Abstract: Russuloid ectomycorrhizae on 1-2 yearsold seedlings of Pinus yunnanensis collected from the central Yunnan, China were investigated. Six morphotypes were recognized by macro and anatomicalmorphological approaches as well as molecular analyses. The six morphotypes were confirmed to represent six phylotypes by matching rDNA ITS sequences. The fungal partners in the six morphophylotypes are those closely related with Russula livescens, Rvioleipes ,Rdensifolia ,Rnigricans ,Rsanguinea and Rnauseosa respectively. The correlation between the morphology of mantles and cystidia and the phylogenetic clades is further supported in our work. The framework, in which this report is included, shows that russuloid mycorrhizae are one of the most dominant representative ectomycorrhizae formed on 1-2 years seedlings of Pinus yunnanensis.
