Guy can Hypoxylon canker cause that much damage on a branch eventually?

Re: What Did This?
Starlet, you may be warm. Key clue may be that the branch is layering, i.e. the branch hit the ground and is growing roots. Also note the smaller round hole, and the growing connection.
This is more a syndrome than a pathogen imo.

Re: What Did This?
I thought it meant 'huh? or 'I give' but I dunno.
Is the damage somehow related to unnatural weight on the branch? The round hole - is that where a small branch same out once and then died or was broken off?
I'm finding it hard to orient that image properly. I might be looking at it wrong.

Re: What Did This?
i can not see where it grew into the ground, i agree the small hole looks like some sort of damage but i dont think it is a broken limb?? damage from unnatural weight i could see that happening...

For Pete's sake, somebody post a picture of a bug or something.

It appears the branch stubs on the live oak are infection sites for some type of fungus-polypore perhaps?

Re: What Did This?
There might be a good story here, but for practical purposes, most of what we are seeing is tree response to mechanical injury and infection. I may just be lazy, but I don't try to puzzle them out. Of course, exposed wood will be colonized by a sequence of fungi following the initial injury from a falling limb, scratching animal, etc.

It's the LACK of response in a layered limb that is the story. Colonization happens when codit does not, so the fascinating (to me)part is why it did not, in a tree of high vitality. That's what is fun to puzzle out, but I must be alone in that fascination. O well, time to find a bug or something really obvious to talk about...

Re: What Did This?
Well, I find that interesting too. Do you suppose its because the wound was continuously opening a tiny bit at a time with the weight - kind of like when you get a skinned knee and the scabs keep opening when you bend the knee.
Or maybe the tree decided to put its budget into layering instead of CODIT.
I have zillions of bug images but I'd have to check and make sure they are not too western or too obvious before I post anything.

Bingo! When an abrasion wound on a live oak merges with a pruning wound, you know defenses are not there. resources are moving toward the propagules--as with humans.

I've got one but with little data--florida champ live oak, the cellon oak/ This is the upper side of the lowest limb, the tip of which is layering.
What is causing this canker?
[/ QUOTE ]
I've seen similar damage caused by a fallen tree caught in a crotch that has hung for years then decayed away. That damage is likely many decades old. Just a guess.

very good, okay i understand what you are describing now, very interesting, i have not seen this before. guy this is why i really do like different, this is when you learn. i will look for some pictures also.

Re: What Did This?
Guy i am throwing this out there but let me know if my thinking is on the right track, if indeed it is creating a new section attatched to the ground with root system, it would seem to me you would have to leave it attatched until it has matured to some degree, and then i would say in the meantime keep the tree as stress free as possible, lots of healthy nurturing, compost,water etc. then the question i would ask would be can you disconnect the new growth without damage to the parent? anyway i know what i am trying to say hopefully it makes sense. i guess doing nothing except making sure it is not under any stress would be it...

[/ QUOTE ]Yup, I agree, then the tree will finish shedding it. The Fairchild Oak has one that's about used up and ready to fall. I offered to tether it but they refused, so I documented that, just in case...
