Diversimediispora was established by Liu et al. (2019), based on morphology and phylogenetic analyses of combined LSU, ITS, tub2, tef1-α, and rpb2 sequence data. The type species D. humicola was isolated from soil in the USA. Diversimediispora has discrete cylindrical or ampulliform, colorless, smooth conidiogenous cells. The conidia were fusoid euseptate with basal obconic cells, trapezoid doliiform median cells, and conic apical cell-bearing thin-walled, colorless appendages. Diversimediispora produces conidia with versicolourous median cells, where the second and third cells (from the apex) are darker, distinguishing it from other genera in Sporocadaceae. No additional species have been introduced since the establishment of Diversimediispora in Species Fungorum (2024). 

Type species: Diversimediispora humicola F. Liu, L. Cai & Crous
