Lichen

Lichen on Birch, near Fairbanks, Alaska
According to the USDA Forest Service:
Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies. The alga can be either a green alga or a blue-green alga, otherwise known as cyanobacteria. Many lichens will have both types of algae.
Preserved and found in the desert of Namibia along the coast line
