Species of Mycosphaerella and Teratosphaeria represent important foliicolous pathogens of Proteaceae. Presently approximately 40 members of these genera (incl. anamorphs) have been recorded from Proteaceae, though the majority are not known from culture, and have never been subjected to DNA sequence analysis. During the course of this study, epitypes were designated for several important species, namely Batcheloromyces leucadendri, B. proteae, Catenulostroma macowanii, Mycosphaerella marksii, Teratosphaeria bellula, T. jonkershoekensis, T. parva, and T. proteae-arboreae. Several species were also newly described, namely Batcheloromyces sedgefieldii, Catenulostroma wingfieldii, Dissoconium proteae, Teratosphaeria persoonii, T. knoxdavesii, and T. marasasii. Although accepted as being highly host specific, some species were shown to have wider host ranges, such as M. communis (Eucalyptus, Protea), M. konae (Leucospermum, Eucalyptus), M. marksii (Eucalyptus, Leucadendron), T. associata (Eucalyptus,Protea), and T. parva (Eucalyptus, Protea), which in most cases were found to co-occur with other species of Mycosphaerella or Teratosphaeria on Proteaceae. Furthermore, earlier records of T. jonkershoekensis on Proteaceae in Australia were shown to be representative of two recently described species, T. associata and T. maxii. A phenomenon of underdeveloped, or micro-ascospores was also newly observed in asci of T. maculiformis and T. proteae-arboreae. The exact purpose of asci with two distinct types of ascospores remains to be clarified, as both types were observed to germinate on agar.
球腔菌属和突脐孢属的种代表重要的叶生病原菌。目前，从Proteaceae 中记录了大约 40 个属（包括无性型）的成员，尽管大多数种未经培养，也从未进行过 DNA 序列分析。在本研究过程中，为几个重要种指定了正模，即：叶斑球腔菌、保护球腔菌、Macowan 旋腔孢、Marks 球腔菌、拟贝雷芽枝霉、Jonkershoek 突脐孢、小突脐孢和树生突脐孢。还新描述了几个种，即：Sedgefield 球腔菌、Wingfield 旋腔孢、保护拟盘多毛孢、Person 突脐孢、Knoxdavies 突脐孢和 Marasas 突脐孢。尽管被认为具有高度宿主特异性，但有些种的宿主范围较广，例如：普通球腔菌（桉树、山龙眼）、Konae 球腔菌（帝王花、桉树）、Marks 球腔菌（桉树、白千层）、拟关联突脐孢（桉树、山龙眼）和小突脐孢（桉树、山龙眼），在大多数情况下，这些种与山龙眼科植物上的其他球腔菌或突脐孢种共存。此外，在澳大利亚山龙眼科植物上的 Jonkershoek 突脐孢的早期记录被证明代表了两个最近描述的种，即关联突脐孢和 Maxii 突脐孢。微孢子现象也在 Maculiformis 突脐孢和树生突脐孢的子囊中被新观察到。具有两种不同类型的子囊孢子的子囊的确切目的仍有待澄清，因为两种类型的孢子都在琼脂上观察到萌发。
