Quaedvlieg et al. (2014) introduced Neopenidiella within Mycosphaerellaceae, Mycosphaerellales, Dothideomycetidae in Dothideomycetes with the type species Neopenidiella nectandrae. Neopenidiella is a monotypic genus characterized by straight, filiform, pluriseptate throughout, thin-walled, smooth, brown, darker below and paler above, apex penicillate, long conidiophores, apically truncated, conical, subdenticulate, slightly darkened-refractive, mostly unthickened conidiogenous, aseptate, barely or distinctly attenuated at the truncate base, with 2–3(–4) subdenticulate hila at the apex, subcylindrical, thin-walled, smooth to faintly verruculose ramoconidia, long acropetal chains, pale olivaceous to olivaceous-brown or brown, narrowly ellipsoid-ovoid, fusiform to cylindrical aseptate, smooth to faintly rough-walled, thin-walled conidia (Quaedvlieg et al. 2014). Currently, only one species (Neopenidiella nectandrae, type species) has been described from the living leaves of Nectandra coriacea (Lauraceae) in Cuba (Quaedvlieg et al. 2014).

Type species: Neopenidiella nectandrae (Crous, U. Braun & R.F. Castañeda) Quaedvl. & Crous.

Other accepted species: This genus is monotypic.
