Saw this on a tree (beech I think) on a walk today and thought it was interesting.

Thats a bulge all right . Good spot . Some one with a greater knowledge than me will be along to give a cause and a reason . Dave Humphreys possibly ??

Looks like a bloody big sphaeroblast!

[Amelanchier]

Looks like a stem gall - Agrobacterium tumefaciens

I don't think this would be a spheroblast Dan.

 

I understand that Speroblasts in essence, are meristematic cell disorders where the process of cell division to produce a bud does not complete and the miss formed bud becomes included with every years annual growth.

 

Usually no bigger than a duck egg as they tend to eventually detach from the stem probably due to weight and abscission.

 

like in the shot of this oak below.

 

 

 

I think the growth (burr) in the original post may be scar tissue that has formed at a trauma and is mal-formed grain in the annual layed down wood

 

........or what Tony said
