Inonotus dryadeus-

[Fungus]

the low cohesion and shear strength of the soil itself that has caused the failure, rather than decay (obviously all old trees lose the central roots)

 

No, decay by Meripilus (see the photo of the panic reproduction in autumn) caused the fall, because the soil was very wet and cohesive and the beech was not yet in foliage, when it fell in March after a period of intensive rainfall. And what do you mean with Fagus having "central" roots as opposed to lateral roots ?

I didnt say beech have central roots, only that all old trees tend to have roots at the periphery/drip line/or extended root crown as apposed to the youthful Heart-rooted/tap rooted form of youth.

 

I also said sandy soil is crap! and thought you posted a fraxinus not a beech, hence my diagram as I thought we was talking fine rooted (reiterative roots) of ash as opposed to cone form and its fine roots in ash with pholiota squarosus.

 

wires crossed thats all.

 

sharp sand locks and increases cohesion when wet, round sand does not and has low cohesion at all times. the beech with meripilus has far more roots than I would expect in a failure with meripilus, the soil and shape of sand sped up that failure IMO

In my region, sandy soils always are composed of sharp edged (silicium) sand without destabilizing inclosures of humus or composted leaf litter. I've never seen a beech fall in this particular way, which was not heavely decayed in his root plate by Meripilus.

end of the day im only going on what i see here, so its pretty irrelevant what i think anyways.

 

just surprised to see so much healthy fine roots at the periphery and a fail.

[Tony Croft aka hamadryad]

Took tom our new apprentice to see this oak from earlier in the thread i believe.

 

hadnt checked it while it was still warm and have missed a new bracket forming now gone over on the upper roots! thats not so good.

 

the cavitation is increasing now and i can just about reach my hand inbetween butresses.

 

these images show the scars from five years annual fruitings. It has been an interesting tree to study because I have been able to see the progress, fruit bodies only forming in a new spot on the diameter and i have a theory about that but shall be giving it more thought over the next few years as and when this tree tells me more.

 

as you can see this tree i reduced and now it has two years (full seasons) growth and is shooting nicely this will enable further reductions as will be needed with progressive decay.

Host Q phellos in SE USA is ringed 360 with it;

 

1 old and new in first pic

 

2 squirrel on burling stub, showing limb loss; has been dying back for a decade

 

3 nice rib of adaptive growth

 

4 a "shield" growth at the top of a sinus. often i see these at stressed points like this, but sometimes unrelated to rot or movement. is there a name for these in Europe, or a thread here about these flat, liquid-looking burls(?)?

like these?

 

note the new expansion of growth, thats what im referring to, Tony called these inosculations, but they are called something else, which i never found a name for!

what he forgets to say is i USED to call them inosculation but This is an incorrect term for them apparently

[treeseer]

... new expansion of growth, thats what im referring to, Tony call*ed* these inosculations, but they are called something else, which i never found a name for!

 

Rob, yes, very similar, thanks. Your pic shows it spreading callus from a collar, but it often takes off from a point not near an apparent node.

 

Note *past tense*, hama. So you are off the hook. Inosculation has "blend" in its definition so close but no cigar.

 

I prefer "shield"; connotes armoring and protection, and flatness.

 

I. dryadeus looks similar uk or us--one thing we have in common at least!
