Eutypella parasitica R.W. Davidson & R.C. Lorenz 1938
fungi species in the diatrypaceae family
Eutypella canker is a plant disease caused by the fungal pathogen Eutypella parasitica. This disease is capable of infecting many species of maple trees and produces a large, distinguishable canker on the main trunk of the tree. Infection and spread of the disease is accomplished with the release of ascospores from perithecia. Therefore, the best way to manage the Eutypella canker is to remove trees that have been infected. If infected, it can decrease the quality of wood cut for lumber and can thus have a negative economic impact.

Grosmannia clavigera (Rob.-Jeffr. & R.W. Davidson) Zipfel, Z.W. de Beer & M.J. Wingf. 2006
fungi species in the ophiostomataceae family
Grosmannia clavigera is a species of sac fungus that causes blue stain in wood. It spreads to lodgepole pine, ponderosa pine, Douglas-fir, and whitebark pine trees from the body and a special structure in the heads of mountain pine beetles. The blue stain fungus has evolved a relationship with mountain pine beetles that allow them to travel from tree to tree on a special structure in the beetle's heads and stops the tree from producing resin to pitch out or kill the beetle, encouraging the pine beetle infestation occurring all along the Rocky Mountains from Mexico into Canada. The beetles are
