Based on phylogenies of ITS, LSU, RPB2, TEF-1α and TUB sequences, Quaedvlieg et al. (2014) introduced Queenslandipenidiella as a monotypic genus within Teratosphaeriaceae, Mycosphaerellales in Dothideomycetes with the type species Queenslandipenidiella kurandae. The type species of this genus initially placed in Penidiella, with Penidiella kuranda as the type species deal to penicillate conidiophores that produce brown conidia with inconspicuous hila (Crous et al. 2007a). Subsequently, Quaedvlieg et al. (2014) reported that Queenslandipenidiella can be distinguished from Penidiella s.str. by its well-defined penicillate conidiophores, with clear branching structure, which is less apparent in species of Penidiella s.str. (Crous et al. 2007b). Queenslandipenidiella is named after its occurrence in Queensland, Australia, and its morphological similarity to the genus Penidiella. Species of Queenslandipenidiella are characterized by consisting of brown, thick-walled, branched, hyphae, smooth mycelium; macronematous conidiophores, erect, arising from superficial hyphae, branching penicillate, septate; conidiogenous apparatus consisting of several sets of branches; doliiform to subcylindrical conidiogenous cells, brown, smooth, with 1–2 apical scars that are flattened; brown ramoconidia, smooth-walled, with 2–3 apical loci, narrowly ellipsoidal to subcylindrical; conidia occurring in short chains, brown, smooth, ellipsoidal, apex obtuse, base subtruncate with or without a flattened inconspicuous hilum (Quaedvlieg et al. 2014). Currently, two species are recorded in this genus.
