ash tree fungus ID

[KWOOLD]

This fungus is growing on the base of an ash tree, which is about 1m diam x30metres tall. It is adjacent to a walkway and a house. The fungus is quite hard and the larger section is about 1 ft across. Could anyone help me to identify it, and whether it has implications on the stability of the tree? I wonder whether it could be Perreniporia fraxinea? The tree has been in leaf during the summer.

That'd be my guess mate....It can be distinguished from Rigidiporous by way of the tubes layers ( inside the FB)

Check out Perenni in the books, online or with the fungal directory here !

I would go with perenniporia fraxinea too, it apart from the tube layer can also be differentiated from rigidiporus by the rot, perenniporia being a white rot, with Rigidiporus being a friable brown rot.

Thanks for your help. If I am to cut a section, what would be the particular differences that I should look for to differentiate between the two?

If you have a look on here it is quite comprehensive Arbtalk.co.uk | Discussion Forum for Arborists Fungi Directory

Thanks. Have looked at that is very informative. Now for the dissection!!!
