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, partially 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-iliform, 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: Unknown (adapted from Boonmee et al. 2017).
Type species: Hyalomeliolina guianensis F. Stevens
Notes: Boonmee et al. (2017) examined the type species Hyalomeliolina guianensis and placed Hyalomeliolina in a new family Hyalomeliolinaceae based on morphological characters. Fresh collections with DNA sequence data are needed to confirm the systematic position of Hyalomeliolina.
