Description: Thallus crustose, mostly endosubstratic, continuous to faintly rimose, grey to greenish grey, covered with fruiting warts. Apothecia lecanorine, immersed in 0.2-1.2 mm wide thalline warts, 1(-2) per wart, with an expanded, regularly rounded, black but usually grey-pruinose, 0.3-0.8 mm wide disc and a thin, smooth thalline margin. Epithecium yellowish to dark brown, K+ violet; hymenium colourless; paraphyses lax, branched and anastomosing; hypothecium yellowish.
