ŠUTARA J., SKÁLA E. (2007): Boletus marekii, a new species with truncate spores from the Boletus chrysenteron group. [Boletus marekii spec. nov., Boletus subgen. Xerocomus, Boletaceae, Czech Republic] Czech Mycology 59(1): 11-24 (published: 28th June, 2007)
abstract
Boletus marekii, a new species which was found in northwestern Bohemia (Czech Republic), is described. This species, belonging to the Boletus chrysenteron group (Boletus subgen. Xerocomus), is characterised mainly by its xerocomoid appearance, red-coloured, soon coarsely rimose-areolate pileus and smooth, truncate spores. Characters distinguishing Boletus marekii from other species of this group, e.g. Boletus armeniacus, Boletus rubellus, Boletus porosporus, Boletus fennicus, Boletus ripariellus and Boletus declivitatum, are discussed. A new combination, Boletus fennicus, is proposed.

abstract
A comprehensive overview of fungal species published from the Boubín primeval forest in the Šumava mountains is presented. The author compiled records from ca. 50 mycological excursions since 1906 and integrated them with modern taxonomy. This basic inventory serves as a foundation for future studies of fungal succession in this protected forest.
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.

(2000): Mycocoenological studies in Mediterranean forest ecosystems: calcicolous deciduous oak woods of central-southern Tuscany (Italy). [mycocoenology, calcicolous deciduous oak woods, Mediterranean] Czech Mycology 52(1): 1-16 (published: 21st January, 2000)
abstract
The results of mycocoenological studies carried out in calcicolous deciduous oak woods of central-southern Tuscany are reported. Comparison with there sults of studies in other for est ecosystems of the same area revealed exclusive differential species of deciduous oak woods and clarified the knowledge on mycocoenoses of central-southern Tuscany. The obtained in formation on individual species is also useful for understanding the relatively unexplored field of the ecology of macrofungi.
HOLEC J. (1994): The ultrastructure of the spore wall and ornamentation in the Xerocomus group of Boletus. [Xerocomus, Boletus, Strobilomyces, ultrastructure, transmission electron microscope, spore wall, ornamentation, taxonomy] Czech Mycology 47(3): 173-184 (published: 17th June, 1994)
abstract
The spore wall of five selected species of the Xerocomus group of Boletus was studied with a transmission electron microscope (TEM). The wall is composed of five layers in all the species studied: a very thin electron-dense outer layer 1 (ectosporium), a moderately electron-dense layer 2 (perisporium), a thick and amorphous electron-dense middle layer 3a (exosporium) that passes gradually into a thinner, granular or granular-fibrillar and moderately electron-dense layer *3b (episporium), and an almost electron-transparent layer 4 (endosporium). A smooth spore surface was found in Boletus pulverulentus and B. chrysenteron. A striate exosporium covered by the ectosporium and the perisporium was found in B. pruinatus, rough warts originating from a disrupted perisporium and ectosporium in B. parasiticus, and very fine warts composed of outgrowths of the ectosporium and part of the perisporium in B. subtomentosus. A species of an other group of the Boletales with conspicuous ornamentation (Strobilomyces strobilaceus) was examined as comparative material. The results of this TEM study are compared with SEM photographs of the spores of Xerocomus published by other authors, and methodologicalproblems with the examination of spore wall ornamentation are discussed. The data revealed confirm the high value of spore wall architecture and ornamentation in the taxonomy of this genus. The separation of B. parasiticus in a new genus Pseudoboletus Sutara is supported by its spore wall ornamentation that is unique in the Boletaceae.

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.
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.

abstract
Xerocomus truncatus Sing., Snell et Dick is recorded for the first time from Czechoslovakia in several localities in the vicinity of Prague and is transferred to the genus Boletus. The nomenclatural status of the invalid name Xerocomus porosporus Imler is also discussed. Boletus lanatus Rostk. is here considered as a variety of Boletus subtomentosus L. ex Fr. and the correct name is therefore Boletus subtomentosus var. leguei (Boud.) Bataille.
