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.

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.
An immature zygosporangium of the Rhizopus fungus forming from two fused gametangia, showing a "yoke" shape.. 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.
It includes a diverse group of various molds, including the common bread molds Mucor and Rhizopus. [2] It is a sister phylum to Dikarya. [3] [4] Informally known as zygomycetes I, Mucoromycota includes Mucoromycotina, Mortierellomycotina, and Glomeromycotina, and consists of mainly mycorrhizal fungi, root endophytes, and plant decomposers.

A sporangium (from Late Latin, from Ancient Greek σπορά (sporá) 'seed' and ἀγγεῖον (angeîon) 'vessel'); pl.: sporangia) [1] is an enclosure in which spores are formed. [2]
A Gymnopilus clamp connection. A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi.It is a characteristic feature of basidiomycete fungi.
Phycomycetes is an obsolete [1] [2] [3] polyphyletic taxon for certain fungi with aseptate hyphae. [4] It is used in the Engler system. [5] Asexual reproduction takes place by zoospores (motile) or by Aplanospores (non-motile).
Spores can be classified in several ways such as by their spore producing structure, function, origin during life cycle, and mobility. Below is a table listing the mode of classification, name, identifying characteristic, examples, and images of different spore species.
