ABSTRACT:      Pseudotsuga menziesii (Mirb.) Franco, also known as Oregon pine, is a conifer indigenous of North America (Vega et al., 1998). At present, it is considered a species interesting for reforesting due to the good quality of its wood. In Galician forests, P. menziesii has been affected by several diseases, caused by fungus, among them the white root rot caused by Armillaria mellea. Armillaria genus comprises species with different pathogenic behaviour. Recently, with the use of PCR-RFLP techniques the species: A. mellea and A. gallica were indentified. An assay on P. menziensii was performed to evaluate the pathogenicity of these species. In this work, an isolate of the species A. ostoyae was also used since it is considered the most pathogenic species in conifers.
