Today, the Wikipedia can say it better than me:
Lichens ( /ˈlaɪkən/,[1] sometimes /ˈlɪtʃən/)[2] are composite organisms consisting of a symbiotic organism composed of a fungus (the mycobiont) with a photosynthetic partner (the photobiont or phycobiont), usually either a green alga (commonly Trebouxia) or cyanobacterium (commonly Nostoc).[3] The morphology, physiology and biochemistry of lichens are very different from those of the isolated fungus and alga in culture. Lichens occur in some of the most extreme environments on Earth—arctic tundra, hot deserts, rocky coasts, and toxic slag heaps.Lichens are so incredible, oftentimes there are no words. They are everywhere, living hundreds, perhaps thousands of years, breaking down mountains, quietly transforming our world...
Ancient spirits.
In silence, they tend the desert.
Trust in them to know what is best.
