Classification: Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi
Plant pathogen, parasitic on roots. Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata pycnidial, solitary, setose, globose to subglobose, brown to dark brown, papillate, ostiolate. Conidiophores simple, filiform, septate. Conidiogenous cells phialidic, intercalary, disposed along the conidiophores as short side projections. Conidia cylindrical to allantoid, hyaline, aseptate, smooth- and thin-walled.
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).
Type species: Pseudopyrenochaeta Valenz.-Lopez, Crous, Stchigel, Guarro & Cano
