Cypress Tree Problem in Indiana

Any idea what's going on with these trees? Those little white nodes are about the size of a bag worm. They start small, get to the size of a bag worm and turn purple. Now they are getting new ones for the second time this summer. They are not bag worms. I know what those are and have treated for them before. It is only on the cypress and at the end of a stem. They are solid and juicy with no bug I can tell of inside. The japanese beetles were eating them before.

Stem canker? Take a branch to your local Cooperative Extension Service for diagnosis.

Thanks for the suggestion but I don't think that's it.

The greenery on mine doesn't turn brown and there are not specific brown splotches. There are just little white balls on the end of the branches like kids have decorated the whole tree with cotton balls or something.

In any event the county ag agent has some samples now and he couldn't find any thing in any of his books either. He's looking at it with a microscope and checking more references I suppose. He said he would let me know when he figures it out but he's thinking some kind of a bug or mite for right now until he knows better.

That was one of the extention agents first guesses but he decided the little bulbs didn't look quite right for it.

After looking at these http://bugguide.net/index.php?q=search&keys=spittle I'm pretty sure those are not the problem.

The white balls on my trees are pretty tuff if you try to squeeze them or cut them and not at all like spit or foam and there is no bug big enough for me to see it.
