Pseudopyrenochaeta was introduced based on the phylogenetic analyses by Valenzuela-Lopez et al. (2018). The strain of the type species (CBS 306.65) was treated as Pyrenochaeta lycopersici and its phylogenetic placement was located in Cucurbitariaceae (de Gruyter et al. 2010). de Gruyter et al. (2013) placed it as incertae sedis. Valenzuela-Lopez et al. (2018) indicated that P. lycopersici forms a distinct lineage outside Cucurbitariaceae and as a new genus Pseudopyrenochaeta. They also introduced Pseudopyrenochaetaceae to accommodate this new genus.
Type species: Pseudopyrenochaeta lycopersici (R.W. Schneid. & Gerlach) Valenz.-Lopez, Crous, Stchigel, Guarro & J.F. Cano.
Other accepted species: Species Fungorum – search Pseudopyrenochaeta.
