arise as swollen ends of fine filaments which pierce the cuticle, or become erumpent by tearing the cuticle, simple, scattered or gregarious, subhyaline near the base colourless above, up to 140 µm long and about 8 µm wide, composed of a swollen basal cell and a sympodially proliferating, geniculate conidiogenous cell which may develop one or two strengthening septa as it elongates[1]
holoblastic, arising singly from successive sympodial proliferations, fusoid-cylindric, (4-)6(-8)-septate, 60-100 x 13-21 µm with a flat, 6-10 µm wide scar at the base and the apical and subapical cells extended into appendages. The basal and the two terminal cells are subhyaline to pale straw-coloured, and the intermediate cells translucent olive-brown. The apical cell is wholly modified as a filiform, simple or once or twice branched appendage usually about 100 µm long and 3 µm wide. The subapical cell bears one, two, or more usually, three similar but somewhat shorter, simple appendages[1]
On pods and leaves the lesions are circular to very irregular, varying considerably in size, up to l cm or more diameter. They are characteristically zonate and result in dieback and wilt. The seeds are attacked and there is a brown discoloration of the seed coat. On branches and leading shoots the lesions are elongate-oval, up to 2 cm long, with sharply alternating light brown and black zones[2]
