A comparison of aspergillosis and mucormycosis highlights numerous similarities and interesting differences. GENERAL DESCRIPTION OF THE ORGANISM. Rhizopus reproduces asexually by sending up vertical stalk called sporangiophore which lumps at the tip to produce a sporangium. Mold species belonging to the genus Rhizopus cause the rot, which initially appears on the fruit as a fuzzy white mass, called the mycelium. Rhizopus is an organism which reproduces by spore formation. Rhizopus oryzae is a filamentous heterothallic microfungus that occurs as a saprotroph in soil, dung, and rotting vegetation.
