Zygomycota. 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. [1] Approximately 1060 species are known. [2] They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material.
A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists.Zygospores are created by the nuclear fusion of haploid cells. In fungi, zygospores are formed in zygosporangia after the fusion of specialized budding structures, from mycelia of the same (in homothallic fungi) or different mating types (in heterothallic fungi), and may be chlamydospores.

In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. Anamorph: an asexual reproductive stage (morph), often mold -like. When a single fungus produces multiple ...
In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi.

Fungi are fundamental for life on earth in their roles as symbionts, e.g. in the form of mycorrhizae, insect symbionts, and lichens. Many fungi are able to break down complex organic biomolecules such as lignin , the more durable component of wood , and pollutants such as xenobiotics , petroleum , and polycyclic aromatic hydrocarbons .
Morphology. Mortierella fungi are typically coenocytic, but compared with the genus Mucor (Mucoromycotina, Mucorales), they have a stronger tendency towards septum formation. Compared with Mucor -like fungi, the mitosporangia are typically smaller, contain fewer spores and lack a columella (Fig. 1). Many Mortierella -like fungi are asexual.
Hyaloraphidiales. Sanchytriomycetes [1] Sanchytriales. Chytridiomycota are a division of zoosporic organisms in the kingdom Fungi, informally known as chytrids. The name is derived from the Ancient Greek χυτρίδιον (khutrídion), meaning "little pot", describing the structure containing unreleased zoospores.
Endogone species are sporocarpic—they form a fruit body termed a sporocarp, on which spore-bearing structures are borne. The zygospores—a diploid reproductive stage in the life cycle —are formed above the point of union of two gametangia, or from a budding from the larger of the two. [ 8 ] Species in the genus can be saprobic ...
