Neopenidiella Quaedvl. & Crous, in Quaedvlieg et al., Persoonia 33: 22 (2014).
Index Fungorum number: IF 807778; Facesoffungi number: FoF 08521, 1 morphological species (Species Fungorum 2021), molecular data unavailable.
Foliicolous. Sexual morph: Unknown. Asexual morph: Conidiophores erect, straight, filiform, pluriseptate throughout, brown, darker below and paler above, thin-walled, smooth, apex penicillate, terminal cell of the conidiophore with short denticle-like loci giving rise to sets of conidiogenous cells or ramoconidia that then form a sequence of new sets of ramoconidia on different levels. Conidiogenous loci terminal or sub terminal, usually 1–3(–4), sub denticulate, conical, apically truncate, unthickened or almost so, not to somewhat darkened-refractive. Ramoconidia with truncate base, barely or distinctly attenuated at the truncate base, aseptate, at the apex with 2–3(–4) sub denticulate hila, sub cylindrical, very pale olivaceous, olivaceous brown to brown, thin-walled, smooth to faintly verruculose. Conidia in long acropetal chains, narrowly ellipsoid-ovoid, fusiform to cylindrical aseptate, very pale olivaceous, olivaceous brown to brown, thin walled, smooth to very faintly rough-walled; hila unthickened or almost so, at most slightly darkened-refractive (Adapted from Quaedvlieg and Crous 2014).
Type species: Neopenidiella nectandrae (Crous, U. Braun & R.F. Castañeda) Quaedvl. & Crous
Notes: Neopenidiella was introduced by Quaedvlieg and Crous (2014) with N. nectandrae as type species. Neopenidiella differs from Penidiella in having conidiophores that are long and filiform, with a subdenticulate apical cell where long and narrow penicillate ramoconidia are formed. In the phylogenetic analysis of Videira et al. (2014), Neopenidiella forms a distinct lineage within Mycosphaerellaceae.
