Dual Decay

[David Humphries]

Ash with the dual decay of a long time colonisation with Perenniporia fraxinea and more recent Ganoderma australe colonisation.

Both have led to white rot decay which has consumed the lignin.

 

 

 

 

 

Psuedosclerotial plates separating the various colonies of the two fungal species and ants making the most of the decay by mining the altered wood volumes to create a maze of ant habitat.

Did you drill this tree David? Surprised it wasn't left as a habitat stick.

Yes Jake, been drilled a number of times over the last 5 years or so.

 

As you probably know, standing Habitat sticks are our usual default position but as we learn more and more about specific decay types and their interaction with specific tree species we have learnt that Perinniporia and ash does not 'stand' the test of too long a time.

Some of the upper wood volumes decayed by Inonotus hispidus have been resurrected in an adjacent tree to continue the habitat cycle.

I saw the video. Very impressive I must say. Unfortunately the video of the Ash management is not available to me. I'll try on the computer later.

Colonisation of two white rot fungi on the compression side of this sizeable London plane

 

 

 

Ganoderma resinaceum

 

 

 

 

Perenniporia fraxinea

 

 

 

The Resistograph shows that the buttresses either side of the fruit body's are sound but the heart is dysfunctional.

Are you correlating the pronounced buttressing to reaction to the fungal infection?

Taking it as read that fungal pathogens in the same sector of a tree willl normally ward off infections by other fungi, what would be interesting would be whether australe and resinaceum are so genetically similar that can have some form of co-existence in the same host.
