Colonies on oatmeal agar at 20 °C attaining a diameter of 2-3 mm in 14 days, at first smooth, soon becoming powdery, pale buff to brown; reverse pale brown; exudate and odour absent. Vegetative hyphae smooth, thin-walled, hyaline or nearly so, 1.5-2.5 µm wide. Fertile hyphae usually slightly wider, often ascending, profusely branched in apical region, thus occasionally becoming synnema-like. Conidiogenous cells arising from undifferentiated or slightly thick-walled hyphae, pale brown near base, hyaline towards apex, variable in shape and size, usually about 2-2.5 wide at base and 10-20 µm long, cylindrical, tapering towards tip, forming conidia by sympodial growth on conspicuous denticles about 1 fim. long, occurring scattered in apical region of cell. Conidia smooth, thin-walled, hyaline, guttuliform to ellipsoidal, 2.5-3.5 × 1.6-2.2 µm, with pointed base, occasionally becoming inflated and giving rise to some globose to ellipsoidal secondary conidia or a short secondary conidiophore.
