Maple Tree leaf spots

Hi, hope someone can help. I we have young maple tree (October glory) that has spots on all leafs . is this a fungus or any type disease? should I be concern about it?
Tree is in Maryland. I noticed some spots last fall but now in spring it seems like spots are everywhere.

I have similar tar spots here in Maine where maple trees are abundant in the wild thus treating mine will not eliminate the problem as the fungus is transported by the wind.

Search "maple tree tar spots" for a reference. Although the spot they show seems to match mine, mine don't seem to go through the yellow/green stage, just show up as black spots and increase in number and size.

From reading years ago best i can do is clean up the old leaves each fall, helps a little but 10' away are woods full of more trees and infected leaves.

Note, even after some terrible years my trees are doing fine.
