Sick Ash

[Fungus]

... armillaria ... look at the butresses and new tissues at the base. got the body language of decay all over it.

 

Tony,

Agreed, but would you also attribute the vertical split with necrosis at the margins to Armillaria ? I would sooner expect this to be caused by either the ascomycete Nectria galligena, or by the bacteria Pseudomonas savastanoi pv. fraxini.

and lets not rule out A. mesenterica, ash is a fave host, but the canker is in my mind hispidus for the most part, but agree with you that its complications are obviously not entirely Hispidus related:thumbup1:

But with A. mesenterica, wouldn't you have found some fresh, dried out or revived fruiting of it inside the wound ?

Those images you saw that I posted regarding symptoms of A. mesenterica with fruits are a rare bunch, often you dont see the fruits, and thanks to your education of my eye I realise this is possibly partly down to the fact that friuting is often a means of escape. mesenterica has little need to escape in most colonisations as it tends to veteranise rather than kill its host, also it fruits in clumps and these when dry break up fall off and degrade with very little evidence. I am working on the funds for a lab at the bottom of the garden, one day I will force fruiting of wood samples taken directly from the body languages. I find fruits in association of course, often enough to have tied a great deal to this discrete little fungi, but its a sneaky dog, and often it will be a very small fruiting that is perishing on the tree before we find it.

 

Sometimes all that is left is a thin black sheet of totaly dessicated fruit body, almost impossible to distinguish from bits of dessicated Exidias. This fungi fascinates me more than any other at the moment, its not certain for sure, I must do much work in order to prove my thoughts on it.

 

one thing I should say here is I have come to the conclusion that you may well be right on the plating being armillaria, I think maybe the mesenterica going top down, (on beech) results in a dying root associated with the branch colonised, the armillaria finds the root and tracks up and meets the messenterica, however what occurs at this interaction is a new question for me.
