I have a tree in my back yard that has become infested with some nasty bug. There are patches of raised bumps around the trunk that can peel right off with almost no effort. The wood below is rotting and very wet. I occasionally see really gross wiggling white and black spotted larvas that slide back into the wood of the tree. One time, I saw something that looked like an ant when I peeled off a bump. The bumps go both ways, under the bark as well. When I peel them off, I saw rounded bumps underneath, often with sharp points that didn't look like wood at the ends - it was a different color (darker, almost tan). The bumpy areas on the trunk are slowly spreading, and the bark on many of the main brances of the tree has been peeling off.
Any thoughts?

thoughts.... doesn't sound good, but we'll need a better description. Let's start with type of tree. Can you accurately identify it? Are these bumps part of the bark, or something growing on it?

I can't tell for sure. It looks like a species of willow. The bumps almost look like they are pimples that are being caused by the growth of the larva in the wood.
I've published some pictures on the web. Here are some links of:

Very strange, At first I though they were burls. But you say the detach from the trunk?
This growth is it woody? or spongy like a mushroom?

The growth is woody, and the points are actually relatively sharp. The odd thing is that the wood underneath when I remove the bark (with the knots underneath) is very moist. It almost seems like whatever is growing inside the wood is displacing it, and that is what is causing the bumps and the bark to slowly come off around the trunk.
Any thoughts?
