Type species: Pseudoascochyta pratensis Valenzuela-Lopez, Cano-Canals, Stchigel, Guarro & Cano


Notes: Pseudoascochyta was introduced by Valenzuela-Lopez et al. (2016). Pseudoascochyta is characterized by pale to dark brown hyphae, brown to dark brown pycnidia, globose to flask-shaped conidiogenous cells, hyaline, cylindrical, 1-septate conidia. Pseudoascochyta resembles Ascochyta but can be differentiated based on DNA sequence data (Chen et al. 2015).  Pseudoascochyta is a well-separated and distinct genus in Didymellaceae.
