Chinese yam () has been cultivated as a food crop in Japan. The blue mold disease of Chinese yam during the storage and treatment of forced sprouting is one of the hindrances in attaining productivity that can lead to food security in tropical countries and steady farming that will eventually lead to farmers' profitability. In this study, three species of the genus related to the blue mold of yam were isolated from two locations in Hokkaido, Japan. From the morphology and phylogeny, these were , , and . Pathogenicity was confirmed in all -like isolates, and sensitivity against benomyl was evaluated based on MIC. The first two species were newly recorded as the causal fungi of the blue mold of yam in Japan, and the pathogenicity of is first confirmed in yam seed tuber. Moreover, some isolates showed possible resistance to benomyl.
山药（）在日本作为粮食作物进行种植。山药在贮藏和催芽处理过程中的青霉病是实现热带国家粮食安全和稳定农业生产（最终实现农民盈利）生产力的障碍之一。在本研究中，从日本北海道的两个地点分离出了与山药青霉相关的三种 属物种。根据形态学和系统发育学，这些物种分别为 、 和 。在所有类似 的分离株中均证实了致病性，并基于最低抑菌浓度（MIC）评估了对苯菌灵的敏感性。前两个物种被新记录为日本山药青霉病的致病真菌，并且 在山药种薯中的致病性首次得到证实。此外，一些分离株显示出对苯菌灵可能的抗性。
