Summary Author: Cindy Todd; Jim Foster
The photo above shows multicolored lichen attached to a rock face in Pinnacles National Monument, California. Lichens are primitive organisms that are able to withstand very large fluctuations in temperature and moisture. If need be, however, they'll go into a state of dormancy in order to endure the most extreme weather conditions. The examples shown here are crustose lichens. They grow tightly appressed and attach themselves to rocks, trees or even building surfaces and attempted removal will usually damage the surface of the substrate they're growing upon.
