ŠUTARA J. (2008): Xerocomus s. l. in the light of the present state of knowledge.   [Boletaceae, Xerocomus, Xerocomellus, Hemileccinum, generic taxonomy, anatomy, histology]  Czech Mycology 60(1): 29-62   (published: 4th July, 2008)
  abstract   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.

SINGER R., KUTHAN J. (1976): Notes on Boletes.  Česká Mykologie 30(3-4): 143-155   (published: 1976)
  abstract   Mycorrhizal associations of boletes and Gomphidiaceae in the High Tatra Mountains are discussed, focusing on those linked with Pinus mugo and P. cembra. Taxonomic and morphological notes on Boletus erythropus ssp. erythropus and ssp. discolor are given, along with description of a new species, Xerocomus flavus.
