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.
在中国西南地区，从 3 月到 7 月，在当地的野生蘑菇市场和华山松林里发现了一种与松属植物有关的新的蜜环菌物种，当地人认为它是一种美味佳肴。基于形态学和分子系统发育分析，这些采集物被描述为属于 Versicolores 亚属的蜜环蕈 songmaodan 新种。这里描述的新物种增加了中国目前已知的蜜环菌物种的数量到十个。R. songmaodan 与华山松建立了外生菌根的联系，这通过比较担子果和外生菌根根尖的 rDNA ITS 序列得到了证实。通过在温室研究中进行 R. songmaodan 与两种本地松种（华山松和云南松）之间的孢子接种，成功地进行了菌根合成。R. songmaodan 易于接种到松属植物上，而且其子实体的市场需求量很高，这使得 R. songmaodan 成为在中国西南地区进行栽培的一个很好的候选物种。
