对Xerocomus s. L.特别是该属与牛肝菌属的界限还很不清楚，而且有争议。作者在研究牛肝菌科欧洲种的过程中，得出了一个结论：宽概念的Xerocomus是几个种类群的异质混合物。这些群体因解剖学特征和其他一些特征而彼此分离。最近的分子生物学研究表明，Xerocomus s. L.不是一个单系群。与这些事实相一致，Xerocomus s的欧洲物种。L.本文将其解剖学研究分为以下几个较明确的属：Xerocomus s. str.，Phylloporus，Xerocomellus gen. nov.，Hemileccinum gen. nov.和拟牛肝菌（Pseudoboletus）。Boletus badius和Boletus moravicus也经常被视为Xerocomus的种，目前保留在Boletus属中。Xerocomus s之间的差异。str.，对其中的Phylloporus、Xerocomellus、Hemileccinum、Pseudoboletus和Boletus（与该属有亲缘关系）进行了详细的讨论。提出了两个新属，Xerocomellus和Hemileccinum，以及必要的新的种名组合。
The definition of the generic limits of Xerocomus s. l. and particularly the delimitation of this genus from Boletus is very unclear and controversial. During his study of European species of the Boletaceae, the author has come to the conclusion that Xerocomus in a wide concept is a heterogeneous mixture of several groups of species. These groups are separated from each other by different anatomical and some other characters. Also recent molecular studies show that Xerocomus s. l. is not a monophyletic group. In agreement with these facts, the European species of Xerocomus s. l. whose anatomy was studied by the present author are here classified into the following, more distinctly delimited genera: Xerocomus s. str., Phylloporus, Xerocomellus gen. nov., Hemileccinum gen. nov. and Pseudoboletus. Boletus badius and Boletus moravicus, also often treated as species of Xerocomus, are retained for the present in the genus Boletus. The differences between Xerocomus s. str., Phylloporus, Xerocomellus, Hemileccinum, Pseudoboletus and Boletus (which is related to this group of genera) are discussed in detail. Two new genera, Xerocomellus and Hemileccinum, and necessary new combinations of species names are proposed.
