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.
A common example of a zygomycete is black bread mold (Rhizopus stolonifer), a member of the Mucorales. It spreads over the surface of bread and other food sources, sending hyphae inward to absorb nutrients. In its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, each containing hundreds of haploid spores.

A hypha (from Ancient Greek ὑφή (huphḗ) 'web'; pl.: hyphae) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. [1]
Mucoralean fungi are typically fast-growing, and their wide hyphae (long, filamentous structures) lack septa (multi-perforate septa are present only in sporangiophores and gametangia). The hyphae grow mostly within the substrate. Sporangiophores are upright (simple or ramified) hyphae, that support sac-like sporangia filled with asexual ...
This fossil, classified in the form genus Palaeancistrus, has hyphae that compare with extant saprophytic basidiomycetes. [5] The oldest known clamp connections exist in fossilized hyphae growing in the fossil fern Botryopteris antiqua, which predate Palaeancistrus by about 25 Ma. [6]
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. [3]
Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing ...
Zygospores are formed in certain fungi (zygomycota, for example Rhizopus) and some algae (for example Chlamydomonas). The zygospore forms through the isogamic fusion of two cells (motile single cells in Chlamydomonas) or sexual conjugation between two hyphae (in zygomycota). Plasmogamy is followed by karyogamy, therefore zygospores are diploid
