Gromannia clavier, also known as blue stain fungus for the stain it leaves in the wood of infected trees, is carried to the host trees by bark beetles. It weakens the tree's natural defense system, which allows bark beetles to feed and reproduce in the tree bark. A successful beetle fungus attack ultimately causes tree death.
