Perenniporia fraxinea?

[Lloyd Jerrey]

Good evening,

 

Is my diagnosis of Perenniporia fraxinea correct? Or am I mistaken?

 

Quite hard and rubbery to touch and spread around 1/3 of the base of this Ash. I also believe I spotted Armillaria previously in the cavity but no 'shrooms' at the moment.

 

Not the best pics I'm afraid

 

 

 

Teaching myself through books so apologies if it seems very basic.

 

Any help much appreciated

Certainly looks a likely candidate. ..

Thanks Sloth

 

Any idea what the fungus would be doing to the buttress roots?

 

Been watching it a couple of years and last 6 months about 4-5 new small ones have developed very fast as previously it was just one large one?

 

Thanks

It could be white rotting them, or more likely the wood further in the centre. Alternatively it could be Rigidoporous ulmarus brown rotting the stem base. Need a slice showing the flesh and tube/pore layers to differentiate the two-they'll look a similar colour if P fraxinea.

Either way it doesn't bode well on an ash. Obviously tree form and location/targets etc will steer management decisions.

Will take a slice next time I'm there.

 

Booked in to fell in September sadly, been watching it a couple of years and base seems to have got worse with cracks forming on the backside of the tree and customer agreed to remove.

 

Re plant with something more colourful 👍
