top one is Honey Locust, apparently the thornless variety that is common as a shade tree. The other one Look like Ash.
I'm not sure if it a fungus or mold or scale or blight or whatever but that would exactly describe what I have seen.I thought maple too for the top pic. Didn't know it was a fungus, but yeah these maples are completely black in some places, in other areas the black looks like it's been lightly spray-painted on.
