Q stellata, mid-stem

[treeseer]

Central leader declining due to root loss and being squeezed by codominants. Small area below conk has canker maybe 1' x 1.5' with woundwood margins.

[treeseer]

Also the tree has a cavity 5' wide at the base (85%?), opening at the east side, facing the wires. Someone shot video with a borescope and the sight of the buttress decay freaked out the Town arborist, who pressed for more taken off than i'd specified. we compromised.

Innonotus sp Guy?

 

Do you have many sp within the complex on the east seaboard?

 

 

Looks like dryadeus.

 

 

Any decay detection up around the conk?

Not like any I've seen before. what kind of closeup would help ID?

 

"Do you have many sp within the complex on the east seaboard?"

yes 6 or so but dryadeus is the only common urban one ime.

just sounding with the mallet. wood is extremely durable, hence common name of "post oak" the dead chunk i cut out was Solid still, no rot.

 

The lower trunk was heavily assessed in a "drill and kill" style job. condemned according to tomography at 20" above grade, and drilling of buttress roots. :cursing:

Here are 4 seperate desicated I. dryadeus brackets, both from at height and at base of Oak.

 

Even desicated you should be able to make out the flesh being fibrous and rust brown (originally buff)

Spore tubes are a darker brown than the flesh.

 

your 3rd shot 'appears' to resemble the 11th shot below

Well that surely leaves little doubt, thanks. The upper surface of this one was curling upward, which did not look like I.d. at all, but now i see it was dessication that makes it look like that.

There are no structural implications i can see with this chap at the mid-stem location, as there is little mass left above it. No conk has been seen further down the trunk, and this is a high-vis location so it would have been noticed.

So beyond the reduction and the removal of anaerobic mulch i do not knwo what else to do for it. town refuses to consider root work--they stopped my guy from aerating n/c while i was pruning.

[treeseer]

Your full-tree pic shows the location is similar--in a central leader that is being squeezed in. A thousand words at least.

 

I never sorted out I dryophilus; what differences in the conk to look for.

Have not had the pleasure of I. dryophilus.

I don't believe it has been noted here in the Uk

 

From what I've read, the two appear to be similar, with the height issue (location on host) often cited as being a difference.

 

Like in your (Luley?) book above

[treeseer]

I was hoping for a morphological difference; guess i gotta poke around west of the pond. yes, luley's manual.

 

these little cuties were coming up near the trenching damage. early autumn pic.

My thoughts are hispidus just to throw a spanner in there, on reflection that dryophilus is an interesting match
