The Wood Sprite is a type of ghost from "The Family Tree", a short story from The Real Ghostbusters Magazine Winter 1991. One wood sprite was in an elm tree that was thought to be cut down. It scared the inspectors and attacked the trees owner. The Ghostbusters were called and were prepped to destroy the tree to coax it out, but were stopped by the owner. Instead, they disguised themselves as inspectors and tricked the wood sprite into thinking they would get the tree cut, then when the ghost came out, they blasted it with their proton beams and captured it.
