Laburnicola gen. nov., with four new species, Paramassariosphaeria gen. nov., with a new species and Montagnula saikhuensis sp. nov. are introduced in this paper. The phylogeny of these taxa and genera of Didymosphaeriaceae are resolved based on analysis of combined LSU, SSU, and ITS sequence data. Laburnicola is characterized by obpyriform, immersed ascomata, with a peridium fused to the host tissues, long pedicellate asci and ellipsoidal to fusoid ascospores, whose central cells have longitudinal septa and a rugged surface. Paramassariosphaeria is characterized by globose to subglobose ascomata, papillate ostioles, a peridium comprising pseudoparenchymatous cells of textura angularis, cylindric-clavate to clavate, pedicellate asci and brown, curved-fusoid ascospores, with multiple transverse septa and a mucilaginous sheath. Montagnula saikhuensis has immersed ascomata, with a peridium fused to the host tissues, long pedicellate asci and blackish brown, ellipsoidal ascospores with a single septum. The relationship of these taxa with other Didymosphaeriaceae species is discussed based on comparative morphology and phylogenetic analysis. Munkovalsaria appendiculata and Munkovalsaria donacina are transferred to the genus Montagnula.
