Went for a hike in the woods,
just before the heavy rains
were due to come through.
Lots of lichen on trees and rocks.
So colorful, and definitely
In Missouri, the most common forms
are "speckled shield" and "green shield"
Lichens have no chlorophyll,
and are incapable of photosynthesis,
but they absorb nutrition from organic matter,
and are not harmful to trees.
There are an estimated 17,000 varieties
world wide, and make up a substantial part
of the diet in the Arctic.
