Notes – Döbbeler (1978) introduced Bryosphaeria in Dothideomycetes, genera incertae sedis by transferring Leptosphaeria cinclidoti (current name Bryosphaeria cinclidoti) which was placed in Leptosphaeriaceae. Bryosphaeria is characterized by globose or subglobose ascomata, with the surface being covered by brown, branched setae, bitunicate, fissitunicate asci and hyaline to dark brown, fusiform, 1–5-septate ascospores (Döbbeler 1978, Li et al. 2014). Bryosphaeria best fits Trematosphaeriaceae in having bitunicate, cylindric-clavate asci, a peridium with thick-walled cells of textura angularis, with dark brown outer layers and hyaline inner layers, and hyaline to dark brown, fusiform ascospores, but differs in septation of the ascospores (1–5-septate in Bryosphaeria versus 3-septate in Trematosphaeria) and surface and papillae of the ascomata (setose, rarely with visible papillae in Bryosphaeria versus glabrous and with a short papillae in Trematosphaeria). Hence, based on these similar morphologies, Li et al. (2014) placed Bryosphaeria in Trematosphaeriaceae. Sequence data are not available for Bryosphaeria species and fresh material for sequencing is necessary to establish the taxonomical position of this genus.
