Two mutant isolates of Pyricularia oryzae formed abnormal, longer, cylindrical spores with more septa than those of normal, obpyriform spores of wild isolates. These isolates also produced normal spores, although their number was less than that of the abnormal spores. When normal and abnormal spores were single‐spore‐isolated from the lesions caused by the mutant isolates and inoculated to an agar medium, each colony produced both types of spores, regardless of the type of single spores used for inoculation.
