Hamadryads diary- a new chapter

Thanks gerrit, had a feeling you would say Pluteus sp

in post 41 the 4th picture, is that a horizontal crack in the tree? was it there already before the fungus took hold or was it made by the fungus? looks like there was some more brackets there that have fallen off. No reason for asking, just curious:001_rolleyes:

no previous brackets, good observation looks like it has some occluding repairing but the tree is now dead, I shall check next time, I see this failure tree very often.

Had to make a detour home today due to some road closures, so cut through an area I know pretty well and saw a cracking laetiporus on Willow roadside. Some other trees I knew well close by so pulled over for a walk about and got some great shots, was a pleasant way to spend a friday evening, doing what I love most, chatting with rotten old trees!

 

 

 

 

 

 

Right next to the willow was this chestnut severe decay via Ganoderma ustrale, Identification was not difficult due to around a dozen panic fruiting bodies along side the perennial ones. This indicates escape fruiting as the host has been killed and unlike applanatum G australe is not necrotrophic, it is Biotrophic needing a live host.

 

Did that come out right Gerrit?

G. australe is not entirely biotrophic parasitic, but it leads a very poor life with small and (partially) sterile brackets (see photo) once the tree is dead and differs in that way from G. lipsiense, which still can form "normal" and fertile brackets from dead wood alone.

Thanks Gerrit, so the terminology was essentially correct, im getting there!

Takes the title from the biggy at Kew then

 

 

I bet there's much bigger Fb's out there.

 

Guess we gotta up the fung hunting Hamma

David,

As a perennial FB, yes, but not as a living fungus, as this still is a 2.400 years old mycelium (with rhizomorphs) of Armillaria ostoyae in Oregon, with a total span of 2.200 acres or 880 hectares.

Yep, was aware of that little fact Gerrit
