   This rare form presents a thallus arranged in a rosette, brown, brownish, with warts and ridges becoming more or less radiant on the periphery, thallus sometimes fragmented by retraction.

Strongly resembles Wahlenbergiella striatula with which it may be neighboring, but the latter species has a green thallus and simple spores.
