Semipseudocercospora J.M. Yen, Mycotaxon 17: 361 (1983).

Index Fungorum number: IF 25847; Facesoffungi number: FoF 08655, 2 morphological species (Species Fungorum 2022), no molecular data available.

Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Hyphomycetous. Conidiogenous loci distinctly denticle-like and hila unthickened, undarkened. Conidiogenous cells not geniculate, not clearly sympodially proliferating. Conidia solitary, didymo- to phragmosporous, not scolecosporous (adapted from Videira et al. 2017).


Type species: Semipseudocercospora peristrophes-acuminatae (J.M. Yen) J.M. Yen


Notes: Semipseudocercospora is characterised by unthickened, undarkened conidiogenous loci and hila, not geniculate conidiogenous cells, and didymo- to phragmosporous conidia. Semipseudocercospora is morphologically similar to Pseudocercospora but its phylogenetic position is uncertain. The placement of Semipseudocercospora in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Semipseudocercospora.
