Nice set i came across in Brighton yesterday on a young syacamore.

Is it a syc? Bark doesn't look quite right.

Sean,

Did you look up ? As my photo's show, Polyporus squamosus can be quite detrimental to trees, especially to Fraxinus, Acer and Ulmus, and trigger "emergency reproduction" of both the tree (lots of seeds, which are for the greater part sterile) and the mycelium (unusual big and/or numerous fruitbodies), announcing the tree is soon to die (and fall). And P. squamosus can be alarmingly dangerous, when it is overlooked because of it fruiting at great hight from large old pruning wounds of Acer or Ulmus.

that ash in the middle is riddled with ash canker too though, and certian the polypore came long after the cankers and cambium dysfunction.

Tony,

Which type of ash cancer do you mean, cancer caused by the ascomycete Nectria galligena or by the bacteria Pseudomonas savastanoi pv. fraxini ? If you mean the first fungal one, which I assume, sure it did, because the spores of P. squamosus infect dead wood in open (pruning) wounds first and then from the infected wound the hyphae infiltrate the cambium and the mycelium becomes (necrotrophic) parasitic. And what I meant to show as an example of "body language" of both the tree and the fungus (or fungi), is the co-existence of emergency reproduction with both "partners" in the deadly bond, the latter one fruiting from the cambium on the trunk and from the base of the tree, a not to be misunderstood signal of the possible danger of breaking or falling of the tree.

Im not sure I completely understand but I said bacterial canker so I was wrong anyway!

 

again!
