Atropellis piniphila (Weir) Lohman and Cash is a fungus that causes perennial stem and branch cankers of lodgepole pine (Pinus contorta Dougl.). In locations where this disease is prevalent, most or all host trees may become infected and multiple stem and branch infections are common. The disease reduces the value of trees for lumber, or pulp and many countries prohibit its importation in lumber.
This leaflet describes A. piniphila, one of four North American species of the genus which cause disease in pines. The information provided is probably also applicable to A. pinicola Zeller and Goodding. Atropellis pinicola, which attacks western white pine (P. monticola Dougl.) and, occasionally, lodgepole pine, is the only other species of Atropellis found in B. C.
