Colonies on potato dextrose agar showing an average growth (mm/d) of 9.2 (± 0.3) at 20 C, 13.9 (± 0.4) at 25 C, 13.0 (± 0.5) at 30 C and 7.1 (± 0.4) at 35 C); colony margin entire, aerial mycelium white orange, lanose. Pigmentation in reverse pale orange to orange-gray center. Sporulation starting early in aerial mycelium in false heads. Sporodochia produced after 2 wk. Conidiophores in aerial mycelium erect or prostrate, conidiophore identical with phialides. Phialides of aerial mycelium monophialidic, doliform. Conidia from aerial mycelium, thick-walled, 3-4-septate, 32.0 µm (± 0.8 µm). Macroconidia from sporodochia thick-walled dorsal side more curved, 36.2-37.4 µm (± 1.0 µm). Apical cells blunt, foot cell foot-shaped. Microconidia absent. Chlamydospores appearing single but more frequently in intercalary chains in aerial mycelium.
