HI all

 

could you help me with this, i found it on a willow, there were 5/6 on it. all about 10ft off the ground, about football sized some of them.

 

cheers,

Laetiporus sulphureus aka - Chicken of the woods

 

have a look on the red link

thanks for that , looks to take on a few different shapes? as there are a few on the one stem would you say its about had it? the willow dosent look in the best of states. its on a public footpath so could be a bit dodgy if it fell on someone

Gary,

 

In causing an intensive brown rot of the central "low quality" wood of the trunk, Laetiporus sulphureus can become quite dangerous on willows. Besides, the shape and the number of the poorly developed annual brackets are signs of panic reproduction, indicating that the mycelium has done (most of) its decomposing work.

The willow in my photo looked perfectly stable from the outside, but turned out to be completely decayed and hollow after the tree broke at the level of the brackets and fell three weeks after the photo was taken.

Agree wholeheartedly with Gerrit on the outcome for this Willow, although not entirely convinced that Garys shot is specifically a poorly developed fruitbody.

 

 

It's possible that it's just early stage like the ones in the first part of this set.

& that it may yet fully develop.

I agree

Agreed, but if becoming fully developed as yet and the number and possible size of full grown brackets taken into account, the tree is even more dangerous, as for developing annual brackets, the mycelium has up to 120 % more cellulose (= about 70 % of the wood) to decompose inside as the total biomass of the brackets developed outside, because in converting the sugar polymere cellulose into the sugar polymere chitine, about 20 % of the cellulose (energy) is lost in the process.

I'd imagine Garys Willow is much like this one were evaluating yesterday.

 

Not a lot of structural integrity left.

No green menaces in that hidy hole, but there are two shots mising from that set above.

 

1st & last............
