Colonies superficial, black, scattered, mostly circular, elliptical or variable in shape on the leaf surfaces. External hyphae brown, septate, sinuous, smooth, without appressoria. Internal stroma composed of hyaline to pale, branched, sinuous, smooth hyphae. Sexual morph: Ascomata superficial, elongate, often confluent, dark-brown to black, initially irregular, becoming elliptical to boat-shaped. Upper wall composed of dark, irregular cells of textura prismatica. Hamathecium composed of filiform, hyaline, septate, branched, sometimes with brown to dark brown pseudoparaphyses with smooth to slightly verrucose tips, swollen in gelatinous matrix. Asci bitunicate, 6–8-spored, cylindric-clavate to clavate, 1–2 or multi-seriate, not stained in IKI, thick-walled. Ascospores cylindricellipsoidal or ellipsoidal to narrowly ovoid, 1-septum, initially hyaline becoming light-brown to brown, verrucose with the mucilaginous sheath at maturity. Asexual morph: Pycnidia blackish appearing as swats scattered among the ascomata. Pycnidiospores cylindrical, hyaline, smooth-walled (Inacio et al. 2012).
Notes: The monotypic genus Antoniomyces was intro- duced by Inacio et al. (2012). Antoniomyces is character- ized by solitary to gregarious, superficial, black, circular, ascomata 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-septum ascospores (Inacio et al. 2012).
