In this study, eight species of are recognized from Europe: , aff. 1, , cf, , . cf. , , and . Different candidates for the application of the name are evaluated and the best fit to the description is selected; lecto- and epitypes are chosen to fix the name. and are also epitypified and a new species, , is described. The infrageneric classification is revised and a new subgenus and three new sections, , and are introduced. The former sections and are elevated to subgeneric level. Comparison of the ITS regions (nuc rDNA ITS1-5.8S-ITS2) of all species studied shows that there is a minimum interspecific difference of 1.5 %, with the exception of the two species belonging to sect. which differ by a minimum of 0.9 %. Ecological specimen data indicate that species of form basidiomes under members of , with a general preference for species of . Five European species have been recorded under , while and have also been recorded as tree associates, although the detailed nutritional relationships of the genus, involving other suilloid fungi in particular, have yet to be fully clarified.
在本研究中，从欧洲识别出8个物种： 、近 1、 、近似 、 、近似 、 以及 。对该名称应用的不同候选物种进行了评估，并选择了最符合描述的物种；选定了主模式标本和后选模式标本以确定该名称。对 和 也选定了后选模式标本，并描述了一个新物种 。对属下分类进行了修订，引入了一个新亚属 和三个新组，即 、 和 。原有的 和 组提升到亚属级别。对所有研究物种的ITS区域（核糖体DNA ITS1 - 5.8S - ITS2）进行比较表明，除了属于 组的两个物种之间的最小种间差异为0.9%外，其他物种的种间最小差异为1.5%。生态标本数据表明， 属的物种在 属成员下形成担子果，一般更倾向于 属的物种。在 属记录到5个欧洲物种，但 属和 属也被记录为与树木共生，不过该属详细的营养关系，特别是与其他牛肝菌科真菌的关系，尚未完全阐明。
