Diluviicola was introduced for a freshwater species D. capensis collected from Brunei (Hyde et al. 1998). Diluviicola is unique in having bipolar conical caps attached to ascospore tips and detached once released in water, with a flexible filament which unfurls from within the caps (Hyde et al. 1998). Zhang et al. (2017) introduced a new species D. aquatica based on its similar ascomata lying horizontally on the host substrate and unfurling mechanisms of ascospore appendages with D. capensis. We provide sequence data for D. capensis with a description and illustration, and transfer D. aquatica to a new genus Neodiluviicola based on morphology and phylogeny (see notes under Neodiluviicola).
