Cercospora phaseoli-lunati

Ciri dan struktur

Leaf spots amphigenous, subcircular to irregularly angular, 2.5–8(–12) mm diam., more or less limited by veins, whitish grey to greyish brown, with a narrow to wide dark brown margin on the adaxial surface, less conspicuous on the abaxial surface. Caespituli amphigenous, mainly epiphyllous, scattered, brown to dark brown. Mycelium internal, indistinct. External hyphae absent. Stromata lacking or formed by few aggregated swollen hyphal cells, immersed in the mesophyll or in substomatal cavities. Conidiophores in small, loose fascicles of up to 6, arising from internal hyphae of small hyphal aggregations, breaking through the adaxial epidermis of the leaves or penetrating through stomatal openings, or solitarily arising through stomatal openings, erect, rarely branched, straight to geniculate or subcylindrical to mostly attenuated towards the tips, conical or irregularly shaped, (18–)21.5–94(–102) × (3.5–)4–5 μm, 1–6-septate, smooth, brown to dark brown. Conidiogenous cells terminal, monoblastic or polyblastic; loci distinct, up to 2.5 μm wide, thickened and darkened. Conidia solitary, narrowly obclavate to subacicular, straight to curved, (16–)19–94(–105.5) × 2.5–3.5 μm, 2–7-septate, hyaline to subhyaline, smooth, apex subacute or acute, base truncate to short obconically truncate, up 2.5 μm wide, hila thickened and darkened.
