2.4.1 Diaporthe

Dayarathne et al. (2020a) described three marine Diaporthe species: D. krabiensis, D. marina, D. salinicola, from mangrove wood. The scientific name Diaporthe salinicola is preoccupied by an earlier fungus (Spegazzini 1912), and so the new ‘ Diaporthe salinicola ’ was invalidly described (Nom. illegit., Art. 53.1). Diaporthe krabiensis, a species isolated from submerged wood of Bruguiera sp., was published without nomenclatural repository identifier (Nom. inval., Art. F.5.1 [Shenzhen]). In the present work, we validly publish Diaporthe salinicola and Diaporthe krabiensis .
