Try to scratch it off. IF it comes off easily, inspect the thing and
on the underside you may see parts of the insect called scale. You
can treat that with insecticidal soap. Just go over to Rohde's and
bring some of what's on your tree in a tightly closed jar or bag and
make sure scale is what you have.

Hello,

I've got a 3 year-old Live Oak....in the North Dallas area.....and in
the last month..a sort of bulbous, black, growth has begun to appear.
Can anyone identify what this might be? My neighbor (whom may be a bit
paranoid) was thinking "Sudden Oak Death"..but I'm under impression
that that has not really hit my area....

I've posted some photos...

Any help would be appreciated...

Thanks,
