Orceolina

Orceolina is a small genus of lichen-forming fungi in the family Trapeliaceae. Established in 1970 as a replacement name for an earlier genus that was already used for flowering plants, Orceolina comprises just two species that form orange to deep red crusty patches on sun-exposed rocks. These lichens are found exclusively on the windswept subantarctic islands of the southern Indian Ocean, where they grow from sea level to alpine ridges on basaltic and granitic surfaces....read more on Wikipedia.
