Balladyna Racib., Parasit. Alg. Pilze Java's (Jakarta) 2: 6 (1900).

 Index Fungorum number: IF 502; Facesoffungi number: FoF 07868, 35 morphological species (Species Fungorum, 2022), molecular data unavailable.

Parasitic on living leaves. Sexual morph: Ascomata superficial, formed on hyphae, with a subiculum, solitary, scattered, globose to subglobose, with apical pore, minutely pedicellate at the base, olivaceous brown to dark brown, with transparent wall, surrounded by a superficial mycelium network, branched, septate, with several dark brown, knob-like hyphopodia, bearing dark setae. Peridium 3–5 µm wide, comprising 1–2 layers of olivaceous-brown cells of textura angularis, lacking pseudoparaphyses. Asci 8-spored, bitunicate, with a single ascus, globose to subglobose, sessile. Ascospores multi-seriate in the ascus, ellipsoid, upper cell wider,uniseptate, hyaline to light brown when immature, fawn to olivaceous brown, smooth-walled to slightly ornamented. Asexual morph: hyphomycetous, Clasterosporium sp., Tretospora sp. (Thaung 1976; Kirk et al. 2008; Seifert et al. 2011).


Type species: Balladyna gardeniae Racib
