Balladynocallia
Balladynocallia Bat., in Batista, Silva & Bezerra, Atas Inst. Micol. Univ. Pernambuco 2: 216 (1965).
Index Fungorum number: IF 505; Facesoffungi number: FoF 07951, 3 morphological species (Species Fungorum 2022), no molecular data available.
Parasitic on living leaves. Colonies amphigenous, dark pigmented, up to 3 mm diameter, superficial mycelium and hyphopodia, pale brown, branched, densely reticulate, with somewhat undulating hyphae, up to 4 µm thick, lacking setae. Hyphopodia unilateral to alternate, concolourous with hyphae, continuous, ovoid, hemispherical to irregular. Sexual morph: Ascomata densely dispersed, subglobose to ovate, with an irregular apical pore, glabrous, black, numerous, short-stalked, lacking pseudoparaphyses. Peridium 4–6 µm wide, comprising brown cells of textura angularis, with granular appearance. Asci 8-spored, bitunicate, with 2–6-asci in ascoma, broadly ellipsoid to saccate, sessile, upper cell wider and rounded, narrower towards the lower end. Ascospores multi-seriate, ovoid to obovoid, upper cell wider, narrower towards the lower and rounded end, uniseptate, somewhat unequally, dark brown. Asexual morph: Unknown (adapted from Boonmee et al. 2017).
Type species: Balladynocallia glabra (Hansf.) Bat.
Notes: Balladynocallia is characterised by continuous, ovoid, hemispherical to irregular hyphopodia, subglobose to ovate ascomata, broadly ellipsoid to saccate asci and ovoid to obovoid,uniseptate ascospores. Sivanesan (1981) added B. magna to Balladynocallia based on morphology. Boonmee et al. (2017) examined the holotype specimen of Balladynocallia glabra (K (M) 177971 = ex herb. IMI 5081a) but the specimen was not in good condition. Boonmee et al. (2017) referred Balladynocallia to Balladynaceae based on Sivanesan’s (1981) descriptions and illustrations. We re-examined the isotype specimen from GZU but the specimen was in poor condition and no asci and ascospores could be observed. Balladynocallia is a distinct genus in Balladynaceae but fresh collections with DNA sequence data are needed to confirm the taxonomic placement of the genus.
