It has been studied whether any nuclear difference exists between the variants reported before and their parent strain. We selected two albino-type strains and one green-type strain from the variants and examined their nuclei after staining by FEULGEN's method or DELAMATER's method. It has been recognized that albino-type strains contain more numerous nuclei in vesicle, sterigma, conidium and mycelium than the parent strain, while the greentype strain and the parent strain are scarcely different in the number of nuc1ei in these parts. Teratologic forms of vesicle and sterigma appeared much more frequently on treating with electric supersonic wave and the number of nuclei in them was larger than that in the normal form. Moreover, the nuclei of the teratologic forms were elongated. The nuclei in normal cells of the variants are more elongated at anaphase than those of the parent strain.
