catalog of Life, the Hypocreales contains 6 families, 137 genera, and 1411 species. Species of Hypocreales are usually recognized by their brightly colored, perithecial ascomata, or spore-producing structures. These are often yellow, orange or red. Genera ''incertae sedis'' According to a 2020 review of fungal classification, the following genera within the Hypocreales have an uncertain taxonomic placement (''incertae sedis''), and have not been assigned to any family: *'' Acremoniopsis'' – 1 sp. *'' Berkelella'' – 2 spp. *'' Bulbithecium'' – 1 sp. *'' Cephalosporiopsis'' – 10 spp. *'' Chondronectria'' – 1 sp. *'' Cylindronectria'' – 1 sp. *'' Diploos ...

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 ...

Hyphomycetes
Hyphomycetes are a form classification of fungi, part of what has often been referred to as fungi imperfecti, Deuteromycota, or anamorphic fungi. Hyphomycetes lack closed fruit bodies, and are often referred to as moulds (or molds). Most hyphomycetes are now assigned to the Ascomycota, on the basis of genetic connections made by life-cycle studies or by phylogenetic analysis of DNA sequences; many remain unassigned phylogenetically. Although no longer considered a phylogenetically defined taxon, the prevalence of hyphomycete forms in nature, the built environment, and laboratories means that identification of members this group remains of practical importance. Taxonomic and nomenclatural history Because asexual forms of fungi usually occur separately from their sexual forms, when microscopic fungi began to be studied in the early 19th century, it was often unknown when two morphologically different forms were actually part of one species. The tendency for some organisms to app ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Beauveria
''Beauveria'' is a genus of asexually-reproducing fungi allied with the ascomycete family Cordycipitaceae. Its several species are typically insect pathogens. The sexual states (teleomorphs) of ''Beauveria'' species, where known, are species of ''Cordyceps''. ''Beauveria'' species are white entomopathogenic fungi. They form unicellular conidia that are typically hydrophobic and very small. The conidia are formed holoblastically from basally inflated conidiogenous cells. After conidium production, the conidiogenous cell elongates before producing another conidium atop a small denticle (a narrow projection bearing a conidium or sporangium). The result is the formation of a distinctive, slender, zig-zag rachis. Colonies of ''Beauveria'' species are typically white or off-white on artificial culture media. Species of '' Tritirachium'' resemble ''Beauveria'' species in having a zig-zag conidiogenous cells, but differ in lacking conspicuous denticles and in producing yellow-brown ...

Jute
Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. "Jute" is the name of the plant or fiber used to make burlap, hessian, or gunny cloth. Jute is one of the most affordable natural fibers and second only to cotton in the amount produced and variety of uses. Jute fibers are composed primarily of plant materials cellulose and lignin. Jute fiber falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax ( linen), ramie, etc. The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and 1–4 meters (3–13 feet) long. Jute is also called the "golden fiber" for its color an ...

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of conidium ...
