This is lichen, which is an organism that is formed by the combination of an algae and a fungus. It will not harm your trees or shrubs--it is simply using them for support. Because they are considered harmless, no control mechanisms are recommended. Physical removal is possible, though that would risk damage to the plants on which they are growing.
