Quick Summary

The Mucoromycotina are a subphylum of fungi, commonly known as molds. These fungi are characterized by a mass of mycelium, which are vegetative filaments, and fruiting structures. Genera like Rhizopus, Aspergillus, and Penicillium belong to this group. Rhizopus species, such as the common bread mold Rhizopus stolonifer, are known for their rapid growth and the production of black spores.12

These fungi play roles in decomposition, food spoilage, and plant diseases. Some species of Rhizopus are industrially important, used in the production of lactic acid, cortisone, and in fermentation processes. However, certain Mucoromycotina can cause serious infections in humans, particularly in individuals with weakened immune systems, a condition known as mucormycosis.12
