Colonies on the adaxial leaf surface. Mycelium superficial and immersed, pale, branched and anastomosing, smooth or verruculose, septate,1.5-3 µm thick. Stroma absent. Conidiophores arising terminally and laterally on the hyphae, macronematous, single, composed of a mononematous stipe and a head of branches bearing conidia, sometimes unbranched. Stipes erect, straight or flexuous, smooth, septate, brown, paler towards the apex, up to 250 µm long x 3-5.5 µm thick at base tapering to 2.5-3.5 µm thick at the apex. Primary branches sometimes bearing branchlets, pale brown, flexuous, up to 100 µm long, usually 15-30 µm long x 1.5-3 µm thick. Conidiogenous cells polyblastic, integrated, terminal, sympodial, conidial scars c. 0.5 µm wide. Conidia solitary, acropleurogenous, pale, verruculose, nonseptate, ellipsoidal to obovoid, apex obtuse, base truncate, (3-) 4.5-6 (-7) x (1.5-) 2-3 µm; hilum c. 0.5 µm thick.

Sporulation is usually associated with an indistinct reddish-brown leaf speckle.
