We can’t see much in your photo because it’s so blurry. But from the general shape and color, we think you may be looking at lichen. If you can send us a clear photo focussed on the area of concern, we’ll do our best to confirm. Here’s what Clemson University says: “A lichen is an unusual organism composed of a fungus and an alga living together in the same body. Lichens often appear as green to gray-green leafy or crusty growths on the trunks or branches of plants. Typically, they occur in abundance on plants that are declining in health or vigor. They are harmless to the plant, and are in no way responsible for the poor health of the plant. Less vigorous plants tend to be more open, increasing sunlight penetration, and subsequent lichen growth.”
