Abraham, Nova Hedwigia 80: 486, 2005 (Fig.47).Colonies mostly hypophyllous, dense, velvety, upto 5mm diam., confluent. Hyphae straight to flexuous,branching mostly opposite at acute angles, loosely toclosely reticulate, cells 12–16x5–7 μm. Appressoriaalternate, about 30% opposite, antrorse to subantrorse,12–16 μm long; stalk cells cylindrical to cuneate, 3–5μm long; head cells predominantly globose, rarelyovate, entire, 9–11x8–11 μm. Phialides few, mixed withappressoria, alternate to opposite, ampulliform, 16–20x8–11 μm. Mycelial setae densely scattered, simple,straight to flexuous to arcuate, obtuse to acute at the tip,up to 300μm long. Perithecia scattered, up to 175μmdiam.; ascospores obovoidal to cylindrical, 4-septate,slightly constricted at the septa, 33–40x12–15 μm.Material examined: 12.xii.2003 on leaves of Maesaindica (Roxb.)
