Because leaf spot suspected of the participation of genus of Phyllsticta was observed in Acer pycnanthum that was a Japanese endemic species, investigations were performed with five prefectures of nine places including Nagano of natural habitat. As a result of investigation, serious damage was observed in all investigations place. The fungus observed on the emerging disease of A. pycnanthum was identified as Phyllosticta minima. It was newly recorded in Japan. Leaf spot symptoms appeared within about 1 month after inoculation by sprayed conidial suspensions of P. minima. A same fungus was re-isolated from lesions of the diseased tree. This is the first record of this fungal species causing a plant disease in Japan. Furthermore, the specific primer set that detected only fungus of P. minima was made, and there were some problems, but a quick and precise diagnosis was enabled.

由于在日本特有种的尖叶槭中观察到疑似参与Phyllsticta属的叶斑病，因此在自然栖息地长野等9个地方的5个县进行了调查。调查结果表明，在所有调查地点都发现了严重的损坏。在A. pycnanthum鉴定为Phyllosticta minima。这是日本的新记录。接种后1个月左右出现叶斑症状。从病树的病斑中重新分离到相同的真菌。这是日本首次发现这种真菌引起植物病害。此外，制备了仅检测微小青霉真菌的特异性引物组，存在一些问题，但能够进行快速准确的诊断。
