Ciri dan struktur
Associated with leaf spots on Cycas (Cycadaceae). Sexual morph Undetermined. Asexual morph Conidiomata 130–170 μm high, 180–270 μm diam., pycnidial, semi-immersed, visible as raised, black dots on host surface, scattered, solitary to gregarious, globose to subglobose, glabrous, uni-loculate, ostiolate at centre, with minute papilla, lacking periphyses. Conidiomata walls 10–20 μm, thin-walled, of equal thickness, composed of 3–5 layers, of flattened, brown to dark brown, pseudoparenchymatous cells, with blackened cells at the papilla, arranged in textura angularis to textura prismatica, difficult to distinguish from conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (2.5–)3–5(–8) × (1.5–)2–5(–7) µm (\(\bar{x} \) = 4.3 × 3.7 μm, n = 30), holoblastic, phialidic, hyaline, smooth, aseptate, ampulliform, arising from the inner cavity of the conidioma wall. Conidia (8–)10–13(–14) × 3–4 µm (\(\bar{x} \) = 12 × 4.2 μm, n = 50), initially light brown, becoming reddish-brown to brown, oblong to ellipsoidal, or subclavate with truncate base, 3-septate, not constricted at the septa, smooth-walled. Culture characteristics: Colonies on PDA reaching 10–15 mm diam. after 10 days at 25–30 °C; from above, white to cream at the margin, grey at the centre; from below, white to cream at the margin, black at the centre; medium dense, circular, slightly raised, surface slightly smooth, with edge entire, fluffy to feathery; not producing pigmentation in agar.
