Lombardy Poplar concern

[Fungus]

We have just felled a dozen pops, not lombardy though and although they where only 20 odd years old, most had a large hollow filled with wet black shoite. The crowns looked good and healthy and there where no fruiting bodies nor wounds nothing to indicate ill health. My question is therefore, what is it?

 

Ty,

It's "poplar wet wood" caused by a bacteria, that protects and defends the heartwood of the tree against attacks and invasions of mycelia of saprotrophic wood degrading macrofungi white rotting and/or hollowing the tree otherwise (see photo).

a wood burner????? we've got some nice ones around a shed dad planted years ago, but there also burn well when a bit needs chopping off when leaning on the shed!!!

which is why poplars are so poor at dealing with pruning wounds, once aerated the bacteria dont do so well.

interesting hama - when it comes to pruning pops is there ever a case for leaving stubs on smaller stuff to help compartmentalise/barrier etc?

Any pruning wound with for some time exposed and unprotected heartwood can easily be invaded by spores and mycelium of fast and extensive white rotters such as the tree species specific annual Pholiota populnea (= P. destruens) or perennial Phellinus species such as P. igniarius.
