The mourning wood is a legendary dark tree told of in ghost stories. Legend goes that if you stay the night in shadewood, a swampy forest dangerously close to the jungle, then it comes and eats you. It is a dark purple tree with a chiseled face like a jack-o-lantern and can use it's roots to walk like a spider. Supposedly, it used to be a noose tree, where people hung criminals. But one criminal, named Laughing Jack, placed a curse on the tree. As he died, goes the legend, the tree burst into flames, and now wanders the world, hunting for slenderman (no one knows quite why).
