Usnea Lichens
Where in the World?
Lichens can be found almost everywhere on Earth except where their habitat has been eliminated or degraded by pollution, as in the centres of big cities. They grow in all seasons, although they are abundant only where the environment is most pure and unspoiled.
Most species of Usnea like sunny spots with some humidity, forming bushy or pendant tufts on trees or shrubs, although a few species grow on rocks.
