Dothideopsella Höhn., Sber. Akad. Wiss. Wien, Math.- naturw. Kl., Abt. 1 124: 70 (1915)
Saprobic on dead wood and stems in terrestrial habitats. Sexual state: Ascomata scattered, gregarious, immersed to semi-immersed, or erumpent, nearly superficial, globose, uniloculate, subglobose or obypyriform, glabrous, dark brown to black, ostiole central, broadly or narrowly conical, with a dark brown to black papilla. Peridium thin to thick, of unequal thickness, slightly thick at the basal ascoma, composed of dark brown to black, thin-walled, pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, filamentous, distinctly septate, cellular pseudoparaphyses, anastomosing without a gelatinous coating. Asci 8-spored, bitunicate, fissitunicate, cylindrical to oblong, with a knob like pedicel, apically rounded with welldeveloped ocular chamber Ascospores phragmosporous, ellipsoidal to fusiform, brown or yellowish brown, septate, slightly constricted at the septum, smooth-walled. Asexual state: Unknown (from Ariyawansa et al. 2013).
Type species: Dothideopsella agminalis (Sacc. & Morthier) Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 124: 70 (1915)
Phylogenetic study: None
Notes: Dothideopsella was introduced by Höhnel (1915) and is typified by Dothideopsella agminalis (Sacc. &
Morthier) Höhn. The genus was established to accommodate Dothideomycetes species characterized by a broad peridium structure, with conical , papillate ostioles, and phragmosporous, brown ascospores (Ahn and Shearer 1998; Ariyawansa et al. 2013). Lumbsch and Huhndorf (2010) treated Dothideopsella in Dothideomycetes, genera incertae sedis, while Index Fungorum (2014) lists the genus in Leptosphaeriaceae. Ariyawansa et al. (2013) tentatively placed Dothideopsella in Phaeosphaeriaceae based on its morphological characters which are typical of Chaetoplea. Dothideopsella however differs from Chaetoplea in having a peridium composed of pseudoparenchymatous cells,while the peridium in Chaetoplea is composed o f scleroplectenchymatous cells. The placement of the genus in Phaeosphaeriaceae was supported by Wijayawardene et al. (2014b). Thus we tentatively place Dothideopsella in Phaeosphaeriaceae until molecular date proves otherwise.
