Dictyoarthrinium sacchari

Ciri dan struktur

Saprobic on dead leaves of Musa sp. Sexual morph: Undetermined. Asexual morph: Colonies compact or effuse, black, often pulvinate. Mycelium superficial, a close network of branched and anastomosing hyphae. Stromata none. Setae and hyphopodia absent. Conidiophores 50–110 × 1–2 μm (x̄ = 72.0 × 1.6 μm, n = 15), basauxic, arising from cup-shaped, brown, distinct conidiophore mother cells, 3.4–4.4 × 2.9–4.7 μm (x̄ = 4 × 3.7 μm, n = 10), macronematous, mononematous, usually straight or flexuous, narrow, cylindrical, rough-walled, subhyaline to pale brown, with dark brown transverse septa as stripes with distances of 6.3–5.8 μm at apex and 2.3–3 μm at base of the conidiophore. Conidiogenous cells 4–4.5 × 4.3–4.7 μm (x̄ = 4.4 × 4.5 μm, n = 10), blastic, integrated, terminal and intercalary, cylindrical, smooth, hyaline. Conidia at maturity 8.5–11.5 × 8.5–10 μm (x̄ = 9.9 × 9.3 μm, n = 40), solitary, dry, acropleurogenous, simple, square, rounded at the corners, 4-celled, but difficult to distinguish the cells due to their blackish-brown nature, spherical or subspherical, often flattened in one plane, blackish-brown at maturity, with brown warts on surface of the cells, terminal conidium always 4-celled or 2-celled, light brown when compared with lateral conidia, most conidia arranged perpendicular to the conidiophore, some directed obliquely upwards. Conidia germinating on PDA within 18 hrs. Colonies on PDA reaching a diameter of 55 mm after 14 days at 25 °C, raised, moderately dense, entire margined, brownish-grey at maturity; reverse white to greyish-white.
