Inonotus tomentosus is a fungal pathogen of commercially valuable tree species in British Columbia and one of the most important biotic disturbance agents in sub-boreal and boreal forests in Canada. Although ubiquitous across North America, little is known about mode of infection and relative roles of basidiospores and root contact in disease spread. An investigation into the diversity of genotypes of I. tomentosus will help to determine whether infection is due to spread by root contact, by basidiospores, or a combination of the two and if forest management affects the mode of disease spread. This information is essential to properly manage the disease and to understand the potential impact on timber supply from second growth stands.
