The vagaries of Fungi never cease to amaze me Andy.

The books can never have it all covered, hence the sincere question.

Well P+D was never my strong point, so i'm more than happy to hold hands above head and say it was an "educated guess", based on "opening gob before engaging brain" syndrome.

 

Besides, i'd just written war and peace on the 'do students learn anything' thread, so i think perhaps that i may have been somewhat distracted.

 

 

But the brown powdery rot, does look very much like..... :blushing:

I'd lay money there was at sometime a bracket on that trunk

 

I was thinking the same, but then wondered how unusual it is to get extensive decay like this, without having a parasitic fungi involved? I'm meaning where something else compromises the tree's vigour, so it can't adapt to the decay caused by saprophitic fungi.

 

I guess that happens a fair bit, but I've not been aware of seeing it - possibly because the trees get cut down because of their poor appearance, before they rot as much as this one?

Hi guys

 

I consider that this is a prime example of colonisation by Ustulina deusta (decayed wood yellowish - brown colour, Schwarze, Fungal Strategies of wood decay in trees) and fits my own findings. It doesn't matter anyway, the decay looks extensive and if this is the case SULE is 0!!!

 

Fell & replace, be interested to see if it has the black zonation lines to see if I'm right.....

 

Cheers Dude
