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,

My first instinct was wasp galls, but looking at the photos, I think
not. Perhaps some kind of scale insect?

Pry a couple off and see if there are legs and such underneath.

If so, treat with dormant oil/horticultural oil/Volck oil.
