Fungus ident please

[Dominic Phillips]

Saw this fungus on a very big Popla.

 

Was wondering if you could tell me what it is and what it might be doing to the tree.

 

It seems to be coming out of the bark, and at the base of the tree.

Looks like Honey Fungus Armillaria gallica? not quite as nasty as mellea but still a significant root rot pathogen.

 

Have you checked in the ground for bootlaces?

 

Not 100% sure, but interested to hear what others think of course.

Looks like older honey fungus armillaria to me too. At a push it could be pholiota squarrosa commonly known as shaggy pholiota but the aged caps don't give much away. I'm looking particularly at pic three where there appears to be a decaying cap on the ground with the 'shagginess' on it *tech term alert *tech term alert

 

As Nimby says, check for tell-tale boot laces.

Looking again, is that a Lombardy? also, is that stress growth at the base or is it in a privat hedge? What are the targets?

 

I have seen something similar on a Lombardy and the tree was completely goosed <-- technical term.

 

Is there any mechanical/physical damage to the tree or around the base ie, new road surface, compaction etc.

 

Anyway if it's a Pop I would just fell it and replace it appropriately. Inspect it properly (whack it with a hammer/steel boot) before climbing it though.

Its of a very big Black Poplar, the stem of it is about 1m across.

 

The picture doesn't really give the size of the fungus, the big one in the middle is probably close to 8ins in size (if not a little bigger).

 

This made me think that it might be a bit big for armillaria ??

 

i think that there may have been some growth at the base before.

 

There is a road fairly close to the tree, and a cannal the other side with another road.

Its not Armillaria or Pholiota.....and on a black poplar I would urge that you seek appropriate level of professional opinion b4 condeming the tree...if indeed thats the way this thread/tree is going? Cheers.

[Nimby]

I agree, indentify the tree properly and ask advice from the LA TO.

 

Native Black Pops are a UK BAP priority species and very important trees.

More than likey a Hybrid, but if its a true Black, then might be worth retaining if possible.

I think these are quite possibly Gymnopilus junonius - Spectacular rustgill.

 

Which I believe are saprobic on dead wood.
