Fungi?

[stevelucocq]

Hi,

 

Spotted this early forming fungus on a living Quercus ilex a few weeks ago. It has plenty of mature Ganoderma adspersum brackets around the buttress and further up the main trunk. I have seen early forms of this similar looking fungus turn into Ganoderma species one being resinaceum. I was wondering what people think this is going to turn into? Inonotus dryadeus as another option? Thanks Steve

I would say that's dryadeus all over.

What are the targets, Steve?

A busy path, all butresses covered in mature Ganoderma adspersum brackets....The only reason why I say about Ganoderma (and not all the tell tale signs of dryadeus) is that I have seen near by very similar early fruiting bodies turn into Ganoderma resinaceum and was thinking this may turn the sameway. It is close to where I work so I will keep updated pictures of it....cheers steve

I made the same mistake, I identified these as young I. dyadeus fruit bodies:

 

 

Largely because of these 2 amber coloured drips on the bottom of one bracket:

 

 

But they turned into these:

 

 

I think your's is a proper I. dryadeus because it's got the classic 'lots of drips' from the top, whereas my G. resinaceum (assuming that's what it is!) only had a few drops from the underneath and none from the top. But I might be wrong...

This eventually turned into G. resinaceum on Red Oak.

That first pic of yours David, looks just like a nice fresh bread roll, which is exactly what I thought when I found the one above - my picture is a bit over-exposed though, so the colours don't come out.

Innonotus dryadus always looks like fresh bread rolls to me, just like the piccies above. The water droplets are another classic indication that this is dryadus - it is actively removing water from the wood to make a better enviroment for itself.

 

I have never been able to find much info' on the significance of the decay it causes though - so perhaps someone here can enlighten me?

 

PS - i have some piccies of mature I. dryadus on Q. robur in my gallery .

"I have never been able to find much info' on the significance of the decay it causes though - so perhaps someone here can enlighten me?...."

 

Refer "Fungal strategies Wood Decay in Trees " ( Schwarze, Engels Mattheck-Springer press isbn3-540-67205-2 )

Page 131- 135....(page 134- sub para N0 1 in particular) Hope this helps....

The significance was not made a great deal of during the PTI for example, although the fungus is of significance within europe....If you are meaning the risks associated with the decay, it is perhaps regarded as quite slow. Advanced decay will result in windthrow in all liklihood according to my studies/info-the paragraph I refer to has further information on this aspect in particular....( Sorry if you have already read this reference...)

Hi, here is a update……ok it looks like it is Inonotus dryadeus as a few of you mentioned G.resinaceum looks more bread like when young…also other FB on same tree showing I think Ganoderma adsperum (smooth, hard crust, functional wood). There are a few of these brackets up and down the trunk and I understand I.dryadeus seriously weakens the wood in advanced stages and G.adsperum is more aggressive than G.applanatum, so it not looking good…….also notice the target….what’s people opinions on this one?

[Giles Hill]

I like the adaptive growth there Steve, it looks like it might eventually compartmentalise itself into some kind of weird multi-stem!

 

I don't know how relevant the t/R calculation would be with that one...
