Mossy Growth on Crepe Myrtles

A large number of our crepe myrtle trees have a mossy growth on them, which is similar to that which grows on oak trees. It is a somewhat scalely green/gray colored growth. It looks similar to that mossy growth that appears on rocks and some small patches of bare ground occasionally. It has increased in amount and the number of trees that it is growing. Is it harmful? How can we rid our trees of this growth?

It is lichen, which is harmless to the tree. Here is more information: https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm ^[1]
