与茶树和其他茶树的症状和无症状组织相关的似拟青霉分离物共124株。对来自8个省份的中国进行了调查。根据单基因座和多基因座(ITS、TEF、TUB2)的系统发育，以及形态特征、寄主组合和地理分布，它们至少被划分为3属19种，即新拟青霉属、拟青霉属和拟青霉属。记述了拟青霉属8个新种和拟青霉属3个新种。我们的数据表明，目前在拟青霉属中广泛使用的基因座不能一致地提供稳定和足够的分辨率树状拓扑结构，特别是对于新拟青霉属。此外，分生孢子基附属物的数量、分枝方式和长度也是拟盘孢属的系统发育特征。
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.
