Conidia of Aspergillvs sojae SAKAGUCHI et YAMADA were exposed to ultraviolet radiation and random isolation was made from colonies resulting from irradiated spores. From approximately four hundred of these mutants heavy, light and bluish green types were obtained besides 11 types the author reported in Part II.(1) Mutants of heavy and light types differred markedly from the parent strain in the shades of conidial heads and mutants of bluish green type apparently differred from the parent culture only in bluish green colored conidial heads. Morphological changes were observed in especially light type mutants. All mutants of these types remained stable genetically when recultivated through ten successive culture generations and single spore isolation through three successive culture upon Czapeks agar.
