Lichen on olive tree

Question

We have 2 camellias and an olive tree that have what appears to be lichen. It started as green fuzzy stuff on the branches and has progressed to scaly patches on the trunks and limbs. We used MossMax recommended by our local garden center with no results. Can you help?
