Brackets on a black poplar?

[Giles Hill]

I'm having trouble with this one - growing on a black poplar.

 

The first two pics show a large fresh looking bracket at the base of the tree.

 

The 3rd and 4th show smaller, older looking brackets growing from a cavity.

 

I keep coming back to Rigidoporus ulmarius, or at least the available pictures and descriptions look similar.

 

(pics2-4) to follow.

Certainly looks like Rigidiporous to me.

 

I haven't seen it on Poplar before.

 

Mainly noted it on Aesculus.

Thank you, I haven't seen Rigidoporous before and none of my books list Poplar as a host.

saw that first pic and thought of scrambled egg for some reason.

A big egg - it must have been laid by a chicken of the woods.

the smaller lower pictures are certainly characteristic of older rigidporous ulmaris, the green colouring is down to algal growth. It is usually found on elm (ulmus) but does occur although only occasionally on quercus, acer and populus. apparently since dutch elm it has become fairly rare. it causes a brown rot which can increase the risk of windthrow.

Looks just like the Rigidporous ulmaris I incorrectly ID'd on my PTI course.

tis actualy as common on poplars as on aesculus, white rot. this can grow to immense proportions, probably the biggest of all the bracket fungi.

talking of big brackets....
