Annotated notes on Diaporthe species

Diaporthe is a large and taxonomically complex genus, with over a thousand epithets listed in Index Fungorum. The placement of many Diaporthe species remains confusing, and there is a lack of consensus on their taxonomy and phylogeny. In this study, we provide annotated notes on accepted or presumed species of Diaporthe up to 2023. Our notes cover 832 species and include information on their morphology, ecology, geographic distribution, molecular data, and pathogenicity, where available. Diaporthe cyatheae comb. nov., D. pseudobauhiniae nom. nov., D. xishuangbannaensis nom. nov., D. krabiensis sp. nov., and D. pseudobiguttulata nom. nov. are introduced in this paper. In addition, we list 331 species that were previously classified as Diaporthe but are no longer accepted as members of the genus. Our comprehensive review of Diaporthe species provides a resource for researchers and taxonomists, enabling accurate identification and classification, and enhancing our understanding ecological roles of these fungi.
