Neopyrenochaeta proposed by Valenz-Lopez et al. (2017) was based on molecular phylogeny. This genus was morphologically similar to Pyrenochaeta, but phylogenetically distinct. Neopyrenochaeta acicola is the type species of this genus. Neopyrenochaeta species were mainly reported as asexual morphs, however, Mapook et al. (2020) reported sexual morphs and pointed out that this genus has a wide host range. There are 15 accepted species in this genus (Valenz-Lopez et al. 2017, Jayasiri et al. 2019, Mapook et al. 2020, Magaña-Dueñas et al. 2021). 

Type species: Neopyrenochaeta acicola (Moug. & Lév.) Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, in Valenzuela-Lopez, Cano-Lira, Guarro, Sutton, Wiederhold, Crous & Stchigel, Stud. Mycol. 90: 54 (2017).

Other accepted species: Species Fungorum – search Neopyrenochaeta.
