Looks like Southern Hackberry with nipple gall.

I've got some pictures of a tree in our backyard posted here
http://michaelelliott3.tripod.com/tree/tree.html
Thanks to anyone who can shed some light on this; I'm a complete
tree
non-expert. I don't even know what species it is. At the end of
last
summer, we noticed some strange growths or tumors on the ends of
the
twigs. I recall that I broke a couple of them open, and there
was a
liquid inside which was bluish in color. This year, I see these
small
greenish balls forming along the green shoots. The
abnormal-appearing
ones seem to be present at the junction between the leaves and
the
twig. There are some smaller ones that also look like normal
fruit/seeds from the tree (they are on their own individual
stalks).
There are also some growths on many of the leaves. I've included
close-ups of the front and back of the leaves. The lesions
penetrate
through the leaf. I've looked on the 'net a bit, and the only
thing
that I can find is "black knot gall" which sounds similar.
If anyone can write back to me at (subject:
trees)
and let me know, I'd appreciate it. We're in mid-Oklahoma, if
that
helps the species/disease determination. The main info I'm
looking for
is:
1) what species of tree is this?
2) do you know what is going on? For all I know, these are
normal
findings
3) Any ideas about what to do about it?
Thanks! Michael
