A Beautiful Rotter

[treeseer]

Red oak failed; lots of root rot with this subgenus lately.

Looks like Ganoderma applanatum

not an aggressive parasite though and the underside not as flat as I would expect.

 

otherwise I would agree, from the top it certainly is looking G lipsiense

And that's where the microscope has to give the definite answer, because finding the necrotrophic parasitic G. lipsiense on oak is very exceptional and this type of extensive decay in a (living) tree is typical for the biotrophic parasitic G. australe.

Toatly understand & agree Gerrit, & that's why opined that it 'looks like' G. applanatum/lipsiense

agreed:thumbup1:

 

this gano is such a ringer for the Lipsiense, the only giveaway is the lower profile, and thats nowt to go by either!
