Description: Sexual morph: Stromata pulvinate, with a wide base, sometimes cylindrical and extending towards base, generally hard, pale yellow, pale orange, brownish orange, brownish yellow, brown, or greyish yellow, no hypothallus, stroma surface generally smooth or slightly pruinose, opaque or glossy; generally KOH+; stroma tissue of compact textura intricata. Perithecia completely embedded in stroma, scattered, subglobose. Asci mostly cylindrical to clavate, with caps 1–3 µm. Ascospores hyaline, multi-septate, smooth, long fusiform to filiform. Asexual morph: Conidiomata as simple depressions of stroma surface, shallow or deep, U-shaped, from top view elongated and generally fusing with neighboring conidiomata, sometimes arranged in a circular fashion, conidiophores in a compact palisade, short, monoverticillate with 2–5 phialides per verticil, once monochasial, sometimes twice monochasial; phialides cylindrical, long and slender, tapering towards apices.
