Sexual morph: Ascomata superficial, scattered, gregarious between veins, uniloculate, subglobose to globose, with short stalk when mature, smooth or verrucose, black, with blackened fungal tissue in the leaf below stalk. Central ostiole with periphyses. Peridium thick-walled, comprising brown to dark brown cells of textura angularis at outer layer, and pale brown, flattened cells towards the inner layer. Hamathecium comprising irregular pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical to clavate, with broad, with lobed pedicel, apically rounded with ocular chamber. Ascospores overlapping 1–2-seriate, fusoid to ellipsoidal, brown to dark brown, 1-septate, constricted at septum, inequilateral, upper cell broader and longer than lower cell, slightly narrowed at the ends, smooth-walled or striate, lacking a mucilaginous sheath. Asexual morph: Coelomycetous, assumed as Ascochytopsis. Conidiomata thick-walled, black. Conidiogenous cell cylindrical, proliferating percurrently. Conidia straight to falcate, hyaline, aseptate (Sivanesan 1984; Cannon and Kirk 2007; Hyde et al. 2013).

Type: Parodiella Speg.

Notes: Parodiellaceae was invalidly introduced by Theissen and Sydow (1918) and was validated by Barr (1987b). Hyde et al. (2013) provided an updated description based on the syntype of Parodiella hedysari (K(M) 176017) from Kew collection to represent Parodiellaceae. Parodiellaceae comprises a single genus, Parodiella and is treated as Doth- ideomycetes families incertae sedis (Wijayawardene et al. 2018). Sequence data is not available for this family.
