Description: Thallus crustose, episubstratic, grey, often granular-warty, thin, continuous. Apothecia immersed in 1.5-2 mm wide, soralia-like thalline warts, 1(-3) per wart, with a widely open, black, but densely and coarsely white-pruinose disc, and an often lacerate, sometimes sorediate thalline margin.
