Laburnum fungus id and treatment please

[arctree]

Hi

Just discovered this on my faithful chain-of-gold Laburnum.

 

Can anyone identify it and suggest a treatment.  The fight begins.

Probably remove that branch, looks like the bark is dying all around it anyway. They do seem to lose branches now and then, make space for new ones to sprout.

It's a fight you can't win.

 

Every Laburnum htat I have attended that has been ill has had this orange bark. Which means the bark is dead. There's a long list of possible culprits, notably Phytophthora. So it could be manifestation of root rot. Or in your case it could be bark death caused by compression of wood against bark at those ugly looking forks.

 

Looks like a mature tree, at a goodly age for a Laburnum. They only last a few decades. They're rarely a risk even when they are jsut about dead, so I'd say don't prune of fstuff until completely dead and de-barked. Soil drainage might be the main issue. Give it good hard shoogle, if it moves then I suspect root rot.
