    Description

    The translation elongation factor-1 alpha gene was used to examine the phylogenetic relationships among 30 previously characterized isolates representing ten North American Armillaria species: A. solidipes (=A. ostoyae), A. gemina, A. calvescens, A. sinapina, A. mellea, A. gallica, A. nabsnona, North American biological species X, A. cepistipes, and A. tabescens. The phylogenetic relationships revealed clear separation of all ten North American Armillaria species, with the exception of one A. gallica isolate that perhaps represents an unnamed cryptic species. These results indicate that the elongation factor-1 alpha gene could potentially serve as a diagnostic tool for distinguishing among currently recognized North American biological species of Armillaria.
