Kretzschmaria deusta

[Tony Croft aka hamadryad]

What is it then? small white on the buttress roots, root decayed, and soft?

It seems to be growing in a layer

forming chondrostereum perhaps?

Have you been thinking about that since it was posted in MAY 2009?

Well he joined September 09 so probably not!

 

 

I've seen it on ash that had failed. Did post a thread on it.

 

Seem it on an old sycamore pollard. Would be a crying shame to get rid but it would probably do with a repollard!

hi just read the thread ive just looked at beech that has just lost a big limb and from the pictures it to looks like it has it ,a beech tree thirty foot away from it has just gone over there was no roots left tree council what a pain the tree has a lean!!!!

I'm trying to find some information on when Kretzschmaria sporalates, can anyone help me with this.

We have some stumps to grind out with Kretzschmaria and have been advised to grind them when the fungi isn't sporalating.

As I understand it the white/grey immature form does not produce spores, that's the job of hard black crust. With that in mind, spores could be produced whenever the black crust is present; although I would expect it to stop when it reaches a certain age. (This may be wrong and I stand to be corrected)

 

What is the reason behind waiting to grind the stump? If the Kretz is there and sporulating it will be releasing spores whether you grind or not. I'd have thought the sooner the stump (and fruit bodies) are gone the less the spores will be 'out and about' in the area...

I agree that the sooner the stumps are ground the better, but we were advised to do it when it wasn't sporalating. I understand the immature form doesn't produce spores but the black crust always persists I just wondered if there was a certain time of year spores are produced and if so does it matter? Or just grind out as soon as poss?

you do have some cracking examples david.

Maybe pick out any black crusties before grinnding that oughta do it.

 

The fungus is everywhere so this does not sound like an enormous issue.

I think this is Kretzmaria deusta on Beech

 

 

But then wondered if it could be early stages of Bjerkandera adusta because the brownish colour doesn't seem to fit with Kretz and there was no black charcoal crust present, however the cross section has the black demarcation lines associated with Kretz ( pic will follow). Found at 15m again which also isn't normal for Kretz but I have found it at this height before.

 

Possible that both fungi were present.

 

Any thoughts?
