Thallus: evanescent, granulose to verrucose, mostly covered with apothecia, grey brown to dark brown. Prothallus absent or present, brown to black. Apothecia lecanorine, 0.3-0.6 mm diam., abundant, crowded, often contiguous, constricted at base to broadly attached, margin prominent, sometimes crenulate. Hymenium 60-80 µm tall.
