tree coverings and rot

Asked September 29, 2020, 2:27 PM EDT

I have attached pics of a fallen branch and trunk for a silver maple. Can you tell me what the covering is on the branch and the covering on the trunk? Is there anything I can/should do for this tree? The green stuff on the tree is only on N side. Thanks!!

The white are lichens and the photo isn’t clear enough to be positive but the green is probably moss and lichens. They don’t hurt the tree and grow where there is moisture and shade.
