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, 1-septate, 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
Notes: Balladyna was introduced by Raciborski (1900) based on the species of B. gardeniae. Balladyna is unique in having ascomata formed on hyphae, mycelium with hyphopodia-like structures, lack pseudoparaphyses and presence of single ascus in each ascomata. Fresh collections with DNA sequence data are needed to confirm the taxonomic placement of Balladyna.
