Positive id would be good. On robinia.

 

That "may" be Perenniporia, Graham.

 

Can you get a wedge showing the flesh & tube layer?

 

Or is too late?

 

 

Here's a Robinia from yesterday with Perenni, which has the more typical flat bracket at the base & then one of a number of lump fb's forming up between the flutes on the Trunk that are similar to yours.

Great shots sean, when was that failure?

 

 

 

.

 

 

back in May.....a great fomes beech in the park. Had another failure a couple of weeks ago...... doing a very light reduction on it next week with the mewp.....have also managed to persuade simon to erect a very small fence around it to prevent people climbing on (kids) and generally interfereing with the brackets as they are v.special:thumbup:

That cross section is a very interesting shot Tony.

 

How high is that stump in the shot?

Can't quite tell from the angle.

 

I've not ever knowingly witnessed a resinaceum failure before.

 

So are we suggesting here, that trunk & roots are compromissed by the resion this one?

 

Can we rule out something else for the roots?

 

Was everyone Ok from that house?

 

the stump was 1-2ft high

 

funny as this was my first real propper look at resi rot, but certain it is that familiar wide rooted form in the language that reveals the strategy:001_cool:

 

As can be seen from the decay it is mostly root bound, very intense simaltaneous rot that appears to be almost confind to the sapwood layer. Not unlike the decay via colybia fusipes, the areas of most intense rot in the cross section are where the three fruit bodies where presented, I have leanrt much from this case, as I hope sharing it has for the rest of us here. And yes i am happy to confirm all this decay is via the resinaceum and not a secondary colonisation.

 

all where fine, if a little shook up,:thumbup:

Good move from Mr Richards, I'm sure he has a fair amount of pressure not to enclose & block access at the site.

Dificult decision for him I'd imagine.

Great to see the Tree's being given more time.

 

But then that's what makes Richmond sooooo special :thumbup1:

Interesting that neither of us have witnessed this associations potential for failure, particularly root failure.

 

Think I'll try to get the airspade & digi micro probe out, (when I have the time & oportunity) to investigate one with low sited brackets.

Would be wise, especialy as g. resinaceum holds the middle ground in invasivness between australe and applanatum according to work by shwarze.

 

as can be seen it appears to have trouble with the phenols in the heartwood but little trouble with the sapwood layer, this is a very significant point as all the tension woods are open to potential degradation via the G. resinaceum.

 

I wont be ovewrlooking the low swell language of oaks anymore, not that I did, rather i will treat them with more cautionary observation in all future findings.

 

IMO ganoderma resinaceum is a VERY significant decay fungi, one we should all be paying attention to, level 4 pathogen im my rating system now.
