|Crape myrtles typically have flaking bark so that check to make sure there's actually something growing on the bark rather than the bark just naturally shedding. Sometimes lichen grows on the branches but it doesn't hurt the bark or the branches so it's nothing to be worried about. If it annoys you, spray the tree during the dormant season with a lime-sulfur (Bordeaux) product. This will kill the lichen which will eventually weather away. Other fungal diseases, such as powdery mildew, can be treated with a copper based fungicide. Be sure to apply according to label directions. Best wishes with your crape myrtle.
