Ustulina deusta

What a great idea Lazo, they're your scouts.

Guy, although heartwood isn't living persee' it is a major contributor to structural strength. As the tree ages and the growth increments decrease so also does the sapwood size decrease as a percentile of the radial thickness.

Then you may end up with a tree that's a very thin pipe, no??? I'm talking large dia trees like that big oak, the sapwood may only be 10% and if the other 90% of heartwood is decayed by a saprophytic fungus then that cant be OK, no???

See, around these parts you simply exchange fungus with termites and the same thing happens .... failure!
 
Eric re heartwood,

1. Many saprophytes seem to strongly prefer not the "dead" cells that are inside living stems, but dead branches and stems. I don't think the living/nonliving distinction is that precise or that useful. Heartwood contains compounds resistant to decay. Codit walls do form in heartwood. That's the key issue here isn't it?

2. All that seems to negate the assumption that once a rotter gets a toehold in a stem then the stem is doomed to be hollow in a short time. Host vitality can be boosted, so codit grows more powerful. Microbes antagonistic to the rotter can get established outside of the stem, cutting off its supply lines, its connection to the earth. Many things can happen that lead to the rotter getting walled off and suffocating within impenetrable walls of codit.

When that happens or can happen, the basal cut seems like an overreaction.

Paulo I'm glad to hear the death toll went from 7 to 3. Still 3 too many. Talk to you after work. Dunloop sez you're an ok arbo and i think he's right.

Now this is worth expanding on .... have you some examples.

I dont get to deal with too many fungus infected trees but I like to know all the tools in the bag should I encounter them.

[/ QUOTE ]Several, yes. Armillaria etc. infected trees have been without any signs for years after inoculation of the soil around them. It's all anecdotal--cannot see a way to eliminate enough variables to make it valid research. I approached PHC Inc. about it but they were very nervous about dealing with decay. Liability fears, I suspect. Disappointing.

Eric you should be glad you don't deal much with fungus, but I would rather do that than deal with your drought. Must be all those swimming pools, using up the water.

Steve, this funghi is not known as Ustilina deusta anymore,
It's name has been changed to Kretzschmaria deusta,
This is now what it is known as all over the world.

Steve, unless your living in a galaxy far, far away in a time long, long ago this is the new name for Ustilina deusta.

I dont know the exact reason, something to do with Family and Genus. Its completly different from what they(the unknown botanists who deal with this stuff) thought it was originally.
C'mon Steve we're all professionals now, you have to keep up to date with this kind of thing.

If you don't believe me, just google it.
Kretszchmaria deusta.
 
A rose by any other name would smell as sweet--Juliet.

A rose is a rose is a rose--Gertrude Stein on brownies.

A rotter decays the same no matter what its name is changed to--Anon.

Sticks and stones.
 
its not that i dont believe you axe....but if i used that name over here i'd be met with a blank stare. you've told me its the new name and ive checked it at the site and its in my memory bank....till everyone starts recognizing that as the same as ustulina i'll do everyone a favour and call it ustulina, life is complicated as it is!
its like old rescueman(is he still about?) used to rant and rave everytime someone used the term double fishermans.....its a double overhand!!! thats fine but if u tell your average arborist to tie a double overhand they probably wouldnt know what it was, specially as its called a double fishermans in any arb literature you come across!

I take by "over here" you mean somewhere on Planet Earth!
This is not open for debate Steve.
This is the correct botanical name for this fungi.
Why do you think we have botanical names?
So that everyone no matter where they are on the planet knows what we're talking about, and there is no confusion with common or local names.

Example 1 Sycamore in USA = Platanus x hispanica or Platanus occidentalis. This tree is known as London Plane in the UK

Sycamore in UK = Acer pseudoplatanus. this tree is known as Plane Tree Maple in the USA
If your met with a blank stare then educate the person your talking to.

Example 2 Court case regarding tree that fell on someones house.

If you write that the decay was cause by Ustulina deusta
and the other expert witness said it was caused by Kretzschmaria deusta.
The court would find out who was right and you would lose all credibility as an expert witness, and lose the case for your client as well.
Thanks for your post this has been interesting.

Guy, what the hell are you going on about.

You have 2 options - carry on with your head stuck in the sand approach to arboriculture or be a professional arborist you cares that the information they give their client is actually true.

axe if you look at the parallel thread at gypoclimber.com you will see I noted this name change early on. It's hard to be comprehensive when multiple fora are in play. :(

On reports I would be very precise about nomenclature, because as you say if it came to court it would be bad to be anything but precise. I refer to it as Kretzschmeria aka Hpoxylon aka Ustulina in writing, but if I talked to clients or associates that way I would be harming their interests and my own by being obscure and pedantic.

Informal conversation with peers is another context entirely, so a little less bashing might be in order here. If it's your self-assigned role to enforce an immediate taxonomic transition, please proceed more softly. As Detective Dendro put it, "I am sure there is a scientific reason for these name changes by taxonomists, but some say they are for their own job security."

Guy - Steve's thread had gone for 23 replies and no-one had mentioned this name change.
I thought the original post was interesting, and I was enjoying reading it, but someone had to say something.
If all these people don't know about the name change, then they could potentially run into problems in the future, especially with report writing/court cases.
You have to be as precise as possible with diagnosis in report writing, if the client gets a second opinion and they i.d. the fungi as Kretzchmaria deusta,
you may lose credibility.
I thought this forum was about helping each other.
Sorry about my last post!

To paraphrase JFK,

Ax not what the trees can do for you,

Ask what you can do for the trees!

Is that where your sig comes from?
 
Hey Guy. how about about this....

"We can regard our life as a uselessly disturbing episode in the blissful repose of nothingness"

Only Joking!!!

What I meant to say was...

"If you wish to draw pleasure from life,
You must attach value to the world"

and i was told treeclimbers were as dumb as dirt!
 
"Are you all done yet?"

I'm still waiting to hear about that Welsh law that requires arborist reports to contain a recommendation.

Cmon Laz, whassup wit dat?
