During an investigation of microorganisms and pests in plant culture media from imported anthurium pots, a fungal isolate (DUCC4002) was detected. Based on its morphological characters including colony shape on potato dextrose agar, the microstructures of spores observed by light and scanning electron microscopy and the results of phylogenetic analysis using an internal transcribed spacer rDNA sequence, the fungal isolate was identified as Myrothecium roridum. Pathogenicity testing on anthurium leaves revealed that the fungus could colonize and produce sporodochia on the inoculated leaves. This is the first report of M. roridum detected in imported plant culture medium in Korea.

在对进口红掌盆栽植物栽培介质中的微生物和害虫进行调查期间，检测到一种真菌分离株（DUCC4002）。根据其形态特征，包括在马铃薯葡萄糖琼脂上的菌落形态、通过光学显微镜和扫描电子显微镜观察到的孢子微观结构以及使用内部转录间隔区rDNA序列进行的系统发育分析结果，该真菌分离株被鉴定为轮枝霉。对红掌叶片进行的致病性测试表明，该真菌可在接种叶片上定殖并产生分生孢子盘。这是韩国在进口植物栽培介质中检测到轮枝霉的首次报道。
