A total of 768 two-year-old lodgepole pine (Pinuscontorta var. latifolia Engelm.) seedlings were transplanted into four different soils, having different capabilities for supporting lodgepole pine growth. Thirty days later, they were inoculated with either of two isolates of North American Biological Species I (Armillariaostoyae (Romag.) Herink) of Armillaria. Log–linear analysis indicated that soil type had a significant effect on inoculum viability, rhizomorph production, frequency of seedling infection, and the likelihood of tree death following infection.
