Mycelium internum ad externum, pallidum-brunneum ad brunneum; hyphae superficiales septatae, leves, ramosae, 2.5-4.5 µm latae. Stromata absunt. Conidiophora sola vel in fasciculis laxis usque ad sex, orientia ex hyphis superficialibus, lateralia, erecta, ampulliformia ad subcylindracea, recta vel interdum geniculata, 8-45 x 3.0-4.5 µm, raro ramosa. Cellulae conidiogenae terminales, pallidae-brunneae et pallidiores in apice. Conidia sola, pallida-brunnea, subcylindracea, 10-47 x 2.5-3.5 µm, recta vel partim curvata, apex rotundatus, basis obconice truncata ad subtruncata, 0-5 septata, interdum constricta in uno vel pluribus septis, levis. Original description Leaf spots amphigenous; conspicuous on abaxial surface, polyangular to irregular, often vein-limited, 2-8 mm wide, margins diffuse or narrowly water-soaked, dark brown in centre becoming paler towards margin, often widespread over the entire leaf surface, lesions sometimes covered with abundant sporulation; inconspicuous on adaxial leaf surface, irregular, margins diffuse, pale to yellowish brown, always smaller than the corresponding lesion on the abaxial surface. Mycelium internal and external, pale to medium brown; superficial hyphae septate, smooth, branched, 2.5-4.5 µm wide. Stromata absent. Conidiophores solitary or in loose fascicles of up to 6, arising from superficial hyhphae, lateral, erect, ampulliform to subcylindrical, straight or occasionally geniculate, 8-45 x 3.0-4.5 µm, rarely branched. Conidiogenous cells terminal, pale brown becoming paler towards the apex, proliferating percurrently or occasionally sympodially, smooth or minutely roughened from torn annulations, rounded at apex. Conidia solitary, pale brown, subcylindrical, 10-47 x 2.5-3.5 µm, straight or partially curved, apex rounded, base obconically truncate to subtruncate, 0-5 septate, sometimes constricted at one or more septa, smooth; hila inconspicuous. Cultural characteristics: Colonies on malt extract agar (Difco) circular, up to 30 mm diam. after 28 days at 25 °C, grey to pale olivaceous-grey, reverse olivaceous black, radially furrowed, flat and raised in the centre, margin entire, smooth. Etymology Derived from the name of the host plant Mangifera in the Anacardiaceae.
