Sexual morph: Ascostromata relatively large, superficial, circular or cupulate, slightly raised, pedicellate, solitary, exterior surrounded by brown mycelium, orange to red-brown at the margin or edge, dark brown to black in the centre, cells of ascostromata comprising a maze-like arrangement of mixed, brown-walled cells of textura angularis to subglobosa or epidermoidea, multi-loculate. Locules in a single layer at the periphery of the ascostromata, subcylindric-elongate, obpyriform to ovoid, crowded, opening by small, narrow, vertical ostiole. Hamathecium comprising numerous filiform, branched, septate, cellular pseudoparaphyses, embedded in a gelatinous matrix. Asci 8-spored, bitunicate, fissitunicate, narrowly cylindric-clavate, pedicellate, apically rounded with a small ocular chamber.

Notes: Ascoporiaceae is presently treated in Dothideomycetes as family incertae sedis (Wijayawardene et al. 2018). The family is monotypic with a single species Ascoporia lateritia (Hyde et al. 2013). Ascoporiaceae lacks molecular data to establish phylogenetic placement.
