No, of course not, you have to take all before given characteristics into account. This specimen has :

- big perennial brackets,

- is growing higher up the trunk of the tree,

- has distinct "annual" concentric zones becoming almost black at the centre,

- and will undoubtedly have pale yellowish pores,

so definitely is not H. annosum.

 

:lol:Reversed learning...but it IS the Heterobasidion thread.... I find the Fomitopsis to be a tricky one since it appears in so very different shapes and forms... thanks for putting up with me...:thumbup1:

Tobias,

And then there's the fire test. When you strike a match and hold the flame close to the crust on top of a F. pinicola bracket, the resin rich top layer melts.
