Tony Croft aka hamadryad I have photographic documentation of A.mellea on ash lasting several years and thus far it appears to be able to deal with it for a number of years how long is the question. 23-11-12
David Humphries Were you able to confirm that the species was the agressive A. mellea, and not one of the other Armillaria species?

joki23 in the article linked at the bottom of the page "honey fungus - friend or foe" it says that ash is resistant to the fungus. i found an ash today in a woodland setting with what appeared to be dead fruiting bodies of A. mellea at the base of the tree. the surrounding bark was dead and dieing and would come off when touched. as the article was published in 2001 is it a little out dated or does it still stand that ash is mostly resistant to A. mellea but i just stumbled across an unlucky one that has become infected by the fungus? 22-11-12
