Colony fully covers the Petri plate (90 mm) by the third day at 25 and 30 °C but does not reach the lid of the plate. At 20 °C, colony reaches a diameter of 70.5 mm after 3 days. Vertical growth is lower at 25 and 30 °C than at 20 °C. The colony does not reach the lid after 3 days. At 30 °C, sporulation is excellent, with branching of sporangiophore more frequent than in others. Monopodial branching more prominent but sympodial and dichotomous branches also observed. On PDA, cultures are white and pale brown in the middle with grey to pale brown sporangia. Colony reaching 64 mm diameter after 3 days of incubation at 25 °C. Optimal growth and excellent sporulation were observed on both MEA and PDA media at 30 °C. At 37 and 8 °C in MEA, growth is observed but with no sporulation. The colony reaches a diameter of 31 mm at 37 °C after 3 days. At 8 °C, the colony reaches a diameter of 14 mm after 9 days. Growth is observed at temperatures ranging from 8 to 37 °C.</paragraph>
