Q.Azalea and Ash Tree: lichen or fungus?

Zone 08807 | Tea added on November 29, 2017 | Answered

My azaleas are suffering with what appears to be lichen. I have tried cutting off the affected branches but more are affected. The adjacent ash tree also has branches affected similarly but still sprouts leaves. Please advise me what to do. Photo attached.
