Massaria on the March

[alliaria]

Its in Bristol, large limbs, very worrying.

Found a hell of a lot on a row of 25 medium sized ones (the most for me in the last 6 months). A lot of it eminating from past pruning cuts where the limbs had been lifted. Trauma bringing it on??

I forgot to add that these are situated in very well irrigated flower/shrub beds, which throws a spanner in my drought response theory.

Thats interesting isn't it.

 

What area of London is that?

 

Have you any images of the branches affected?

Ive only ever seen that combo in you shots, never in the field. Is the auricularia causing a secondary white rot??

The planes are in st johns wood opp lords cricket ground. No pics im affraid as i keep breaking my smartfone. need to get a normal camera.

[David Humphries]

Is the auricularia causing a secondary white rot??

 

Yes, and seems to be this that is causing larger diameter branches to fail as opposed to where we are finding just Massaria.

 

We are starting to see the combination of pathogen and secondary infection with increasing frequency.

 

Will be focussing more on the branches we see auricularia on now

 

Good thing is that its a fairly persistent fruit body and can be seen from the ground relatively easily.

Found lots more on 4 x 35m trees. Each had at least one 6in dia limb that had to be removed.

[David Humphries]

Any other fungi in attendance on the trees?

 

Auricularia, Inonotus?

 

 

Street trees or park?

[coleman]

No other fungi was present. These are situated in a private square garden Nr Marble Arch. We had cleaned them out a year ago. There was evidence that the massaria had spread from the wounds from sub laterals we had removed a year earlier and was killing off the main lateral...if you get what i mean.
