Can anyone help me identify

Can anyone help me identify this? Found by a retired farmer who would be fascinated to know what this is or why it has grown?

Some sort of gall?

No idea really - how big is it? From the envelope I'd guess several cm across? Do you know what sort of twig it was on?

Galls..

I would go with it being a plant gall as well. A gall is the plants reaction to an organism such as a parasitic fly, a virus, a bacterium. More information about them can be found on the British Plant Gall Society website http://www.british-galls.org.uk/

Gall-like growth on hazel

This seems most likely to be caused by a virus, it's certainly spectacular if it is as big as a cricket ball. Another possibility is that it is a reaction to damage, or to chemicals being used in the vicinity of the plant.

If any more specimens can be collected I would appreciate being sent one to have a look at please.
