Fungi causing ringworm infections produce septate (segmented) hyphae. The germ tubes then grow into hyaline septate hyphae. Typically seen is brown septate branching hyphae or dark brown budding cells. Hyphae in this form are septate and hyaline. "E. floccosum" has septate, hyaline hyphae. Pseudoparaphyses are filiform, hyaline, septate, and branched. The cap cuticle is composed of interwoven septate hyphae, which are often finely incrusted. It has septate hyphae with a woolly colony texture and white mycelia. Hyphae can be either septate or coenocytic. In addition, the hyphae of the mycelium are septate and hyaline. The pileipellis is a trichodermium of interwoven septate hyphae, with long cylindrical cells. Hyphae are brown, cylindrical, and septate and are composed of thick-walled cells. Dermatophytes known to cause athlete's foot will demonstrate multiple septate branching hyphae on microscopy. In nature, "P. digitatum" adopts a filamentous vegetative growth form, producing narrow, septate hyphae. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei.
