UNLABELLED
Phyllosticta is a geographically widespread genus of plant pathogenic fungi with a diverse host range. This study redefines Phyllosticta, and shows that it clusters sister to the Botryosphaeriaceae (Botryosphaeriales, Dothideomycetes), for which the older family name Phyllostictaceae is resurrected. In moving to a unit nomenclature for fungi, the generic name Phyllosticta was chosen over Guignardia in previous studies, an approach that we support here. We use a multigene DNA dataset of the ITS, LSU, ACT, TEF and GPDH gene regions to investigate 129 isolates of Phyllosticta, representing about 170 species names, many of which are shown to be synonyms of the ubiquitous endophyte P. capitalensis. Based on the data generated here, 12 new species are introduced, while epitype and neotype specimens are designated for a further seven species. One species of interest is P. citrimaxima associated with tan spot of Citrus maxima fruit in Thailand, which adds a fifth species to the citrus black spot complex. Previous morphological studies lumped many taxa under single names that represent complexes. In spite of this Phyllosticta is a species-rich genus, and many of these taxa need to be recollected in order to resolve their phylogeny and taxonomy.

未加标签
Phyllosticta 是一个地理分布广泛的植物病原真菌属，具有多样化的宿主范围。本研究重新定义了 Phyllosticta，并表明它与 Botryosphaeriaceae（Botryosphaeriales，Dothideomycetes）聚类姐妹群，其中较旧的科名 Phyllostictaceae 被复活。在真菌采用单元命名法时，我们选择了 Phyllosticta 这个通用名称而不是 Guignardia，这是我们在这里支持的方法。我们使用 ITS、LSU、ACT、TEF 和 GPDH 基因区域的多基因 DNA 数据集来研究 129 株 Phyllosticta，代表约 170 个种名，其中许多被证明是无处不在的内生菌 P. capitalensis 的同义词。根据这里生成的数据，引入了 12 个新种，同时为另外 7 个种指定了副模式和新模式标本。一个有趣的种是 P. citrimaxima，它与泰国蜜桔果实上的 tan spot 有关，这为柑橘黑斑病复合体增加了第五个种。先前的形态学研究将许多分类群归为单一名称，代表复合物。尽管如此，Phyllosticta 仍然是一个物种丰富的属，其中许多分类群需要重新采集，以解决其系统发育和分类学问题。
