The name Zygomycota refers to the zygosporangia characteristically formed by the members of this clade, in which resistant spherical spores are formed during sexual reproduction. Zygos is Greek for "joining" or "a yoke", referring to the fusion of two hyphal strands which produces these spores, and -mycota is a suffix referring to a division of ...
The study of reproduction and development in organisms was carried out by many botanists and zoologists.. Wilhelm Hofmeister demonstrated that alternation of generations is a feature that unites plants, and published this result in 1851 (see plant sexuality).
The zygosporangium is a unique structure to the Zygomycota and is easily recognizable in microscopy due to its characteristic dark color and spiky shape. The nuclei join in a process called karyogamy to form a zygote, which grows into a mature diploid zygomycete. A diploid zygomycete can then undergo meiosis to create spores, which disperse and ...

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.

Fungal fossils do not become common and uncontroversial until the early Devonian (416–359.2 Ma), when they are abundant in the Rhynie chert, mostly as Zygomycota and Chytridiomycota. [ 2 ] [ 23 ] [ 24 ] At about this same time, approximately 400 Ma, the Ascomycota and Basidiomycota diverged, [ 25 ] and all modern classes of fungi were present ...
The Zoopagomycotina are a subdivision (incertae sedis) of the fungal division Zygomycota sensu lato. [1] It contains 5 families and 20 genera. [2] Relationships among and within subphyla of Zygomycota are poorly understood, and their monophyly remains in question, so they are sometimes referred to by the informal name zygomycetes.
Endogonales is an order of fungi within the phylum of Zygomycota, [2] and in class Endogonomycetes. [ 3 ] [ 4 ] It contains 2 families ; Endogonaceae , with 6 genera and 38 species and Densosporaceae , with one genera and 4 species.
