Diplodia Fr., in Montagne, Annls Sci. Nat., Bot., sér. 2 1: 302 (1834), Index Fungorum number: IF 8047

Diplodia is a well-known genus and is typified by Diplodia mutila (Fr.: Fr.) Fr. Diplodia species are pathogens or saprobes, mainly on woody hosts with a worldwide distribution (Phillips et al. 2013; Hyde et al. 2014; Ariyawansa et al.2015b). There are 1251 species epithets for Diplodia in Index Fungorum (2016) and recollection, epitypification and molecular analysis are required to confirm the placement of those species, as currently only 17 Diplodia species are known from a molecular basis (Phillips et al. 2013).
