What's happening with this sycamore?

[Laura 12345]

Hi all,

 

Spotted a very interesting old sycamore the other day (990mm dbh). I've never seen anything like this before on the stem + major limbs - some of it looked like extensive burrs of epicormic, but on the limbs it looked more akin to cankering in places. There were no fruiting bodies anywhere. Has anyone seen anything like this before? Any ideas as to what it could be? 

 

 

Thanks!

chances are its a major case of SEP.

Please forgive my ignorance, but what does SEP stand for?

I'm puzzled too

Usually Someone Else's Problem, makes something invisible to most people when an SEP field is around an object.

 

Not sure that applies here though.

Sycamore Eutypella parasitica? Bit of a long shot in the UK?

Pretty rude. Certainly not helpful. Like you don't understand why people ask for help from fellow professionals.

I forgot to say, not really seen it on sycamore but seen ash do something a bit similar, which I've always assumed was canker.
