Saprobic on sugary exudates from insects growing on the surface of living leaves. Thallus composed of brown to pale brown, sub-cylindrical, irregularly branched, septate, network-like hyphae. Sexual morph: undetermined. Asexual morph: Conidiomata 120–170 × 20–40 μm, grey-brown, synnematous, gregarious, superficial, arising from aggregated hyphae, differentiated into a basal stalk and a head; stalk 70–130 µm long, 10–40 µm wide, dark brown, base bulbous, comprising parallel hyphae, straight to slightly flexuous, sometimes with helical twisting, branched; head 30–50 μm high, 25–35 μm wide, funnel-shaped, cupulate (Fig. 209 e. j), bearing a conidial hymenium. Conidiomatal wall composed of thick-walled, dark brown to pale brown cells of textura porrecta. Conidiophores arising from the inner layers of pycnidial wall. Conidiogenous cells not observed. Conidia 4–9 × 2.5–4 μm (= 3 × 4 μm, n=30), hyaline, ellipsoid, rounded at both ends, sometimes narrow at the middle part, straight or slightly curved, unicellular, smooth-walled, guttulate.
