Crous et al. (2017) introduced Pseudodactylariaceae to accommodate a single genus, Pseudodactylaria (Ps.), based on the morphology and an LSU phylogenetic tree within Pseudodactylariales. Their phylogenetic analysis showed that Vermiculariopsiellaceae from Vermiculariopsiellales and Chaetosphaeriaceae from Chaetosphaeriales were the closest clades to this family. Currently, there is only one genus, Pseudodactylaria, with 20 accepted species in Pseudodactylariaceae (Crous et al. 2017, Hyde et al. 2024). The family is characterized by hyaline, smooth, branched, septate hyphae, erect, hyaline, smooth, subcylindrical, straight to flexuous, unbranched, thick-walled, septate conidiophores and terminal, integrated, subcylindrical conidiogenous cells with apical taper. The apical part forms a rachis with numerous aggregated cylindrical denticles, and the scars are cicatrized, not thickened or darkened. Conidia are solitary or aggregated in slimy masses, fusoid-ellipsoid, hyaline, smooth, surrounded by a thin mucilaginous sheath, guttulate, and 1-septate at the middle.
Type genus: Pseudodactylaria Crous, in Crous et al., Persoonia 39: 421 (2017)
