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.

DERMEK A. (1968): A contribution toward a mycoflora of the Boletaceae of Záhorská nížina and the environs of Bratislava (tab. 68).  Česká Mykologie 22(2): 106-111   (published: 1968)
  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.

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.

KOTLABA F. (1990): X. Congress of European Mycologists, Estonia 1989.  Česká Mykologie 44(2): 119-125   (published: 22nd June, 1990)

KLÁN J., ŘANDA Z., BENADA J., HORYNA J. (1988): Investigation of non-radioactive Rb, Cs, and radiocaesium in higher fungi.  Česká Mykologie 42(3): 158-169   (published: 12th August, 1988)
  abstract   The concentration factors for non-radioactive Rb, Cs, and radiocaesium in the fruit bodies of mushrooms were determined. The difference between the concentration factors of non-radioactive and radioactive Cs from the last fallout was one order of magnitude. No significant differences were found between the concentration factors of stable Rb and Cs for mushrooms and vascular plants. The highest accumulation of radiocaesium was observed in Boletus spp., Laccaria spp., Paxillus involutus, Cortinarius armillatus, and Lactarius rufus. The contribution of older weapon-test fallout and the more recent 1986 Chernobyl fallout could be differentiated by isotopic ratio. The radiation dose from consumption of 10 kg fresh mushrooms did not exceed 20% of the dose from natural background radiation in Czechoslovakia.

ŠEBEK S. (1979): Zur Pilzflora des Hügels „Semická hůrka“ (Kreis Nymburk, Bez. Mittelböhmen).  Česká Mykologie 33(3): 159-169   (published: 1979)
  abstract   The author provides an overview of the fungal flora of the hill “Semická hůrka” (District of Nymburk) in central Polabí, covered by subxerophilous oak forest with fragments of the Querco-Carpinetum bohemicum community. On the southern slope, communities of the order Prunetalia mix with substitute communities from the Cirsio-Brachypodion pinnati alliance. The location is a notable site of thermophilic fungi in central Polabí. A proposal for protection of this site is attached.

PILÁT A. (1973): Duae species generis Leccinum S. F. Gray regionum Europaee borealium incolae.  Česká Mykologie 27(1): 9-10   (published: 1973)
  abstract   Photographs and descriptions of two species of the genus Leccinum collected in northern Finland near Kevo are presented: Leccinum percandidum and Leccinum oxydabile. L. percandidum is closely related to L. testaceoscabrum, differing mainly in having a white pileus and stipe. The distribution, habitat, and morphological features are detailed. L. oxydabile belongs to the group of Leccinum griseum and differs in color changes of the flesh. Both species are associated with Betula.
