"Acremonium strictum" grows readily at 30 °C on glucose peptone agar, showing mycelium of approximately 50mm in size in 7 days. Colonies are flat, with smooth, wet, velvety or floccose texture, sometimes resembling thin cottony mounds. The colour of mycelia ranges widely from light pink to orange, and sometimes yellow, white or green. "A. strictum" filaments are sometimes bound together into ropes several cells in diameter. Conidia grow as wet clusters or dry chains, and grains produced are white to pale-yellow, soft and variable in shape. Subcultures of the fungus can also be grow within seven days into smooth, moist, pink mycelia that resemble thin cotton.
