A new Rhizopogon species associated with Pinus was discovered at local wild mushroom markets and Pinus armandii forests from March to July in Southwest China where it is considered a delicacy. Based on morphological and molecular phylogenetic analyses, the collections were described as Rhizopogon songmaodan sp. nov. belonging to the subgenus Versicolores. The new species described here increases the current number of Rhizopogon species known in China to ten. R. songmaodan establishes ectomycorrhizal associations with P. armandii which was confirmed by comparing rDNA ITS sequences from basidiomata and ectomycorrhizal root tips. Mycorrhizal synthesis via spore inoculation between R. songmaodan and two native pine species, Pinus armandii and P. yunnanensis was successfully carried out in a greenhouse study. The ease of R. songmaodan inoculation onto pine species, and the high market demand of its sporocarps, could make R. songmaodan a good candidate for cultivation in Southwest China.
