Pseudopyrenochaeta Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, in Valenzuela-Lopez et al., Stud. Mycol. 90: 53 (2017).
MycoBank number: MB 820427; Index Fungorum number: IF 820427; Facesoffungi number: FoF 08353; 2 morphological species (Species Fungorum 2020), 2 species with molecular data.
Type species – Pseudopyrenochaeta lycopersici (R.W. Schneid. & Gerlach) Valenz.-Lopez, Crous, Stchigel, Guarro & J.F. Cano.
Notes – 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.
