Ciri dan struktur
Associated with leaf spots of Nypa fruticans. Leaf spots necrotic, initially round, then expand and elongate to irregularly oval, brown with a darker brown margin. Asexual morph: On alfalfa stem on WA: conidiomata pycnidia 220–460 μm diam., solitary or aggregate, semi-immersed to submerged, black, sub-globose to globose, ostiolate with abundant pale white conidial cirri. Conidiophores 12.5–24.5 × 1.5–3.2 μm (20.2 ± 2.3 × 2.1 ± 0.5 μm, n = 30, l/w: 9.6), hyaline, cylindrical, septate, unbranched, straight, or slightly curved, tapering towards the apex. Conidiogenous cells, 5.5–9 × 1.4–2.2 μm (7.8 ± 0.8 × 1.9 ± 0.2 μm, n = 30, l/w: 4.1), aseptate, hyaline, ellipsoidal to fusoid, and eguttulate. Alpha conidia 6.5–10.5 × 2–3.2 μm (8.2 × 2.5 μm, n = 50, l/w: 3.3), aseptate, hyaline, ellipsoidal to fusoid, multi-guttulate, base acute to acuminate. Beta conidia and gamma conidia not observed. Sexual morph: Not observed. Colonies on PDA media, reaching 52.5 mm, when incubated at room temperatures (28 ± 2 °C) for 7 days, produce three morphotypes: a) white, flat, filamentous, sparse aerial mycelium with circular and irregular margin, and reverse is orange yellow with visible submerged conidiomata; b) white, flat with entire margin, and reverse is yellow; c) gray, flat, floccose to woolly with entire margin and reverse is pale gray with concentric darker gray zones radiating from the center.
