Young colonies on PCA are loosely lanose to arachnoid. Sporulation on the PCA substrate surface is in large loose clumps of branching chains of conidia. These clumps are concentrated in the central 1 cm diam of the surface colony. Otherwise the colony is composed of abundant but uncrowded, ascending, simple and funiculose hyphae that form an aerial conidiogenous layer. Aerial hyphae bear scattered lateral branches and numerous apical branches that produce tufts of sporulation in the wooly aerial layer.
