Type species: Dothiopeltis arunci E. Müll., Sydowia 10(1–6): 198 (1957) .
Notes: Dothiopeltis arunci was collected from Aruncus silvester in Switzerland. The genus is epiphytic on dry stems. Ascomata are superficial, rounded, lenticular, scattered to clustered, shiny, lacking ostioles, forming brown, septate, vegetative hyphal webs at the margin, immersed in host tissue and lack paraphyses. The upper wall of the peridium is composed of thickened, dark, radially globose or angular cells, with well-developed basal walls. Asci are 8-spored, bitunicate, ellipsoidal to clavate, sessile to subsessile and ascospores are hyaline, muriform, ellipsoidal to cylindrical and occasionally clavate to obclavate (Müller 1956). Holm and Holm (1977) found that D. arunci has longitudinal slit-like openings and they did not see the basal layers of the peridium. The second species, D. cicerbitae Granmo & Math. was found on stalks of Cicerbita alpina in Norway and is distinct from D. arunci in several aspects (Granmo and Mathiassen 2013). The asexual morph of Dothiopeltis was reported as hyphomycetous, idriella-like which is characterized by hyaline or brown hyphae, brown, simple, aseptate geniculate conidiophores, tapering towards the tip and lunate or falcate conidia with acuminate tips, produced in dry heads (Nelson and Wilhelm 1956; Hyde et al. 2013; Wijayawardene et al. 2017b).
