Tuber aestivum? (I think)

Not sure about this one, found growing at the base of a sycamore tree, half in the ground half out, clearly attached to the tree stump by a small part of the tuber..... you can see this in the picture.

Smells mushroomy, slightly sweet, any ideas please...

Sorry Stew - This looks interesting, but not sure this is T.aestivum. I would expect aestivum to be much more 'warty' on the outer surface - like this one

and more marbled, and slightly darker yellow / brown in the cross section.

Having said that, I'm fresh out of suggestions - not much experience with tubers...

Hi
On the photo of the speimen cut in two you can see the perithecia around the inside edge of the fruitbody. This is a Xylaria species. Most likely Xylaria polymorpha
