Yeah pretty much.

 

only really seen three or four P. s failures though

 

Ryvarden & Gilbertson state "Thin, whittish, resinous mycelial felts are present in shrinkcage cracks"

 

& Butin says the same but adds that the mycelium is "chalky-fluffy" & that the brown-rot has a "smell of turpentine"

Thought someone might like a look at this. A just about dead Cherry I cut down today with what looks like a Ganoderma of some description at the base. Main stem was hollow most of the way up (full of decomposed tree). Wasn't sure that I should have climbed it when I saw this!

And here's another one, courtesy of the storm. Robinia pseudoacacia 'Frisia'. Started to go over and seems to have had a problem with Armillaria. Have seen four of these in the last few days that have gone over in the wind. Anyone any idea why they are so susceptible?

Possibly has the white mycelial sheets of Laetiporus in the cracks in that cross section.

 

 

Armillaria and Letiporus often found on Robinia together.

a close up of the brown rot and associated mycelial felts

This is a very very nice set David, a good example of the decay.

 

I would however like to take you up on a small point, is this really a brittle fracture? or a case of buckling after shear as is classic to the T/r theory?

 

 

:ahhhhh::tee:
