Anyone seen this before?

Sorry Tom, I did receive the images, got a little tied up.

 

I think Skyhuck is on the money.

 

Is there any ground/root disturbance on the affected side of the tree?

 

A little stumped for a positive Id, but I was thinking along the lines of this being the early stages of the fruit bodys of Bjerkandera fumosa.

 

If it is, an image of its later developed stage showing brackets and pore structure would help nail it.

So you think something else is killing the tree? I agree it looks a little like a Bjerkandera.

 

I think its the cause of the die back though, it certainly looks that way anyway..

the dieback could be Phytophthora lateralis. The fungi is probably saprophytic

 

where is the tree Tom?

Edinburgh Tim.

P. lateralis is moving eastwards from the west coast, might be worth getting someone from the FC (Forest Research) to take samples.

 

Red dots show sites identified with lateralis on Lawson's Cypress. In many cases the trees have been felled and all material burnt on site.

Interesting. We were talking about taking samples to the bush anyway.
