Saprobic on dead woody bark. Sexual morph: Pseudostroma immersed, becoming erumpent; ectostroma pale brown to grey, containing periphyses; ostioles cylindrical. Perithecia globose to lenticular, dark brown, wall of cells of textura angularis. Paraphyses septate, unbranched, hypha- like. Asci 8-spored, ellipsoid to fusoid, without a refractive canal at apex. Ascospores brown, ellipsoid-fusoid, 1-euseptate, with gelatinous appendage at each truncate end. Asexual morph: Coelomycetous. Conidiomata pycnidial, multilocular, forming a long neck. Paraphyses hyaline, cylindrical, septate, unbranched, hypha-like. Conidiophores subcylindrical, hyaline to pale brown, septate, unbranched. Conidiogenous cells cylindrical, hyaline to pale brown, proliferating percurrently at apex.

Type genusPhaeoappendicospora Senan., Q.R. Li & K.D. Hyde

Notes – Phaeoappendicosporaceae was introduced by Crous et al. (2019b) based on Phaeoappendicospora as the type genus and Neophaeoappendicospora as the second genus. Both genera have similar characters, but Neophaeoappendicospora is distinct from Phaeoappendicospora by its larger ascospores and presence of asexual morph.
