Sporocadaceae is a species-rich and cosmopolitan fungal family including species of plant pathogens, endophytes or saprobes, and parasites of humans and animals. The taxonomy of Sporocadaceae has recently been revised using a polyphasic approach. However, much remains unknown about the diversity of species and their host associations. A collection of 488 strains, mostly from China and associated with 129 host plant species, was studied based on morphological comparisons and multi-locus (LSU, ITS, tef-1α , tub2 , and rpb2 ) phylogenies. Our results revealed that they belonged to 86 species, one new genus ( Cavernicola gen. nov .) and seven known genera, including Discosia , Monochaetia , Neopestalotiopsis , Pestalotiopsis, Seimatosporium , Seiridium and Sporocadus . Of these, 43 new species and three new combinations ( Dis . kaki , Mon . bulbophylli , and Neo . keteleeriae ) are proposed in this paper. In addition, Neo. vaccinii , Pes. kaki and Pes. nanjingensis are synonymised under Neo. hispanica , Pes. menhaiensis and Pes. sichuanensis , respectively. We also corrected seven problematic sequences of type materials of previously published species, namely Neo . iranensis ( tef-1α , ITS, tub2 ), Pes . jesteri ( tef-1α ), Pes . photinicola (ITS, tub2 ) and Pes . yunnanensis (ITS). Based on this study, Pestalotiopsis and Neopestalotiopsis are the most commonly detected genera within the Sporocadaceae family, associated with 84 and 70 plant species, respectively. Furthermore, con...
