Just wanted to check what this is please?

It's on the Base of a London plane, thought ganoderma at first but not so sure on closer inspection

[Betula]

Is resinaceum, seen it on Plane before

[Kveldssanger]

Nice example of Ganoderma resinaceum, there. Not seen it associate with genus Platanus before, so thanks for sharing!

It's the first time I have come across this ganoderma my self.

 

Will pop back next to have a closer look now.

 

How much of a problem does it pose on a plane?

 

Thanks for all your help to

You find with this species that decay extends from the butt into the principal rooting system, thereby making the host eventually adopt an 'Eiffel Tower' look - assuming compartmentalisation is poor, and plane typically is quite good at defending itself from fungal pathogens. However, this fungus can break through the defensive mechanics laid down by plane, albeit less virulently than Ganoderma australe. In this sense, Schwarze, in his book entitled Diagnosis and Prognosis..., suggests that unless the tree is displaying outward symptoms of decline (crown density, vigour, etc), then it may be wise to simply monitor the situation.

 

Granted, a major target zone beneath may prompt a crown reduction to remove some of the drag effect, though factor into account that the plane will need its leaves to create the energy required to combat the mycelium progressing within its structure (and grow / defend itself from other stresses / etc).

 

Do you have more pictures of the tree, from afar, and showing crown condition and overall architecture?

Hi, I will add some photos next when im back there.

It is a street tree 5m from the houses. Its a lapsed pollard.

 

Its probably 16-17m tall. The crown looks healthy but my concern would its location, although not a busy street, it can be at peak times.

 

Just been reading your earlier post and the link research paper which is very useful.
