The relationship between the occurrence of sporophores of the root rot pathogen Inonotus tomentosus (Basidiomycota, Hymenochaetaceae) and disease symptoms was studied in a white spruce plantation (Picea glauca) in Canada over a period of 14 years. Numbers of sporophore clusters (three or more sporophores within 1 m of each other) were well correlated with numbers of infected living or dead trees (r = 0.64–0.86, p = 0.000–0.003). Infected trees may have sporophores around them before external symptoms of disease occur on the tree. As numbers of dead trees increased, the numbers of infected living trees remained constant, indicating increased infection within the stand. However, the number of sporophores varied considerably between the years. The diagnostic value of sporophores for tomentosus root rot is discussed.
