Index Fungorum number: IF 817646; Facesoffungi number: FoF 08232, 2 morphological species (Species fungorum 2021), 2 species with molecular data.
Isolated from soil. Sexual morph: Unknown. Asexual morph: Hyphae pale to dark brown, smooth- and thin- to thick-walled, septate. Pycnidia brown to dark brown, globose, solitary, pycnidial wall of textura angularis, neck absent, ostiolated or not. Conidiogenous cells enteroblastic, phialidic, globose to flask-shaped, hyaline, thin-walled. Conidia hyaline, cylindrical, 1-septate, guttulate. Chlamydospores absent (Adapted from Crous et al. 2016).
Type species: Pseudoascochyta pratensis Valenzuela-Lopez, Cano-Canals, Stchigel, Guarro & Cano
Notes: Pseudoascochyta resembles Ascochyta but can be differentiated based on DNA sequence data. Pseudoascochyta differs from Ascochyta in having typically lower growth rate on OA, the absence of crystal production, larger conidia and the number of septa. Phylogenetically, Pseudoascochyta is a distinct and well-supported genus in Didymellaceae. Molecular markers available for Pseudoascochyta are ITS, LSU, BTUB and RPB2.
