|I live in the Wilmington, NC area and the live oak trees have a light green crusty material on the branches. I think it is a fungus as the trees with the fungus seemed to be dying. Am I right and what can be done to get rid of the fungus?

|It's probably lichen that's growing on the trees. Although its living off of the trees, it causes no harm to them and should be enjoyed for the texture it adds! In short, it's not anything to really worry about. But if you don't like it you can spray it with lime/sulfur this winter when the trees are dormant. The lime sulfur will kill it and it will slough off on its own. Don't use lime sulfur now - it will burn the leaves of your trees.
