Pyrenochaetopsis was introduced to accommodate phoma-like species with setose pycnidia (de Gruyter et al. 2010). This genus is characterized by setose pycnidia which are similar to Pyrenochaeta based on phoma-like conidiogenesis but they are can distinguished by molecular data (de Gruyter et al. 2010). Previously, Pyrenochaetopsis was in Cucurbitariaceae (de Gruyter et al. 2010, 2013, Hyde et al. 2013). However, it was included in Pyrenochaetopsidaceae by Valenzuela-Lopez et al. (2018).

Type species: Pyrenochaetopsis leptospora (Sacc. & Briard) Gruyter, Aveskamp & Verkley.

Other accepted species: Species Fungorum – search Pyrenochaetopsis.
