V.T.A symptoms "the chatty trees"

[RobArb]

cheers gerrit but what about the flat bark?

[RobArb]

and last question of the night:lol:

 

number 3

 

this A. platanoides again had a full healthy crown but with what seem to be weird shear cracks in the stem that seem to be trying to "seal"

 

they were on both sides of the tree opposite to each other with one shear split in half and the other looked like it could be a possible shear bomb crack

 

Also on one side of the tree near a crack there were 3 separate areas of what seemed to be flat bark.

 

So whats going/gone on?

what about the flat bark?

 

Rob,

First phase of infection of the cambium with wound tissue or callus trying to overgrow and close the necrosis caused by the bacteria.

Rob,

The last phenomenon is caused by the mycelium and/or rhizomorphs of a parasitic Armillaria species, which also can be responsible for the splitting and cracking if it is decomposing the central wood as a an optional saprotrophic white rotter too, changing the flexibility/stiffness ratio of the trunk.

Got some shots of two Norway Maples. One of them is in a heavily used car park with Coprinus spp growing at the base with an obvious sink. The other looks like it has split sometime in its life and is now healed back up.

Matt,

Coprinus micaceus s.l. is a superficial secondary white rotter, which is part of the succession phase of dead wood, which already has been partially to almost completely decomposed by other saprobiotic fungi.

Would you say the tree needs to be reduced asap or monitor. It is a twin stem from about 12ft onwards. No signs of die back but our TO said that the Coprinus is just feeding off the leaf mulch and moss around the base of the tree but there are atleast 3 feeding points.

Rob,

See : Aesculus bleeding canker.

 

think hes right rob:thumbup:

Matt,

Only based on photo's, I cannot be the judge of that, but you can tell your TO, that Coprinus species belonging to the C. micaceus s.l. group are secondary decomposers of decayed wood, i.e. indicators of other saprotrophic macrofungi still being or having been active. So I would look for signs of other white rotters.

Will do. We have suspected that where the tree becomes two stems there is a cavity there. But no other fruiting bodies have come up at any time of the year. Will keep an eye on it when Honey Fungus starts appearing elsewhere on the site.
