Not a happy Silver Birch

[Essex arborist]

Anybody know the cause and effect of this (see pics)?

[David Humphries]

I would of thought the bleeding is associated with Armillaria (honey fungus)

 

But the last shot of the fruit body is not Armillaria

 

Looks more like a Russula sp, which is mycorrhizal.

 

 

Did you come across any black bootlace type tendrils in the grass or under the bark?

Have thiese pictures been taken recently or earlier in the year?

Thanks Dave,

 

No sign of any black bootlace type tendrils in the grass or under the bark, the fruit body was found around 12-14ft away and only two of them, all a bit of a mystery.

 

We were originally asked to deadwood because the client had noticed dieback in the canopy during the summer months, the bleeding on the stem is very recent and clearly causing soft decay around the stem base.

 

There is a high target area around the tree so have advised fell and grind. Client would like to replace but until we know what the cause is difficult to advise further.

pics taken last week.

The fungus is likely unrelated to the problem. Im no expert on 'bacterial wetwood' but the slime flux in your photo's is usually closely associated.

[Nimby]

Looks like a Betula utilis 'Jacquemontii' that has been strimmed to death.

 

Might also have been planted too deep, but can't be sure.

 

Is it on a park? Blame the Council.

1. the bleeding is associated with Armillaria (honey fungus) ...

2. a Russula species, which is ectomycorrhizal.

 

1. ... and the type of wood rot looks like the type Armillaria causes.
