A total of 124 Pestalotiopsis-like isolates associated with symptomatic and asymptomatic tissues of Camellia sinensis and other Camellia spp. from eight provinces in China were investigated. Based on single- and multi-locus (ITS, TEF, TUB2) phylogenies, as well as morphological characters, host associations and geographical distributions, they were classified into at least 19 species in three genera, i.e. Neopestalotiopsis, Pestalotiopsis and Pseudopestalotiopsis. Eight novel species in Pestalotiopsis and three novel species in Pseudopestalotiopsis were described. Our data suggested that the currently widely used loci in Pestalotiopsis-like genera do not consistently provide stable and sufficient resolution tree topologies, especially for Neopestalotiopsis. Moreover, the number, branch pattern and length of the conidial basal appendages were revealed to be phylogenetically informative characters in Pestalotiopsis.
共调查了来自中国 8 个省的与茶树及其他茶树属植物有症状和无症状组织相关的 124 个拟盘多毛孢属真菌分离物。基于单基因和多基因（ITS、TEF、TUB2）系统发育，以及形态特征、宿主相关性和地理分布，这些分离物被分为至少 3 个属的 19 个种，即 Neopestalotiopsis、Pestalotiopsis 和 Pseudopestalotiopsis。文中描述了 Pestalotiopsis 中的 8 个新种和 Pseudopestalotiopsis 中的 3 个新种。研究数据表明，目前在拟盘多毛孢属中广泛使用的基因座并不能一致地提供稳定且充分的分辨率树拓扑结构，特别是对于 Neopestalotiopsis。此外，发现分生孢子基部附属物的数量、分支模式和长度在拟盘多毛孢属中是具有系统发育信息的特征。
