Ciri dan struktur
Description: Life style: Parasitic, leaves of Rosa sp. (Rosaceae). Asexual morph: Conidiomata erumpent, separated, immersed or superficial, globose to depressed, initially appearing deep brown to black, slowly oozing transparent white or pale-yellow oily spheres with age, up to 600 µm diam., 5–7 wall layers of olive brown to brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, hyaline, smooth, subcylindrical, branched at base or not, frequently branched above, simple, tapering, hyaline, smooth, subcylindrical, tapering towards apex, 6–15 × 1–3.5 µm (x ¯ = 11 × 2 µm; n = 20). Conidia solitary, aseptate, fusoid, hyaline, asymmetrical, guttulate, smooth-walled, rounded to acute apex, 6–12 × 2–4 µm (x ¯ = 8.5 × 3 µm; n = 30). Sexual morph: Unknown. Culture characteristics: Colonies cultured at 25 °C and a 12 h light/dark regime for 2 weeks on PDA 60–85 mm diam., forming a circle of transparent mycelium in the center, followed by a circle of white or gray-white thick ridges, then uneven zonated aerial mycelium, slightly imbricated, thick, initially appearing white to pale yellow, slowly turning olive-gray with age outside the two concentric rings, with an uneven edge; reverse transparent to white or olive and white uneven imbricated zonated to white or light brown uneven edge. Colonies on OA covering the whole dish, pale white or light gray-white, flat surface, exuding deep brown to black conidial masses, slowly oozing transparent white or pale-yellow oily spheres with age, reverse pale white or light gray-white.
