I have small brown spots on my oak trees...not sure what that is, but they
seem to be doing quite well, regardless of the spots. The only thing I can
think of is the "tent-worm", but that wouldn't be on the trunk that I know
of. We have tentworms in Michigan, and they hang off of the branches (leafy
ends)...Definitely something to do some research on.
