This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. The purpose of this report is to identify and characterize the fungal species that may potentially damage wood and decrease its market values. It focuses on the characterization of 40 different basidiomycetous fungi that were isolated form 12 different sites across British Columbia. Fungi were isolated from mountain pine beetle-infested lodgepole pine trees in green, red, and grey stages from each of the 12 sites.--Includes text from Government of Canada publications site and from document.
