White spots on Maple tree and Lilac trunks

Asked July 13, 2020, 4:54 PM EDT

I have noticed white spots on our Crimson King Maple and Lilac shrub. We lost a Sugar ? Maple a few years back that had this. The lilac is not looking good, I trimmed it. Any ideas? Thanks!!!

Hello. Happy to help.

They appear to be form of lichen. No need to worry about it.
