The photos above show examples of two of the many colorful lichens found in the high peaks of Pinnacles National Park in California. Lichens are organisms made up primarily of a fungus and either a green or a blue/green alga. The fungus and alga have a symbiotic relationship with one another, though the fungus is the dominant partner. Algae photosynthesize, feeding the fungus; whereas the fungus absorbs water and other nutrients, thus benefiting the algae. Photo taken on the High Peaks Loop Trail on November 25, 2016.
