Type speciesXenopyrenochaetopsis pratorum (P.R. Johnst. & Boerema) Valenz.-Lopez, Crous, Stchigel, Guarro & Cano, Stud. Mycol. 90: 62 (2017).

Phoma pratorum P.R. Johnst. & Boerema, N.Z. Jl Bot. 19(4): 395 (1982).

Notes – Phylogenetically, Valenzuela-Lopez et al. (2018) indicated that Pyrenochaetopsis pratorum clustered outside Pyrenochaetopsis sensu stricto. Therefore, Xenopyrenochaetopsis was established to accommodate Xenopyrenochaetopsis pratorum (= Pyrenochaetopsis pratorum). Xenopyrenochaetopsis is characterized by pale brown to brown, solitary or confluent, glabrous, globose pycnidium, with ostiolate, wall comprises textura angularis cells, phialidic, hyaline conidiogenous cells, cylindrical, aseptate, hyaline, smooth- and thin-walled conidia, with guttulate (Valenzuela-Lopez et al. 2018).
