Cercospora arachidicola

Ciri dan struktur

Leaf spots amphigenous, subcircular to angular-irregular, 2.5–9.5 mm diam., greyish brown to medium dark brown, occasionally limited by veins, margin indefinite. Caespituli epiphyllous, whitish brown to greyish brown. Mycelium mainly internal. Internal hyphae pale brown, smooth, 1.5–3 μm wide. Stromata small, up to approx. 32 μm diam., embedded in the mesophyll or in substomatal chambers, subcircular to irregular, brown to dark brown. Conidiophores in small, loose to moderately dense fascicles, arising from internal hyphae or stromata, or solitary, arising through stomatal openings, erect, straight to sinuous or geniculate, simple, (11.5–)14–42.5(–53) × (3.5–)4–5 μm, 0–5-septate, smooth, olivaceous brown to slightly dark brown, paler towards the tips. Conidiogenous loci 2–2.5(–3) μm wide, thickened and darkened. Conidia solitary, narrowly obclavate to subacicular, straight to slightly curved, (16–)23–76.5(–88) × 3.5–4.5 μm, 2–5-septate, olivaceous brown, apex subacute or acute, base truncate to short obconically truncate, 2–2.5(–3.5) μm wide, hila thickened and darkened.
