MycoBank number: MB 553830; Index Fungorum: IF 553830; Facesoffungi number: FoF 06396, 2 species.
Parasitic on living leaves. Sexual morph: Colonies form on a lower surface of leaves, black, subcircular, with outwardly radiating mycelium, with hyphae that are long hairy, flexible, dark brown to black, densely, fluffy, par- tially erect, unbranched, and septate. Ascomata superficial, globose to subglobose, black, seated on dark hyphae, covered by dense hyphae, superficial mycelium, unbranched, septate, dark to black. Peridium comprising dark brown to black cells of textura angularis. Hamathecium comprising elongate-filiform, septate, unbranched, filamentous, cellular pseudoparaphyses, extending over asci, constricted at the septa. Asci 8-spored, bitunicate, fissitunicate, saccate-oblong to ellipsoidal, sessile, lower median widest, with the small ocular chamber. Ascospores 2–3-seriate, ellipsoid-fusiform, end narrow, pigmented, multi-septate. Asexual morph: Undetermined.
Type: Hyalomeliolina F. Stevens.
Notes: Boonmee et al. (2017) re-examined the type species Hyalomeliolina guianensis and concluded the unique suite of characters and could not place it in any families in Dothideomycetes. Therefore, Hyalomeliolinaceae was established to accommodate Hyalomeliolina (Boonmee et al. 2017). No molecular data is available to confirm its phylogenetic placement within Dothideomycetes.
