Tricholoma may be a paraphyletic genus two. The collections identified as T. caligatum is a mixture. Some parts of them from France are members of T. matsutake, the other parts from North America are closed to T. bakamatsutake and T. fulvocastaneum. Tricholoma robustum and T. focale form a clade which is obviously a sister group of the stirp Subannulate. The stirp Caligata was defined as a group mainly on the basis of the predominant veil. But from the result of molecular systematic analysis, the presence of veil is not a stable character in the matsutake group. Species having symbiosis with conifers and broad leaf tree are all transformed from those whose host specificity is not strict. The phylogenetic tree based on ITS sequences resembled the tree of NJ algorithm based on cladistic coding. In the phylogenetic tree based on morphylogical characters, T. zangii and T. bakamatsutake form a clade, but it is the result of convergent evolution as suggested by molecular analyses. The distribution area of the matsutake group can be divided into six regions: middle and northern Europe region, Mediterranean region, Hengduan Mount.— Southeastern Tibet region, Northeastern China—Japan—Far-east Russia region, the Atlantic—North America region and the Rocky Mountain region. The abundance center of the matsutake group are Hengduan Mount.—Southeastern Tibet region and the Rocky Mountain region. Hengduan Mount.

松口蘑群的分子系统学研究得出的结果有:由于粗壮口蘑和羽衣口蘑明显和亚环族(Tricholoma,section subannulate)的种类是来自同一个谱系,和其它松口蘑群的种不具有最近共同祖先,因此松口蘑群是一个多系群;松口蘑群和口蘑属其他种类的亲缘关系比和蜜环菌属更接近;梭柄松苞菇和松口蘑群的差距明显小于油黄口蘑(T.flavovirens)和棕灰口蘑;口蘑属是一个多系群;鉴定为欧洲口蘑的标本明显不是一个单系群,其中一部分是松口蘑,另一部分和黄褐口蘑及傻松口蘑(T.bakamatsutake)比较接近;划分松口蘑群的标准是菌环的存在,但从分子系统学的结果来看,菌环的存在与否并非是一个很稳定的性状;和针叶树专性共生及和阔叶树专性共生均由寄主专化性不强的种类转化而来;在形态学系统发育树上青冈口蘑和傻松口蘑被聚为一个分枝,分子系统学的研究结果表明,这是趋同进化的结果;用支序方法编码作出的NJ树的结果更接近ITS序列的结果。
