Another Ustulina/K. deusta on Syc.

We seem to have had a spate of fells recently involving Ustulina infected sycamore. Almost to the point that I'm travelling round tuned into the base of every syc I see

Nice pictures Graham, was the tree felled on the basis of any other VTA, or was it just the presence of the Ustulina?

Re: Another Ustulina/K. deusta on Syc.

Great post Graham.

Wonder if the evident psuedosclaratial plates are indicative of a. n. other fungi competing against the Ustulina?

Really good shots

Re: Another Ustulina/K. deusta on Syc.

Tree was situated on a raised area bounded by a low retaining wall. There was evidence of root damage caused by the construction of the wall (1990 evidently) and severe dieback in the right-hand stem shown in the photo.

It was on the entrance to residential flats and a public car park.

That I don't know. Certainly in the fells we've done recently there hasn't been any visual signs of other fungi evident. ie fruiting bodies but they have all had one thing in common; visual root damage or soil disturbance around the root plates.

David, which bit are you calling 'psuedosclaratial plates'? I just googled that term and the only thing that came up was one of your posts from last year!

Technical terms for the black lines/spalting effect.

Thanks Paul.

I've just found mention of this in my Lonsdale book.

It sounds like a kind of CODIT activated by and for the benefit of the fungi, rather than the tree?
