A fungal pathogen was isolated from<I>Zoysia</I>grass leaf blight, so called'inu-no-ashiato', commonly infested in golf courses in Japan. From diagnostic studies, this fungus was considered nonspore forming type associated with genus <I>Curvularia</I>, grown with colored, septated thick wall mycelium looks as chlamydospores on PSA m edium. All of the culture experiments for inducing sporulatoin of the fungus has not succeeded. Ther efore, an identificatoin of this fungus was not achieved yet.<BR>Isolations of the fungus were obtained frequently from diseased materials in<I>Zoysia</I>grass, but did rare from the healthy part. In inoculatoin tests of the isolates to<I>Zoysia</I>grass of pot grown sod or field turf, a typical leaf blight has appeared with similar symptoms of the disease'inu-no-ashiato'in naturally infested<I>Zoysia</I>grass. Two different species of<I>Curvularia</I>, which are comfirmed<I>C. geniculata</I>and<I>C. lunata</I>respectively, were found also in high frequency from both diseased and healthy<I>Zoysia</I>grass, but their pathogenicity was not confirmed clearly.
