Dictyodothis was established to accommodate two species, D. berberidis and D. excavata in Dothideaceae. von Arx & Müller (1975) placed Dictyodothis in Pleosporaceae according to morphological character such as “paraphysoids” in the locules. However, Barr (1981) reported “paraphysoids” are the walls and remaining cytoplasmic strands of discharged asci and ascospores which are similar to D. sambuci (Thambugala et al. 2014a). Therefore, Dictyodothis was placed in Dothideaceae by Barr (1981). The sexual morph of this genus is characterized by black, coriaceous and multiloculate ascostromata which are discoid to pulvinate. The cells of the ascomata wall are composed of dark brown to black cells of textura prismatica and textura angularis. Locules are ostiolate and asci contain 1–2-seriate, yellowish brown to dark brown, muriform ascospores. Asexual morphs have not been reported for Dictyodothis (Thambugala et al. 2014a).
