Type species: Diaporthe eres Nitschke
Notes: Diaporthe is the type genus of Diaporthaceae, and it was established by Nitschke (1867) to accommodate taxa with stromata in the Sphaeriales which are often with blackened zones in the substrate, ellipsoid to fusiform ascospores and enclosed, unilocular pycnidia that contain spermatia, stylospores and conidia (Wehmeyer 1933). Diaporthe species are saprobes, pathogens and endophytes and have a worldwide distribution (Dissanayake et al. 2017). Phomopsis was earlier the asexual morph (Udayanga et al. 2012). However, these genera were linked based on principle of significance and Diaporthe was nominated over Phomopsis to resolve nomenclatural complications (Rossman et al. 2015). The genus contains 1067 epithets listed in Index Fungorum 563 (August 2019), but fewer than 200 species are accepted (Dissanayake et al. 2017).
