Missed that one Ben, thanks for re-posting

David,

... which IME is rather common in Acer and in Aesculus, Tilia and Ulmus too.

 

1. I meant it being rather common with respect to the extent of wood decay in the four tree species.

 

Here in the South East & East of Britain the host association is strong too with Acer, Aesculus & Tilia, but not so much with Ulmus. (in fact fairly rare, ime) I presume largely down to the disapearance of the older Elms through DED.

Whether the above situation has had an effect on the fact that Fagus now appears to be a significant host tree, I'm not sure.

 

Is this similar to the situation in Holland/Germany ?

Yes, it is while mostly fruiting from large pruining wounds and it's also quite common on Fraxinus and far less common on Salix and Populus.

Kinda

 

 

Whilst you're here, do you note P. squamosus on Elm in your neck of the woods Iain ?

 

I'm sure I came across a good few large mature Elms last time I was up in the North East.

Any thoughts on Polyporus on Ash? Fast and extensive or slow and mainly heartwood?

slow, would need to be VERY extensive and have a crown form of leverages to be a serious issue, a pollard for example would be no worry even with lots of regrowth say 15 years worth even 20, but heavy mature un retrenched crowns defo needs reduction to sor the potential limb losses:thumbup1:

 

not that aggressive a decay really

Found on Lombardy poplar, pretty sure its P squamosus?

Interesting how geology changes mycological habit, Only ever see P. Squamosus on acer round here, last summer I condemed 3 large Sycamores that had extensive decay due to P. Squamosus, one could hardly see the trunk for fruiting.

 

Brilliant pics Dave
