saprobic G.applanatum?

[Fungus]

I second Tony's view in this

 

And you can also have a look at documentation of what G. australe can do to other tree species, such as Tilia, Acer and Quercus species, in my Ganoderma australe-Tilia-Acer-Quercus album.

Hi Dean,

 

Sorry if abit late and way off the mark but theses brackets look more like Rigidoporus to me?

Also out of interest if it was Rigidoporous would the alarm bells be ringing so loud?

 

Cheers Steve

1. these brackets look more like Rigidoporus to me? Rigidoporus ulmarius

2. Also out of interest if it was Rigidoporus would the alarm bells be ringing so loud?

 

Steve,

1. That would be easy to assess, as Ganoderma's have rusty brown spores and R. ulmarius has hyalin whitish spores.

2. No idea, because according to Ryvarden & Gilbertson, it would be a first find ever of R. ulmarius on Aesculus in Europe.

Tony,

Not "common as muck" on the European continent though, so what would be your answer to Steve's question if it is R. ulmarius on Aesculus ?

I would be very cautious, but not as panicked as by G. australe on horse.

 

however in the current climate for horse with the extra stress by leaf miners and other known disorders they are currently facing that stress may change the effects.

 

Gerrit, when i was a boy, before i was old enough to appreciate fully the nature of the world i saw on a failed chestunt stum the biggest old white fruit body i have and ever will see, i know now it was rigidiporus. That image is as fresh today as it was back then. i used to skip scholl to chase chub on the river and this tree was in the private grounds where i poached as a child when bunking off school

" saprophytically (if this is actually a word)."

 

it's an e3xcellent word.

 

"the tree seems to be putting on adequate reactive growth - but HC being HC..."

 

It's a battle; wood strength v branch load.

 

"I dont like to knee jerk to say fell and I'd be rather upset to remove this tree only to find that it was unnesesary on disection (as would the client)."

 

as well they should.

 

its a dificult one to answer, i know, without microscopy and possibly a resistograph but its close to a road and a building..... so whats your opinions

 

Since you asked: 1. how much is the tree leaning on that wall?

 

2. probe behind fruiting bodies or any open wound with slender. coathanger size maybe instrument like a long icepick...how far does it go in?

 

3. Look to the crown--how much load can be reduced without hurting the food production and owner's objectives? (how happy would they be with a smaller tree)?

 

1-3 may give you enough to specify pruning works, and tree-to-tree guying to protect targets.

 

4. If you still need info on wood strength, core or drill with a thin bit or reisto. A core might tell you if the advance is like it was in tony's tree, or not. Even if it is, guying can potentially prevent failure on targets, and soil "fixing" might help codit.

 

there's opinions; 2 centavo's worth.

take his advice and youll be in court!

 

better men than you have tried and failed to solve this issue on Horse guy.

 

Some strategies are just too powerfull even for an arb god like you:thumbup:

[Dean O]

Thanks for the replies guys....

hadnt considered r ulmarius -

 

to reduce the tree 'enough', i think, will result in further problems.

unfortunately theres little scope for 'soil fixing' due to the tree being virtually hemmed in by concrete.

 

Unfortunately its either fell or leave alone.
