Attached are photos of a Black Oak tree in our yard. The first two photos show an area with a substance weeping out of the tree. The black area is a tree kote that I sprayed on the area. The substance seeped through the coating after I applied it. Can you tell me what this is and if it can be treated? The third photo shows a grey scaly material that is on the lower part of the tree and the roots. Does this indicate a problem. The tree is a very large, beautiful tree.

    The top two shots look like slime flux. It looks like the area of a past pruning or some other injury to the tree. The bottom shot is of lichen. I’ve always heard you find lichen where you find clean air. Here is a little lichen quiz on Walter’s site
