Species of Eucalyptus are widely planted as exotics in the tropics and Southern Hemisphere and to some extent in southern Europe, for timber and fibre production. Species of Mycosphaerella are commonly associated with leaves and twigs of Eucalyptus and can result in defoliation, dieback, and even tree death. In the present study, numerous isolates of Mycosphaerella species were collected from leaf litter, living leaves exhibiting leaf spot symptoms or severe Mycosphaerella leaf blotch symptoms. Isolates were compared based on DNA sequence data for the internal transcribed spacer region (ITS1 & ITS2) and the 5.8S gene. These data, together with characteristics of the fungal growth on three different media, morphology of the anamorph and teleomorph structures as well as ascospore germination patterns were used to describe 21 new species.
桉树物种作为热带和南半球的外来种被广泛种植，在一定程度上也被种植在欧洲南部，用于木材和纤维生产。球腔菌属物种通常与桉树的叶子和小枝有关，可能导致落叶、枯枝，甚至树木死亡。在本研究中，从落叶、表现叶斑症状或严重球腔菌叶斑症状的活叶中收集了大量球腔菌属种的分离物。根据内部转录间隔区（ITS1 和 ITS2）和 5.8S 基因的 DNA 序列数据对分离物进行了比较。这些数据，加上真菌在三种不同培养基上的生长特性、无性态和有性态结构的形态以及分生孢子萌发模式，用于描述了 21 个新种。
