Mitochondrial DNA (mtDNA) analysis with restriction enzymes, Hae III, Hind III and Msp I was performed in 17 Exophiala moniliae strains. The results were as follows: (1) E. moniliae could be classified into 10 types based on restriction patterns, (2) E. moniliae is suggested to be a complex organism because of extensive mtDNA polymorphism among strains like E. jeanselmei and (3) two types of E. moniliae are identical with two types of E. jeanselmei. These results suggest that E. moniliae is not genetically defined from E. jeanselmei and the taxonomical status of E. moniliae requires reevaluation.
运用限制性内切酶Hae III、Hind III和Msp I对17株分支状外瓶霉进行了线粒体DNA（mtDNA）分析。结果如下：（1）基于限制性酶切图谱，分支状外瓶霉可分为10种类型；（2）由于分支状外瓶霉菌株间存在广泛的mtDNA多态性，提示其为一种复合生物，类似杰氏外瓶霉；（3）分支状外瓶霉的两种类型与杰氏外瓶霉的两种类型相同。这些结果表明，分支状外瓶霉与杰氏外瓶霉在基因上并无明确界定，分支状外瓶霉的分类地位需要重新评估。
