Phaeocercospora Crous, in Crous et al., Persoonia 28: 171 (2012).
Index Fungorum number: IF 800386; Facesoffungi number: FoF 08540, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Foliicolous, associated with leaf spots. Sexual morph: Unknown. Asexual morph: Caespituli amphigenous, subepidermal, arising from subepidermal, globular fruiting bodies (immature structures with undefined white contents). Peridium comprising wall of 2–3 layers of textura angularis, bursting through epidermis, forming grey sporodochia with densely aggregated conidiophores. Conidiophores subcylindrical to ampulliform, brown, finely verruculose, aggregated, 0–2-septate. Conidiogenous cells terminal, brown, finely verruculose, ampulliform, tapering to a truncate apex, proliferating several times percurrently at apex (proliferations irregular, rough). Conidia solitary, brown, finely verruculose, guttulate, subcylindrical to narrowly obclavate, straight to mildly curved, apex sub obtuse, base truncate with marginal frill, transversely septate; hila and scars not thickened, nor darkened or refractive (adapted from Crous et al. 2012).
Type species: Phaeocercospora colophospermi Crous
Notes: Phaeocercospora morphologically resembles Pseudocercospora, Scolecostigmina, and Cercostigmina but is phylogenetically distinct. Phaeocercospora is a distinct genus in Mycosphaerellaceae. Molecular markers available for Pseudocercospora include ITS, LSU, Actin, Calmodulin, Histone, RPB2 and TEF-1.
