The foliose and umbilical thallus (attached by a single central crampon, the umbilicus), 3-6 (15) cm in diameter, is gray-brown to blackish-brown in dry weather, olive-green when it rained. Its upper surface is covered with convex pustules and bunches of brown-black coral isidia, the central part being covered with a white bloom. The pustules corresponding to propagules: the migration of these pustules from the center to the periphery gives rise to marginal isidies which ensure the vegetative reproduction of the thallus.
