<paragraph pageId="0" pageNumber="57">Day-old cultures are white, cottony, floccose, have erect sporangiophores with hyphae reaching the lid of the Petri plate in MEA. The white color of the colony persists even after 6 days. At maturity, the colony reverse is white or pale yellow. On MEA at 25 °C, the colony reaches a diameter of 51 mm after 3 days of incubation. At 20 and 30 °C, the colony reaches a diameter of 47 mm and 44.5 mm respectively after 3 days. Sporulation is excellent at 20 to 30 °C. At 30 °C, mostly unbranched sporangiophores are observed with few sympodial branches. On PDA at 25 °C, colony reaches a diameter of 48 mm after 3 days of incubation. The front and reverse of the colony are white in both MEA and PDA. Growth is observed at temperatures ranging from 8 to 30 °C. Optimal growth and excellent sporulation were observed at 25 °C on both MEA and PDA media. No growth was observed at 37 °C. At 8 °C in MEA, the colony reached a diameter of 34 mm after 9 days but with no sporulation.</paragraph>
