Neopseudocercospora
Neopseudocercospora Crous, in Crous et al., Persoonia 31: 219 (2013).
Index Fungorum number: IF 805834; Facesoffungi number: FoF 08523, 2 morphological species (Species Fungorum 2021), 1 species with molecular data.
Foliicolous, plant pathogenic. Mycelium superficial, consisting of branched, septate, medium brown, hyphae, at times constricted at septa, lacking hyphopodia. Sexual morph: Unknown. Asexual morph: Conidiophores solitary, erect, medium brown, subcylindrical, straight to once geniculate, septate. Conidiogenous cells integrated, terminal, medium brown, smooth, subcylindrical, proliferating several times per currently. Conidia solitary, medium brown, smooth, subcylindrical, straight to gently curved, apex obtuse, base truncate, rarely with minute marginal frill, not thickened nor darkened, transversely euseptate (with central pore), rarely with longitudinal septa, guttulate to finely granular, surface finely roughened (adapted from Crous et al. 2013).
Type species: Neopseudocercospora terminaliae Crous
Notes: Neopseudocercospora resembles Sporidesmium, Sporidesmajora and Phaeomycocentrospora (Wu and Zhuang 2005; Yang et al. 2010; Crous et al. 2013a). Sporidesmium, however, belongs to Sordariomycetes, and Phaeomycocentrospora to Pleosporales (Crous et al. 2013a), Sporidesmajora is characterised by long conidiophores, and obclavate conidia with dark basal cells and belongs to Micropeltidaceae while Neopseudocercospora belongs to Mycosphaerellaceae (Yang et al. 2010; Crous et al. 2013). Within Mycosphaerellaceae, Neopseudocercospora resembles Pseudocercospora (Crous et al. 2013a), but Neopseudocercospora is unique in having superficial hyphae, solitary conidiophores, conidiogenous cells that proliferate percurrently, and conidia that have transverse septa and these characters are absent in Pseudocercospora. Molecular markers available for Neopseudocercospora are LSU and ITS.
