Germ. 2: 240 (1870) Type species. Diaporthe eres Nitschke, Pyrenomyc. Germ. 2: 245 (1870). Notes. The genus Diaporthe (syn. Phomopsis ) was established by Nitschke (1870) . The identification of Diaporthe was confused due to the historical species recognition criteria based on overlapped morphology, culture characteristics and host affiliation ( Dissanayake et al. 2017 ). The phylogenetic analysis recommended to delimitate taxa to the species level was first proposed by Udayanga et al. (2012) and later modified to include concatenated alignments of ITS, cal1 , his3 , tef1-α , tub2 ( Gomes et al. 2013 ). More than 1,050 epithets for Diaporthe and 950 for Phomopsis are listed in Index Fungorum (August 2019). Dissanayake et al. (2017) provided most type/ex-type species details and phylogenetic frame with 172 species in this genus. Yang et al. (2018) summarized 15 species of Diaporthe associated with dieback disease of tree hosts in China and introduced 12 new species.
