Mucor spores or sporangiospores can be simple or branched and form apical, globular sporangia that are supported and elevated by a  column-shaped columella. Mucor species can be differentiated from molds of the genera Absidia, Rhizomucor, and Rhizopus by the shape and insertion of the columella, and the lack of stolons and rhizoids.
Mucor spores or sporangiospores are either simple or branched and form spherical sporangia that are elevated by a column-shaped structure called a columella.  The genus Mucor can be distinguished from molds like Absidia, Rhizomucor, and Rhizopus by the shape of the columella and the absence of stolons and rhizoids.
