摘要

胞孢子菌是一种重要的病原菌,分布在世界各地,寄主范围广,通常与树木枯死病和溃疡病有关。缺乏前型培养或无法将GenBank中的多基因DNA序列数据与系统发育分析联系起来,使得很难将胞孢子虫分类群划分到物种水平。本研究从中国、意大利和泰国的枯木中采集了10份胞孢子虫标本。根据其形态和系统发育特征,对4个新种(C. diopuiensis、C. galegicola、C. pingbianensis和C. pubescentis)和4个已知种(C. cedri、C. cotini、C. predappioensis和C. prunicola)进行了描述、说明,并与相关分类群进行了比较。详细描述了全形态(C. galegicola、C. prunicola、C. predpioensis和C. pubescentis)、性形态(C. cedri、C. cotini、C. diopuiensis和C. pingbianensis)和中国新记录的C. preddappioensis。ITS, LSU, ACT和RPB2 DNA序列数据集的系统发育分析支持它们在胞孢子属中的位置,并证明了新种和已知种的鉴定。

Additions to the genus Cytospora with sexual morph in Cytosporaceae
Cytospora species are important pathogens, which have a worldwide distribution, broad host range and are commonly associated with tree dieback and canker disease. Lack of ex-type cultures or inability to link multi-gene DNA sequence data in GenBank to phylogenetic analyses makes it difficult to classify Cytospora taxa to species level. In this study, ten specimens of Cytospora were collected from dead wood in China, Italy and Thailand. Based on their morphology and phylogenetic characterization, four new species (C. diopuiensis, C. galegicola, C. pingbianensis and C. pubescentis) and four known species (C. cedri, C. cotini, C. predappioensis and C. prunicola) are herein described, illustrated and compared with related taxa. Detailed morphological descriptions of the holomorph (C. galegicola, C. prunicola, C. predappioensis and C. pubescentis), the sexual morph (C. cedri, C. cotini, C. diopuiensis and C. pingbianensis) and a new record of C. predappioensis in China are provided. Phylogenetic analyses of a combined ITS, LSU, ACT and RPB2 DNA sequence dataset support their placement in the genus Cytospora and justify the new species and identification of known species.
