Lichens may superficially look like mosses, and have common names that include the word "moss". Lichens can grow on almost any surface. They grow abundantly on bark, leaves, mosses, rock and on other lichens, and can be found growing in rain forests alpine regions and in temperate woodland. Oakmoss grows primarily on the trunk and branches of oak trees, but is also commonly found on the bark of other deciduous trees and conifers
