Apenidiella Quaedvl. & Crous, in Quaedvlieg et al., Persoonia 33: 28 (2014).
Saprobic on host substrate. Sexual morph: Unknown. Asexual morph: Mycelium consisting of branched, septate, smooth, hyaline to pale olivaceous, hyphae, sometimes constricted at dark septa. Conidiophores solitary, erect, arising from superficial mycelium, reduced to conidiogenous cells or macronematous, subcylindrical, straight to slightly curved, sometimes attenuated towards the apex, septate, medium brown, smooth, apex with a terminal conidiogenous cell giving rise to a single set of ramoconidia. Conidiogenous cells terminal, integrated, subcylindrical, straight, pale brown, thin-walled, smooth, apex obtusely rounded to somewhat clavate; loci terminal, occasionally sub terminal or lateral, unthickened to slightly thickened and darkened, not refractive. Conidia in branched chains; ramoconidia subcylindrical, with 1–3 terminal loci, olivaceous-brown, smooth; secondary conidia ellipsoidal, with one side straight and the other convex, straight to slightly curved, sub hyaline to olivaceous-brown, smooth, thin-walled; hila unthickened to slightly thickened and darkened, not refractive (adapted from Quaedvlieg et al. 2014).
Type species: Apenidiella strumelloidea (Milko & Dunaev) Quaedvl. & Crous
Notes: Apenidiella is characterised by conidiophores with a solitary conidiogenous cell that gives rise to a single set of ramoconidia. Ramoconidia and conidia are aseptate, smooth and thin-walled, subhyaline to olivaceous-brown. Apenidiella is morphologically and phylogenetically a distinct genus in Teratosphaeriaceae. Molecular markers available for Apenidiella include ITS, LSU and RPB2.
