Genera

The Ancylistaceae are a family of fungi in the order Entomophthorales. [2] The family currently contains 3 genera: Ancylistes , Macrobiotophthora , Conidiobolus . [3] Capillidium was added in 2020, [4] it was once thought to be a sub-genus of Conidiobolus. [5] Microconidiobolus and Neoconidiobolus were also added in 2020. [6]

Brief taxonomic history

This family was originally an order thought to be included with the aquatic Phycomycetes and included members of Oomycota. [3] It was Helen Berdan, [7] who determined that Ancylistes belonged to order Entomophthorales. [8] Later, the Oomycetes were removed as were several zygomycete genera. [3]

Morphology

The mycelium is coenocytic or irregularly septate. The nuclei are small. During interphase, condense chromatin is absent, but a central nucleolus can be observed. The mycelium can become disjointed. [9] In Ancylistes, who are parasites of desmids (algae form), the hyphae grow toward the ends of the host. As the hyphae grow, branches that follow the groves between plates in the chloroplast are produced. Upon reaching the end, the hyphae grow toward the other end to completely encircle the chloroplast. Septa are produced progressively with segments containing many nuclei. [8] Conidia are produced singly on unbranched sporophores. [3] Like other members of Entomophthorales, conidia are forcibly discharged, which occurs through papillar eversion. [9] Zygospores are formed along the axis of conjugation [9] and can be angular in shape. [3]

Sexual Reproduction

Sexual reproduction results in the formation of a zygospore that functions as a resting spore. [9] The zygospore is formed by the fusion of gametangial cells or the scalariform fusion of hyphae. [3] Little is known about the zygospores. [9] [3]

Ecology

The genus Ancylistes are parasites of desmids, a group of green algae. [8] Macrobiotophthora are parasites of tardigrades and nematodes. [3] The genus Conidiobolus are common saprobes and occasional parasites of vertebrates or insects. [9] [3] Capillidium are also parasites of vertebrates or insects.

The most well known member is Conidiobolus coronatus , which is typically found in soils and parasitizing termites and aphids but has been known to infect mammals. [9]

<span class="mw-page-title-main">Ascomycota</span> Division or phylum of fungi

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 such as Cladonia belong to the Ascomycota.

<span class="mw-page-title-main">Zygomycota</span> Division or phylum of the kingdom Fungi

Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla: the Mucoromycota and Zoopagomycota. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycete hyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae. Zygomycota is no longer recognised as it was not believed to be truly monophyletic.

<span class="mw-page-title-main">Mucorales</span> Order of fungi

The Mucorales is the largest and best-studied order of zygomycete fungi. Members of this order are sometimes called pin molds. The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales.

<span class="mw-page-title-main">Entomophthorales</span> Order of fungi

The Entomophthorales are an order of fungi that were previously classified in the class Zygomycetes. A new subdivision, Entomophthoromycotina, in 2007, was circumscribed for them.

Sporogenesis is the production of spores in biology. The term is also used to refer to the process of reproduction via spores. Reproductive spores were found to be formed in eukaryotic organisms, such as plants, algae and fungi, during their normal reproductive life cycle. Dormant spores are formed, for example by certain fungi and algae, primarily in response to unfavorable growing conditions. Most eukaryotic spores are haploid and form through cell division, though some types are diploid sor dikaryons and form through cell fusion.we can also say this type of reproduction as single pollination

<i>Entomophthora</i> Genus of fungi

Entomophthora is a fungal genus in the family Entomophthoraceae. Species in this genus are parasitic on flies and other two-winged insects. The genus was circumscribed by German physician Johann Baptist Georg Wolfgang Fresenius (1808–1866) in 1856.

Phycomycetes is an obsolete polyphyletic taxon for certain fungi with aseptate hyphae. It is used in the Engler system. Asexual reproduction takes place by zoospores (motile) or by Aplanospores (non-motile). These spores are endogenously produced in sporangium. A zygospore is formed by fusion of two gametes. These gametes are similar in morphology (isogamous) or dissimilar.

Entomophthora muscae is a species of pathogenic fungus in the order Entomophthorales which causes a fatal disease in flies. It can cause epizootic outbreaks of disease in houseflies and has been investigated as a potential biological control agent.

Mucoromycotina is a subphylum of uncertain placement in Fungi. It was considered part of the phylum Zygomycota, but recent phylogenetic studies have shown that it was polyphyletic and thus split into several groups, it is now thought to be a paraphyletic grouping. Mucoromycotina is currently composed of 3 orders, 61 genera, and 325 species. Some common characteristics seen throughout the species include: development of coenocytic mycelium, saprotrophic lifestyles, and filamentous.

Entomophthoromycota is a division of kingdom fungi. In 2007, it was placed at the taxonomic rank of subphylum in the most recent revision of the entire fungus kingdom.

Divided into three classes and six families, it contains over 250 species that are mostly arthropod pathogens or soil- and litter-borne saprobes.

<i>Zoophagus</i> Genus of fungi

Zoophagus is a genus of zygomycete fungi that preys on rotifers and nematodes. It was established in 1911 by Sommerstorff, who originally considered it to be an oomycete. It is common in a variety of freshwater habitats, such as ponds and sewage treatment plants.

Zoophthora is a genus of fungi in the family Entomophthoraceae. Like other taxa in this family, Zoophthora species cause disease in insects and as such are considered entomopathogenic fungi.

Stylopage is a polytypic genus of predacious fungus in the order Zoopagales, within the subphylum Zoopagomycotina. All known species of Stylopage subsist on various species of amoebae or nematodes by trapping their prey, typically using an adhesive substance that coats their vegetative hyphae, and absorbing nutrients through the projection of a haustorium. 17 extant Stylopage species have been described thus far.
