Massaria

Could well be, but were there no necrotric cambium lesions present on the sides of the branch where the infection seems to have invaded it ?

 

Nothing really noted Gerrit.

 

Also was expecting to note cambium roll attempting to occlude at the live/dysfunction interface, but again, nothing really.

What about Inonotus hispidus ?

That has been suggested to us as an alternative and I've noted hispidus fruiting on Sorbus & Fraxinus not far from this Plane. But have not seen it fruiting on Plane in this park before.

In plane, this type of wood decay is typical of Inonotus hispidus, because its mycelium follows the starch rich radial rays outside in and inside out.

Have seen similar failures (top side dysfunction & delamination) on Beech also.

 

Interested in your thoughts on culprit on these two Gerrit ?

similar failures (top side dysfunction & delamination) on Beech ... your thoughts on culprit on these two

 

The first one could be Oudemansiella mucida, as to the left there are branches present that already are dead.

The second is probably caused by torsion and overload, not by a fungus.

Oudemansiella is good possible

 

The Beech limb (that was still attached), has that historic wound which I was thinking may have had fungal ingress & associated decay, as that seems to be the site of fauilure.

In that case, I would have expected a decolouration (white rot) of the heart wood of the branch.
