Here's one from down-under - Canker rot fungi Phellinus robustus

[Cassian Humphreys]

P. robustus very common in South East Queensland AUS, makes good habitat hollows for green tree snakes. Never seen a tree failure in association with this one. The host trees are generally Gums - Eucalyptus spp & Corymbia spp.

 

 

 

 

 

The sections of gum are Forest Red - E. tereticornis, the cross section slide is of Ulmus spp from the US...

Hello Cassian

 

You probably know P. robustus is realtive rare here in the UK.

 

So not a lot known about the associated decay and probably (as you suggest) few examples of associated failure.

 

Do you find it hosted on Quercus as well as the gums that you list?

 

Here its predominantly on oak but also noted on beech, ash, elm & sweet chestnut

Hi David, I did not know if she was present in Britain, I only know of two Oak trees in S.E. Qld old enough to host fungi, so no examples on Oak (maybe in Southern Australia). Having covered tree populations (corridors) doing VTA on HV power lines from Central West Brisbane to Wide Bay (and across the dividing range) I have seen this fungi commonly.

 

Also an Oz native Phellinus lamaensis (another white canker/pocket rot) reported to be on rainforest species, though likewise I have seen it commonly on gum populations on the Energex network.

We have very few publications on decay fungi and virtually no research (anymore) so are very limited to cover this topic.

The Queensland Mycological Society is strong on saprophytic/mycorrhizal fungi not so on parasitic.
