Phylogenetic relationships among biological species of Armillaria from China

摘要: Fourteen Chinese Biological Species (CBS) of Armillaria were previously identified in a collection isolates. CBS C, F, G, H, J, L, N and O remained unnamed, while the remaining isolates included A. borealis, cepistipes, gallica, mellea, sinapina tabescens. F was suggested to represent singula based on basidiocarp morphology. In this study, phylogenetic relationships between those from other parts world determined DNA sequence data. Results study suggest that might not singula, monadelpha (a name applied North American form tabescens by some authors) should be treated as single species. Four main lineages, referred ostoyae, mellea clusters, trees. The unnamed biological species grouped within “A. gallica cluster” phylogenetically closely related. results contribute our current understanding systematics South East Asia where these fungi are relatively poorly known.
