They settled mountains as the first...
Lichens, fungi and algae are sometimes almost invisible. There, where we can not go, they have an easy access. They inhabit various habitats. On stones in streams, on rocks exposed to sun, on lava flows, on a tree bark and twigs - their colours are grey, but most often very spectacular. They are very stable components of the mountains.
