Based on DNA sequencing and morphological analyses, Quaedvlieg et al. (2014) introduced Eupenidiella within Teratosphaeriaceae in Mycosphaerellales with the type species E. venezuelensis. Eupenidiella is a monotypic genus, and characterized by smooth to finely verruculose, septate, branched, pale olivaceous to medium brown hyphae mycelium, subcylindrical, septate, straight to flexuous to once geniculate, terminally penicillate, branched portion composed of true branchlets and/or a single set or several sets of ramoconidia conidiophores, unbranched, with 1–3(–4) flat-tipped, darkened-refractive loci, terminal and intercalary conidiogenous cells, finely verruculose, in branched chains, ramoconidia 0–1(–3)-septate, secondary conidia 0(–1)-septate, hila sometimes slightly thickened and darkened-refractive conidia (Quaedvlieg et al. 2014). Morphologically, Eupenidiella is similar to Penidiella but differs in having dimorphic conidiophores, subdenticulate conidiogenous loci, and slightly darkened-refractive (Quaedvlieg et al. 2014). Currently, only one species (Eupenidiella venezuelensis, type species) has been described from the man of the tinea nigra in Venezuela (Quaedvlieg et al. 2014).

Type species: Eupenidiella venezuelensis (Crous & U. Braun) Quaedvl. & Crous
