NotesAscochyta is a well-known pathogenic genus in Didymellaceae. Earlier this genus was described using its sexual morphs and Chen et al. (2015) linked asexual morph to this genus. They are characterised with oblong to ellipsoidal aseptate conidia in Didymellaceae. The host- specificity of the species belonging to this genus is rather restricted, and they occur mostly on the Campanulaceae, Chenopodiaceae, Leguminosae, Poaceae, Solanaceae and Umbelliferae (Valenzuela-Lopez et al. 2018). Some species are associated with one specific host, but may also be found on other related species of the same genus or family (Boerema & Bollen 1975). Even though there are 1438 records in Index Fungorum (2020) and 1347 records available in Mycobank (2020), currently only 18 species are accepted including two varieties of Ascochyta medicaginicola (Chen et al. 2017, Jayasiri et al. 2017b, Valenzuela-Lopez et al. 2018, Hyde et al.2018, Wanasinghe et al. 2018b).
