Colonies are flat, smooth, moist, pink to orange, with regular and sharp margin; reverse pink. Hyphae are narrow, hyaline, producing conidia laterally from small collarettes directly on the hyphae, or from lateral cells which are sometimes arranged in dense groups; lateral cells flask-shaped or nearly cylindrical. Collarettes are unpigmented, about 1.5 µm wide. Conidia are hyaline, smooth and thin walled, broadly ellipsoidal to cylindrical or allantoid, 3.0-3.5 x 1.5-2.5 µm, produced in slimy heads. RG-1 organism.
