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. Conidiophores solitary, erect, medium brown, subcylindrical, straight to once geniculate, septate. Conidiogenous cells integrated, terminal, medium brown, smooth, sub cylindrical, proliferating several times per currently. Conidia solitary, medium brown, smooth, sub cylindrical, 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 was introduced by Crous et al. (2013) with N. terminaliae as type species. Neopseudocercospora resembles Sporidesmium, Sporidesmajora and Phaeomycocentrospora (Wu and Zhuang 2005; Yang et al. 2010; Crous et al. 2013a). Sporidesmium, however, belongs to the Sordariomycetes, and Phaeomycocentrospora to the Pleosporales (Crous et al. 2013a), Sporidesmajora is characterized by long conidiophores, and obclavate conidia with dark basal cells and belongs to the Micropeltidaceae while Neopseudocercospora belongs to the 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 longitudinal septa and these characters are absent in Pseudocercospora.
