Antoniomyces is characterized by solitary to gregarious, superficial, black, circular, ascostromata opening by longitudinal slits and forming in the central area of mycelium, clavate to subglobose asci and cylindric-ellipsoidal or ellipsoidal to narrowly ovoid, 1-septate ascospores (Inácio et al. 2012).
