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 variety of male copulatory organs in species of Dactylogyrus. Other characteristics of Dactylogyrus species include the appearance of four eye-spots, 14 marginal hooks (7 pairs), one to two connective bars and two needle-like structures and spindle-shaped dactylogyrid-type seminal vesicles. [5]
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.

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).
Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found in a wide variety of organic substances, including "mature fruits and vegetables", [2] jellies, syrups, leather, bread, peanuts, and tobacco.
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.
The genus Halimeda J.V. Lamouroux belongs to the order Bryopsidales under the family Halimedaceae. It has five monophyletic sections - Halimeda J.V. Lamouroux, Micronesicae Hillis-Col, Opuntia J. Agardh ex De Toni, Pseudo-opuntia J. Agardh ex De Toni, and Rhipsalis J. Agardh ex De Toni [13] - which were based on the differences in the fusions of medullary siphons. [10]
