Type species: Nematostoma artemisiae Syd. & P. Syd., Annls mycol. 12(2): 161 (1914).

Notes: Boonmee et al. (2017) revisited Nematostoma and accepted this genus in Pseudoperisporiaceae based on parasitic and saprobic habit on leaves. Taxa in this genus are widely distributed such as in Argentina, Japan, Mexico, the USA and other tropical countries. Boonmee et al. (2017) provided a description and illustration of the holotype specimen Nematostoma artemisiae, habit on living leaves of Artemisia vulgaris var. indica from Japan.
