    The moss like substance is most likely lichen. It is probably not what is causing the trees to fail, but is rather a symptom that the tree is ill as they do like to attach to trees that are unhealthy. Besides lost leaves, do the trees have any other signs of being ill so that we can try to identify it for you?

    Both kinds of damage sound like Japanese beetles. But occasionally, believe it or not, slugs also cause this kind of damage on tree leaves. If you are not seeing the pest, check the leaves at night for slugs.
