Organism of the group Lichenes, which
consists of a fungus and an alga existing in
a mutually beneficial relationship. Found on
trees, rocks, and other substrates, lichen
flourishes under very adverse conditions.
Some lichens have food value, for example
reindeer moss and Iceland moss; others give
dyes such as litmus, or are used in medicine.
They are sensitive to atmospheric pollution
(see indicator species).
