This is the division of the fungus kingdom which contains bread molds. DivisionZygomycota bread mold These fungi are characterised by their asexual state, a zoospore (motile) with a single whiplash flagellum oriented and located posteriorly. The zoospore is formed in a sporangium. Zoospores are released through an opening in the wall, and their release usually indicates the death of the thallus. Zoospores of opposite mating type may meet, fuse (plasmogamy immediately followed by karyogamy) and go on to form a single resting sporangium. After meiosis, the sporangium germinates to release further zoospores, which may be asexual, in which case, the single zoospore attaches (encysts) to and colonises a substrate. The cyst may be a resting structure or it may grow to form a sporangium. It may be located on or in the substrate. In some species, resting sporangia may take the form of a multicelled, thick walled sorus. The sorus is commonly found within parasitised tissue such as a root, where it remains until the surrounding tissue has rotted away.
