Type – Pseudopyrenochaeta Valenz.-Lopez, Crous, Stchigel, Guarro & Cano
Notes – In the phylogenetic analysis of Valenzuela-Lopez et al. (2018), the type species of Pyrenochaeta (P. nobilis) was distant from Cucurbitariaceae and did not group with strains of Pyrenochaeta lycopersici and P. terrestris. Therefore, Valenzuela-Lopez et al. (2018) treated Pyrenochaeta nobilis as species incertae sedis and transferred P. lycopersici and P. terrestris to the new genus Pseudopyrenochaeta. They also introduced Pseudopyrenochaetaceae to accommodate Pseudopyrenochaeta (Valenzuela-Lopez et al. 2018).
