Phylogeny and global diversity of Porodaedalea, a genus of gymnosperm pathogens in the Hymenochaetales

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.

Summary: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.
