JANDA V., KŘÍŽ M., KOLAŘÍK M. (2019): Butyriboletus regius and Butyriboletus fechtneri: typification of two well-known species   [lectotype, epitype, nomenclature, taxonomy, Czech Republic]  Czech Mycology 71(1): 1-32   (published: 2nd January, 2019)
  abstract   The paper deals with type material of two species of the genus Butyriboletus, which were described from the Czech Republic, originally as Boletus regius (Krombholz 1983) and Boletus fechtneri (Velenovský 1922). For both species lectotypes are designated, for B. fechtneri also an epitype. The authors present macro- and microscopic descriptions of these species based on the study of rich material including collections from the area of the type localities. Characters distinguishing both species from similar taxa are discussed.

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.

ŠUTARA J. (2005): Central European genera of the Boletaceae and Suillaceae, with notes on their anatomical characters.   [Boletaceae, Suillaceae, generic taxonomy, anatomical characters]  Czech Mycology 57(1-2): 1-50   (published: 31st August, 2005)
  abstract   A taxonomic survey of Central European genera of the familiesBoletaceae and Suillaceae with tubular hymenophores, including the lamellate Phylloporus, is presented. Questions concerning the delimitation of the bolete genera ar ediscussed. Descriptions and keys to the families and genera are based predominantly on anatomical characters of the carpophores. Attention is also paid to peripheral layers of stipe tissue, whose anatomical structur ehas not been sufficiently studied. The study of these layers, above all of the caulohymenium and the lateral stipestratum, can provide information important for a better understanding of relationships between taxonomic groups in these families. The presence (or absence) of the caulohymenium with spore-bearing caulobasidia on the stipe surface is here considered as a significant generic character of boletes. A new combination, Pseudoboletus astraeicola (Imazeki) Šutara, is proposed.

DECOCK C., RYVARDEN L. (2002): Two undescibed Microporellus species and notes on M. clemensiae, M. setigerus and M. subincarnatus.   [Africa, Amauroderma, Microporellus, Perenniporia, South America, taxonomy]  Czech Mycology 54(1-2): 19-30   (published: 3rd October, 2002)
  abstract   Microporellus brasiliensis sp. nov. and Microporellus ellipsosporus sp. nov. are described from Brazil and Senegal, respectively. Microporellus setigerus Corner and Microporellus subincamatus Corner are shown to be a synonyms of Amauroderma schomburgkii and Perenniporia stipitata, respectively.

DERMEK A., KUTHAN J., SINGER R. (1976): An interesting subspecies of Boletus erythropus (Fr. ex Fr.) Krombh. (With colored plate No. 89).  Česká Mykologie 30(1): 1-2   (published: 1st February, 1976)
  abstract   During two collecting trips in a thermophilous frondose wood "Zlodějský háj" near Starý Poddvorov in southern Moravia a find of an interesting Boletus of the group of Boletus erythropus (Fr. ex Fr.) Krombh. has been made. This fungus is described below by the authors as a new subspecies of the mentioned Boletus erythropus.

  abstract   The author provides a description, ecology, and phenology of Boletus aereus in Czechoslovakia and discusses its distribution. Six localities are mentioned. The paper also clarifies nomenclatural confusion with Boletus appendiculatus and discusses its taxonomic history.
