Ciri dan struktur

Leaf spots subcircular to irregular, pale brown, with dark brown at margin. Pycnidia solitary, scattered on the leaf surface. Pycnidial conidiomata in culture, globose, erumpent, single or clustered in groups of 3–5 pycnidia, coated with hyphae, cream to yellowish translucent conidial droplets exuded from ostioles. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, unbranched, septate, straight, slightly tapering towards the apex, 14.5–25 × 2–3 μm. Alpha conidia hyaline, aseptate, rounded at one end, apex at the other end, usually with two large guttulate, (9.5–)10.5–12 × 3.5–4.5 μm. Beta conidia not observed.

Habitat dan peran ekologis

Cunningham (1931b) and Fletcher (1955a) recorded melanose on living leaves and fruits of citrus. Fletcher (1955b) reported that infection was carried over on dead twigs and branches, where the fungus caused dieback, especially of weakened shoots: he recommended a pre-blossom spray of Bordeaux (3:4:50) for its control. This fungus is also responsible for a stem end rot of fruits held in store.
