ZOTTI M., PAUTASSO M. (2013): Macrofungi in Mediterranean Quercus ilex woodlands: relations to vegetation structure, ecological gradients and higher-taxon approach.   [conservation biology, ectomycorrhiza (ECM), fungal diversity, multivariate analysis]  Czech Mycology 65(2): 193-218   (published: 20th December, 2013)
  abstract   Few studies have investigated the relationships between mycodiversity and plant communities in Quercus ilex (holm oak) woodlands. These are unique ecosystems in the Mediterranean basin of high mycological importance. The macrofungi of Q. ilex forests in Liguria, North-Western Italy, were studied: 246 species were observed in 15 permanent plots over four years. Some species were identified as typical of holm oak woodlands, e.g. Hygrophorus russula, Leccinellum lepidum, and Lactarius atlanticus.Correspondence analysis (CA) showed that the main ecological gradients shaping the fungal and plant communities are driven by soil pH and climatic factors. The CA confirms that the minimum sampling area for macrofungi is larger than for plant communities and that aggregation of multiple plots is suitable for data analysis. The data suggest that the higher-taxon approach can be successfully applied also to Q. ilex macrofungi, not only for total species and genus richness, but also within abundance classes. Further investigations are required to better characterise the mycodiversity of Mediterranean holm oak woodlands in relation to human impacts over various scales to plan effective conservation strategies.

JANDA V., KŘÍŽ M., REJSEK J. (2013): First records of Xerocomus chrysonemus (Boletaceae) in the Czech Republic.   [Xerocomus chrysonemus, Boletaceae, description, ecology, Czech Republic]  Czech Mycology 65(2): 157-169   (published: 20th December, 2013)
  abstract   The paper details the first collections of Xerocomus chrysonemus in the Czech Republic. The authors present a macro- and microscopic description of this species based on the study of material collected at five different localities. Characters distinguishing X. chrysonemus from related species of the genus Xerocomus s. str. (X. ferrugineus, X. subtomentosus, and X. silwoodensis) are discussed. The Latin name X. chrysonemus is a combination of the words ‘chryso’ = golden and ‘nema’ = mycelium, which very accurately describes the characteristic feature of this species, the golden yellow mycelium at the base of stipe.

KUNCA V. (2012): Boletus moravicus - ecological conditions of new localities in Slovakia.   [red-listed species, ecology, pH values]  Czech Mycology 64(2): 165-174   (published: 7th December, 2012)
  abstract   Ecological conditions of four new localities where Boletus moravicus occurs are described. Oaks prevail in the studied forest communities. Our measurements of soil pH values showed that the localities, all on volcanic bedrock, have very acidic to mildly acidic soils. We can confirm the published fructification from July to October. Finds in Slovakia were recorded from altitudes of 210 m to 518 m a.s.l.mainly from Carpinion betuli forest communities.

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.

ŠUTARA J. (1989): The delimitation of the genus Leccinum.  Česká Mykologie 43(1): 1-12   (published: 6th February, 1989)
  abstract   The International Botanical Congress in Berlin 1987 accepted a change of Art. 63 of the nomenclatural rules. According to the new, changed wording of Art. 63 the generic name Leccinum is now legitimate. This fact is respected by the author of this paper and therefore Leccinum is here used as a correct name for the genus in question. The genus Leccinum S. F. Gray (Boletaceae) is distinguished from the other boletes by a peculiar arrangement of the surface tissues of the stipe. This peculiar type of the stipe covering is here described. The differences between the stipe coverings of the genera Leccinum and Boletus Fries are discussed in detail. A list of the examined material with notes on some species is appended. The following new combinations are proposed: Leccinum depilatum, Leccinum fragrans, Leccinum luteoporum, Leccinum niveum, Leccinum pseudoscabrum and Leccinum rufescens.

  abstract   The author lists Boletaceae species collected in 1963–1967 in the Záhorská lowlands and around Bratislava, and describes the rare species Xerocomus armeniacus (Quél.) Quél.
