The ultrastructure of different fungi have been described in recent literature; however, few reports have concerned dermatophytes.
Fine structure of Trichophyton violaceum was observed using electron microscopy.
Hyphae appeared as branched segmented filaments with a cell wall consisting of two layers. Thin electron dense plasma membrane was evident continuous with the inner surface of the cell wall. Septal walls with central pores and a uniform electron opacity plugs were seen. The hyphae were multinucleated and the cytoplasm contained endoplasmic reticulum, mitochondria, and vacuoles.
Although these findings showed ultrastructural similarities of the cell wall with Microsporum canis, Microsporum gypseum and Microsporum audouinii, there were some points of difference in the ultrastructure of the hyphae in Epidermophyton floccosum, and in the mitochondria of Trichophyton mentagrophytes as described by other investigators.
近期文献中已描述了不同真菌的超微结构；然而，涉及皮肤癣菌的报道较少。
使用电子显微镜观察紫色毛癣菌的精细结构。
菌丝呈分支的节段状细丝，细胞壁由两层组成。薄的电子致密质膜明显与细胞壁内表面连续。可见带有中央孔和均匀电子不透明栓的隔膜。菌丝多核，细胞质中含有内质网、线粒体和液泡。
尽管这些发现表明细胞壁的超微结构与犬小孢子菌、石膏样小孢子菌和奥杜盎小孢子菌相似，但絮状表皮癣菌菌丝的超微结构以及其他研究者所描述的须癣毛癣菌线粒体的超微结构存在一些差异。
