Epidermophyton floccosum produces smooth, club-shaped macroconidia with rounded ends that are arranged singly or in clusters. Each contains 2-6 cells, separated by transverse septae. Microconidia are never produced.
The top image to the right shows an E. floccosum culture demonstrating colonies that are slow-growing, greenish-brown, or khaki-colored with a suede-like surface. The bottom right image shows an E. floccosum lactophenol cotton blue slide demonstrating septate hyphae, and smooth, thin-walled, club-shaped, multicellular macroconidia.
