Sycamores appear to be dying

[Stereo]

We've got many sycamores in our 5 acre wood and today I noticed that on many of them the leaves appear burned on certain limbs mainly lower in the tree. Many trees are affected young and old. Hope the pic comes out ok. Any ideas?

On looking up Cryptostroma corticale One would begin to question working on such trees as Hypersensitivity pneumonitis? seems like real bad **** to me.

Don't they call it bark-strippers lung disease? Nasty nasty stuff.

 

By the way the Sycamores up here have had a fabulous year. See too posting elsewhere about the lack of Tar Spot in central Scotland and elsewhere.
