Great photo set Bart

 

Not digging Ya here, but in your thread 'Any Ideas' you state

"Quite new to fungi id and am trying to expand my knowledge"

 

So, my question is.....

What makes you sure the above is G applanatum as opposed to G adspersum?

 

 

Interested in what drew you to this conclusion.

What reference(s) you use etc.....

are you refering / looking at the core of decay there Dave ?

That, but also the area of Fb ie the exposed heartwood at the trunk fissure.

 

What would be very interesting to know, is whether the Tree was very exposed to wind force from the position of the camera shot. Bart?

Glad you like the pics:001_smile:

 

Compared to you guys i dont know much, but over the past few months have been getting quite interested in it.

We have a lot of over mature tree's, and a variaty of different woodland types on the private estate where i work,

so learning more can only be a good thing.

 

Im not too sure that is G applanatum as opposed to G adspersum, ive got a collins field guide to mushrooms and toadstools which i find quite confusing at the moment, so ive looked at http://www.rogersmushrooms.com where it suggested to me that applanatum causes an intensive white rot, but now i think adspersum can too having looked here http://www.biology.ed.ac.uk/research/groups/jdeacon/microbes/armill.htm.

I cant see much visable difference between the two other than adspersum has a lighter colour, so the conclusion from my pic's was applanatum.

No the photo was taken facing roughly west, the tree is'nt particularly exposed.

Hope this helps.

A consultant recently told me that you can easily tell the difference between the 2 - news to me as I thought you needed a microscope to tell them apart.

 

He reckons that G. applanatum has a more fragile upper crust. If you apply some pressure with your thumb and your thumb goes through the crust then it is applanatum (I have memorised it as "applanathumb" to help). If you can't press your thumb through it is probably adspersum.

 

Anyone else heard this - or know if it is true!?

 

Nice pics by the way Bart.
