A violet root rot fungus recently found in Japan was identified as Helicobasidium brebissonii. The fungus was compared with another violet root rot fungus, H. mompa, which is distributed throughout Japan, in terms of morphological characteristics of the basidiospores and the conidial state, sequences of rDNA ITS regions, and pathogenicity on carrot, sweet potato and apple rootstock. The two species were clearly discriminated by these features and the taxonomic status of both species is discussed.
最近在日本发现的一种紫罗兰根腐病菌被鉴定为短柄胶锈菌。该真菌与另一种分布于日本各地的紫罗兰根腐病菌——桑寄生胶锈菌，在担孢子和分生孢子状态的形态特征、rDNA ITS区域序列以及对胡萝卜、甘薯和苹果砧木的致病性方面进行了比较。通过这些特征可以清楚地区分这两个物种，并对这两个物种的分类地位进行了讨论。
