Plenodomus changchunensis

Ciri dan struktur

Description: Saprobic on dead stems of Poaceae. Sexual morph: Undetermined. Asexual morph: Conidiomata 163–192 × 193–245 μm (x = 175 × 207 μm, n = 5), pycnidial, solitary or in groups of 2–5, erumpent, aggregated, globose to subglobose, depression in the middle, thick-walled, subcoriaceous to coriaceous at the outer layers, dark brown to black, ostiolate. Ostioles 20–45 μm, central, papillate, ovoid, filled with short periphyses. Conidiomatal wall 24–48 μm wide, thick, multilayered, outer layer composed of 8–10 layers of dark brown to brown cells of textura angularis, lined with a thick hyaline layer bearing conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 2.8–5.8 × 1.5–2.8 μm (x = 4.1 × 2 μm, n = 30), enteroblastic, phialidic, determinate, smooth-walled, hyaline. Conidia 5–7.6 × 2–3.4 μm (x = 6.2 × 2.7 μm, n = 50), oblong or oval, slightly curved toward the ends, rounded ends, aseptate, hyaline, smooth-walled. Culture characteristics: Colonies on PDA reaching 30 mm diam. after 3 weeks at 25 °C. Cultures from above, gray in the center, milky white radiating outward, dense, circular, creeping hyphae, grayish-green at the margins; reverse dark at the center, milky white radiating outward. Yellow pigmentation diffused into the media.
