Based on phylogenies of LSU and SSU analyses and morphological studies, Chu et al. (2015) established Ebullia to accommodate the type species Ebullia octonae (=Nimbospora octonae). Ebullia octonae differ from Nimbospora effusa and N. bipolaris by their thick peridium, and ascospores that lack equatorial tufts of appendages but possess polar and equatorial subulate appendages after the sheath is dissolved (Chu et al. 2015). Ebullia is characterized by subglobose to ampulliform ascomata, immersed, ostiolate, with long necks, periphysate, eight-spored asci, clavate, ellipsoidal ascospores, hyaline, one-septate, not or slightly constricted at the septum, with a gelatinous sheath and one similar appendage at each end, swells in water (Chu et al. 2015). No other species have been introduced to Ebullia, which remains monotypic.

Type species: Ebullia octonae (Kohlm.) K.L. Pang

Other accepted species: This genus is monotypic.
