Associated with leaf spot. Sexual morph: Unknown. Asexual morph: Stromata small, flat, subcuticular, pseudoparenchymatous, carbonaceous, with a vertically arranged successive structure, with a single locus, cover one-layered, irregularly splitting, basal layer pseudoparenchymatous below and palisade-like above. Conidiophores reduced to conidiogenous cell. Conidia pigmented, 2-celled, solitary, separated from the tips of the internal palisade like cell layer by a horizontal septum (adapted from von Höhnel 1918 and Videira et al. 2017).
Type species: Didymochora betulina Höhn.
Notes: Didymochora is characterised by flat, subcuticular, pseudoparenchymatous stromata, and pigmented, 2-celled, solitary conidia. The placement of Didymochora in Mycosphaerellaceae is doubtful. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Didymochora.
