[1] The basic structure of crustose lichens consists of a cortex layer, an algal layer ...
Tillandsia bourgaei growing on an oak tree in Mexico. An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it.

Oakmoss (scientific name Evernia prunastri) is a species of lichen.It can be found in many mountainous temperate forests throughout the Northern Hemisphere.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 such as fir and pine.
It prefers living on the twigs and branches, of trees, than on the trunks. On average, this species took up 3.1 kg of dry weight on the branches of trees, and 7.1 kg of dry weight on the twigs of trees. If there is an assumed 12.5 kg of biomass per tree, and there are 40 mature trees per hectare, there are about 500 kg/ha of dry weight.
