Pseudocercospora bradburyae

Ciri dan struktur

Leaf spots amphigenous, subcircular to irregularly angular, (2.5–)4–8.5 mm diam., limited by veins, reddish brown to brown, with indefinite margins. Caespituli mainly epiphyllous, olivaceous brown to slightly dark brown. Mycelium internal and external. External hyphae branched, 2.5–3.5 μm wide, septate, olivaceous brown to brown, smooth. Stromata lacking or small, about 10–18 μm diam., immersed in the mesophyll or in substomatal chambers. Conidiophores often in small, loose to slightly dense fascicles of up to approx. 10 conidiophores, arising from stromata or breaking through the adaxial epidermis of the leaves, occasionally solitary arising from external hyphae, straight to sinuous or somewhat geniculate, rarely branched, (11–)13–44(–48.5) × (3.5–)4–5 μm, 0–3(–4)-septate, smooth, olivaceous brown to brown, paler towards the tips. Conidiogenous cells terminal, 10–15 μm long; loci inconspicuous to distinctly denticle-like, not thickened and not darkened, 1.5–3 μm wide. Conidia solitary, narrowly obclavate to subacicular, straight to curved, (30–)38–110(–130) × (2.5–)3–4(–4.5) μm, 3–9-septate, olivaceous brown, smooth, apex subacute to rounded and slightly narrower, base truncate to obconically truncate, 1.5–3 μm wide, hila not thickened and not darkened, occasionally somewhat refractive.
