The image shows the cottony thallus surface of a lichen called Cryptothecia striata growing on the bark of a tree.
A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi in a mutualistic relationship. The lichens are very slow-growing organisms and they can live for hundreds or thousands of years, depending on their species.
In this image, you see the thallus (the body) of Cryptothecia striata which is covered with cottony white structures. There are many cracks in the bark that the lichen has invaded.
