The Ganoderma thread!

[Xerxses]

Apart from the galls of Agathomyia wankowici on G. lipsiense (= G. applanatum), the only way to make sure you're either dealing with G. lipsiense or G. australe (= G. adspersum) is by looking at the size of the spores (microscope). And a warning : especially on Acer, Aesculus (Anne Frank tree, Amsterdam), Quercus rubra and Tilia, the white rot with selective delignification of G. australe is up to ten times as detrimental to the stability of (the trunk of) the tree as that of G. lipsiense is.

Has this been confirmed regarding Anne Franks tree? (Anne Frankboom)

Tobias,

Although the link has no documents or articles attached to it, I can tell you this : yes, it first was identified as G. lipsiense by a German "expert" from a photo, again identified as G. lipsiense by a Dutch mycologist looking at the characteristics of a bracket, then identified by me as G. australe by looking at overview photo's of the tree with over 20 perennial and panic fruiting annual brackets, which are indications of a biotrophic parasitic macrofungus at work and confirmed being G. australe by another Dutch mycologist looking at the spores.

Thanks Gerrit:thumbup1:! Just wanted to double check (I had no reason to doubt in the first place) as I have used the information previously stated in a discussion and dont want to be proved wrong...

Nice documentation . Will you microscopically check the spore size too and also perform the "striking a match near the yellow sub-surface layer" test ?

 

Gerrit,

 

I did perform the 'match test', both on the old and young FB's and it came out negative: it's not G. pfeifferi.

 

I did not microscopically check the spore size yet.

Tom,

Nice , also see my Beech & Pholiota aurivella thread.

Ive been watching this Oak for a few years now, I have watched it decline I think I can no longer wait for the authorities to deal with it, they need to know.

 

Ganoderma resinaceum on Oak (robur) locations a nightmare considering this fungis capacity to kill and undermine the roots of Oaks. Sorry Ted for using a word you dont like, but it is what it is!

 

When evaluating decay via this fungi do not expect it to show up much above ground level, maybe bar a few horshoe shaped pockets that coincide with the swells, which are also distinctive in this decay, distincive enough to be read and identified with considerable acuracy from the body language alone.

 

I learnt first hand the power of this one, and with very liitle decay into the but, hardly of note, but the roots had gone completely.

 

G resinaceum, an oaks worst nightmare:thumbdown:

It will be a shame to see an oak like that go, but that's nature!

 

Would have been an awesome tree before its decline.

 

Do you think complete removal is the only option?

I will leave that dilema to those responsible for the tree! but we all know whats going to happen the second I make the call, sadly.

Ok, , if it was YOUR tree, in this location and you where responsible for it, what would YOU do?
