Dual Decay

[David Humphries]

Birch with Fomes fomenatrius and Piptoporus betulinus on the same branch.

 

A more common occurrence in the north of the UK but less common to see both species on the same tree host here in the south east.

 

 

The Fomes decay is a simultaneous white rot and the Piptoporus decay is a brown rot, both are clearly evident here in seperate branch sections found on the floor.

 

 

The tip of the branch is where the majority of the Piptoporus colonisation and fruiting is located and the base of the branch is mostly colonised by the Fomes.

 

Sliced and diced to have a closer look at the over lapping decay colonisations along the branch.

 

 

Francis Schwarze (Fungal strategies of Wood Decay in Trees) mentions that a common occurance in advanced colonisation of Fomes decay are cracks filled with white/yellow mycelial skins, which can be clearly seen in these last cross sections taken close to the branch union just below the fruiting body.

Heterobasidion annosum & Kretzschmaria deusta vying for the same rooty wood volume here on this beech from earlier today.

 

Not much rooty stuff left I suspect

That's interesting David, I took this photo late last year - an alder with what I thought were developing Ganoderma FBs.

 

Maybe I misidentified it. I'll try to find a photo of the FB

Did you look around the back of the tree for Meripulus?

As well as the Hetero and Kretz this one also has colonisations of Ganoderma australe, Herricium chirahtus, Flammulina velutipes, Fomes fomentarius and Meripilus Jake.

That was supposed to be a joke Sounds like a pretty doomed tree! whats the plan?

It's already an 8m monolith Jake, we'll reduce it some more when I feel it's completely defying gravity

Working over at Burnham Beeches currently and we came across this dual decay on birch again today, this time with the added colonisation of Daedaleopsis confragosa thrown in for good measure.

Again at Burnham Beeches....

Brown rot and white rot at two ends of the same short beech wood volume. Fomitopsis pinicola (red banded polypore) and Pannellus stiptica - (bitter oysterling)
