Mycosphaerella cruenta

Ciri dan struktur

Leaf spots amphigenous, subcircular to irregularly angular, (2.5–)4–8.5 mm diam., limited by veins, reddish brown to dark brown, with an indefinite margin. Caespituli amphigenous, denser, darker olivaceous to almost sooty on the abaxial surface of the leaves than on the adaxial side. Mycelium internal and external. External hyphae branched, 2.5–3.5 μm wide, septate, olivaceous brown to brown, smooth. Stromata lacking or small, 8–14 μm diam., immersed in the mesophyll or in substomatal cavities, subcircular to irregular, brown to dark brown. Conidiophores in small, loose, moderately large and dense fascicles formed by up to approx. 10 conidiophores, arising from stromata, breaking through the adaxial epidermis of the leaves or penetrating through stomatal openings, sometimes solitary, arising from external hyphae, straight to sinuous or somewhat geniculate, rarely branched, (12–)15.5–54(–58.5) × (3.5–)4–5 μm [in YMM125 up to 120 µm long], 1–3-septate, smooth, olivaceous brown to brown, paler towards the tips. Conidiogenous cells terminal or subterminal, a conidiophore can be reduced to a single conidiogenous cell; loci 2–2.5 μm wide, not thickened and not darkened. Conidia solitary, narrowly obclavate to subacicular, straight to curved, (30.5–)42–132(–154) × (3–)3.5–4.5(–5) μm, 2–10-septate, olivaceous brown, smooth, apex subacute to rounded and slightly narrower than the rest of the conidiophore, up to 2.5 μm wide, base truncate to obconically truncate, 2–2.5(–3) μm wide, hila not thickened and not darkened.
