Pathogenic on host. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, pale brown to brown, solitary, setose, globose, ostiolate. Pycnidial wall of textura angularis. Conidiogenous cells phialidic, ampulliform or lageniform. Conidia aseptate, hyaline, smooth- and thin-walled, allantoid or ellipsoidal (adapted from Valenzuela-Lopez et al. 2018).

Notes: Vacuiphoma is characterised by pycnidial, brown to dark brown, solitary, glabrous, subglobose or obpyriform, non-papillate conidiomata, and a pycnidial wall of textura angularis. Vacuiphoma is unique and was named based on the existence of empty pycnidial structures. Vacuiphoma is phylogenetically a distinct genus in Didymellaceae. Molecular markers available for Vacuiphoma are ITS, LSU, BTUB and RPB2.
