Description
Brittle lichen is a lichen genus found in cold regions, often growing on rocks or tree bark. It forms small, dark-colored, bush-like structures with thin, branching lobes. Some species in this group can withstand extreme cold and are found in Arctic and Antarctic environments. Brittle lichen lichens play a role in nitrogen fixation in their ecosystems.
