Something that looks like Fire Blight, but isn't?

northernmn(3/4)July 11, 2013

This spring before leaf out, I noticed what appeared to be the start of fire blight on 2 branches of my Haralson apple tree. The "sooty" appearance was only in the middle 1ft of the two 5 ft branches that had it. The branches have now been leafed out for a couple of months and there is no change in the size of the "sooty" looking area. All of the leaves on the branch (before and after to sooty area) look perfect. No symptoms at the tips at all.

These pictures are from prior to leaf out, but the actual affected area has not changed. Any ideas what this is? How would you treat it?

It looks like some kind of bark fungus to me.. probably harmless.

Thanks Scott. Do I need to treat it with anything or just watch for now to see if it spreads? I have sprayed it once with a fungicide but I didn't notice any change.

I'd cut it off at the Y on that branch, but thats just me.
