Kingdom: Fungi
Phylum: Zygomycota
Class: Zygomycetes
Order: Mucorales
Family: Mucoraceae
Genus: Mucor
Species: M. racemosus

*Non-motile asexual sporangiospores in columellate sporangia

*Sexual reproduction by direct fusion of multinucleate gametangia to form a multinucleate zygospore.

*Spores are dispersed by wind, by water, or by animals

*Most are saprophytic (grow on dead or decayed organic matter), many are coprophilous (on dung)

*My sample is obtained from squirrel dung on the campus
