Exopassalora Videira & Crous, in Videira et al., Stud. Mycol. 87: 380 (2017).
Index Fungorum number: IF 822829; Facesoffungi number: FoF 07641, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Foliicolous, pathogenic. Sexual morph: Unknown. Asexual morph: Mycelium composed of brown hyphae, smooth to rough, irregularly branched, septate, with dark brown chlamydospore-like hyphal swellings. Conidiophores arising from the mycelium, medium brown, smooth, simple or branched, straight to curved. Conidiogenous cells terminal and intercalary, mono- to polyblastic subcylindrical, pale to medium brown, smooth, proliferating sympodially, conidiogenous loci conspicuous, darkened, refractive. Conidia catenate, in simple or branched chains, medium brown, smooth, narrowly ellipsoidal, tapering to sub truncate, straight or slightly curved, hila slightly thickened and darkened (adapted from Videira et al. 2017).
Type species: Exopassalora zambiae (Crous & T.A. Cout.) Videira & Crous
Notes: Exopassalora resembles Passalora but is phylogenetically distinct. Exopassalora is a well-supported genus in Mycosphaerellaceae. Molecular markers available for Exopassalora are ITS, LSU, SSU, actin, Btub, Calmodulin, RPB2 and TEF-1.
