摘要多孔革菌属（Porodaedalea）是膜壳目（Hymenochaetales）的一个多孔菌属，是针叶树的病原菌。在这项研究中，我们进行了一个全面的研究的起源和多样性的Porodaedalea的基础上收集和分离自欧洲，北美，北非和亚洲。系统发育分析的两个基因的数据集，nuc核糖体DNA内部转录间隔区（ITS 1 -5. 8 S-ITS 2 = ITS）和翻译延伸因子1-α（tef 1），显示20个终端分支，对应于系统发育的物种内Porodaedalea支持。根据形态学证据，描述了5个新种：高山拟单胞菌P. alpicola、印度拟单胞菌P. indica、凯西拟单胞菌P. kesiyae、小种子拟单胞菌P. microsperma和云南拟单胞菌P. yunnanensis。此外，在北美和东亚发现了四个尚未命名的谱系。
ABSTRACT Porodaedalea is a polypore genus of the Hymenochaetales that encompasses pathogens of conifer trees. In this study, we conduct a comprehensive study of the phylogeny and diversity of Porodaedalea based on collections and isolates from Europe, North America, North Africa, and Asia. Phylogenetic analysis of a two-gene data set, nuc ribosomal DNA internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) and translation elongation factor 1-alpha (tef1), shows that 20 terminal clades that correspond to phylogenetic species well supported within Porodaedalea. Based on morphological evidence, five new species, P. alpicola, P. indica, P. kesiyae, P. microsperma, and P. yunnanensis, are described and illustrated. In addition, four still unnamed lineages are detected in North America and East Asia.
