In an ongoing survey of Korean indigenous fungi, two fungal strains (KNU16-74 and KNU16-99) belonging to the genus were isolated from field soil in Gyeongnam, Korea. Morphological characterization and phylogenetic analysis using sequence of the internal transcribed spacer regions were carried out to confirm its precise identification. These strains were identified as (KNU16-74) and (KNU16-99). To examine the keratin degradation efficiency of these two fungal species, human hair strands were incubated with fungus culture. Results revealed that these two fungal species have the ability to degrade keratin substrate. This is the first report of these two species in Korea.

在一项正在进行的韩国本土真菌调查中，从韩国庆南的田间土壤中分离出了属于该属的两种真菌菌株（KNU16 - 74和KNU16 - 99）。利用内部转录间隔区序列进行了形态学特征分析和系统发育分析，以确认其精确鉴定。这些菌株被鉴定为（KNU16 - 74）和（KNU16 - 99）。为了检测这两种真菌物种的角蛋白降解效率，将人发与真菌培养物一起孵育。结果表明，这两种真菌物种具有降解角蛋白底物的能力。这是这两个物种在韩国的首次报道。
