Abstract: ["Our results give clear evidence for a faster rate of evolution in two Hypotrachyna clades that includes species occurring in tropical and oceanic habitats in comparison with clades consisting of species occurring in semi-arid and temperate habitats. This suggests that speciation in some lichen clades has proceeded by dispersal into a novel environment, followed by radiation within that environment."
