Type species: Nematostigma obducens Syd. & P. Syd., Annls mycol. 11(3): 262 (1913).

Notes: The genus is characterized by dark brown, sparse setae, sphaerical ascomata, and hyaline, multi-septate ascospores. Nematostigma was transferred to Dimeriaceae, Parodiopsidaceae (= Parodiellinaceae), and Pseudoperisporiaceae (Hansford 1946; von Arx and Müller 1975; Eriksson and Hawksworth 1993; Hawksworth et al. 1995; Barr 1997; Hyde et al. 2013). However, Boonmee et al. (2017) included this genus in Nematotheciaceae based on morphology.
