Colletotrichum karsti

Ciri dan struktur

Isolated from a leaf spot of Rosa chinensis Jacq. Sexual morph: undetermined. Asexual morph: Conidiomata pycnidial, globose, dark brown, superficial on PDA, releasing conidia in a yellow mass, slimy, globose. Conidiophores produce conidiogenous cells, either directly formed from hyphae or from a cushion of spherical hyaline cells, septate, and branched. Conidiogenous cells hyaline, cylindrical to clavate, straight to flask-shaped, (17.4–)18–50(–53.2) × (3.2–)4–5(–5.8) μm (mean ± SD = 33 ± 0.9 × 4 ± 0.2 μm). Setae not observed. Conidia (12.6–)13–14.8(–15) × (6.2–)6.3–7.9(–8.4) μm (mean ± SD = 14 ± 0.8 × 7 ± 0.2 μm), n = 30, L/W ratio = 2.1, hyaline, aseptate, smooth-walled, ellipsoidal to cylindrical, one end rounded and one end acute or both ends rounded, sometimes the base slightly pointed with a prominent scar, guttulate, granular. Appressoria single in short chains, pale brown, thick-walled, entire edge, rarely lobate, smooth-walled. Colonies on PDA reach 5 cm in diameter after 7 days at room temperature (±25 °C), exposed to 12 hours of light and 12 hours of darkness. The colonies are rhizoid to filamentous, dense, with a filamentous margin. After 14 days, the colony appears white to pale-yellow from above, producing grouped dark brown pycnidia and a white to yellow reverse (Fig. 5a, b).
