Type species – Acrocordiella occulta (Romell) O.E. Erikss.
Notes – Acrocordiella is characterised by solitary or small groups of immersed ascomata with white or black margins, a peridium comprising brown to hyaline, thick-walled cells of textura angularis and 3-distoseptate ascospores with rhomboid lumina. This genus has been considered a synonym of Requienella (Boise 1986). Wijayawardene et al. (2018a) listed Acrocordiella in Pyrenulaceae. However, Jaklitsch et al. (2016b) and Maharachchikumbura et al. (2016b) confirmed Acrocordiella and Requienella as distinct genera of Requienellaceae in Xylariales (Sordariomycetes) based on phylogenetic analyses.
