GABRIEL J., GRODZYNSKA G.A., NEBESNYI V.B., LANDIN V.P. (2023): Radioactive contamination of mushrooms from Polis'ke Forestry (Kyiv Region, Ukraine) long after the Chornobyl accident. [anthropogenic radionuclides, accumulation, fungi, dose, Polissya.] Czech Mycology 75(2): 117-137 (published: 12th September, 2023)
abstract
A study of the radiocaesium activity in fruitbodies of 54 mushroom species from 18 locations of Polis'ke Forestry complex was carried out with gamma spectrometry. In some mushroom samples, strontium was determined with a radiochemical method. However, the mushrooms accumulated 137Cs one to three orders of magnitude more actively than 90Sr. The highest levels of 137Cs activity, recorded in Lactarius rufus, Imleria badia, Paxillus involutus and Cortinarius praestans from the forest area at the settlement of Polis'ke in 1998 and 2000, exceeded 1 MBq/kg dry mass. By 2018, the activity of 137Cs in 60.0% and 37.84% of mushroom samples in the Zelenopolyans'ke and Steshchyns'ke Forestries, respectively, exceeded the maximum permissible level valid in Ukraine, 2,500 Bq/kg dry mass. Significant differences in the levels of contamination of the same species are noted not only at different locations, but also within the same sampling site, which is probably associated with a complex of factors which are difficult to assess, such as extremely heterogeneous nature of contamination, depth of mycelium in the soil layer, and microclimatic conditions in the place where individual fruitbodies grow. The data obtained indicate a persistent risk to the population due to internal exposure as a result of uncontrolled consumption of wild mushrooms in this region. In 2018, the potential equivalent dose per year (contribution of 137Cs only) reached maximum values of 0.239 mSv in Suillus spp. and 0.130 mSv in Imleria badia from Zelenopolyans'ke Forestry.
SALERNI E., LAGANÀ A., PERINI C., DE DOMINICIS V. (2000): Effects of various forestry operations on the fungal flora of fir woods - first results. [Species diversity, macromycetes, forestry operations, fir woods] Czech Mycology 52(3): 209-218 (published: 7th December, 2000)
abstract
The first results of the effects of some parameters on the composition of the fungal flora in Abies alba Miller woods are reported. Medium thinning and removal litter seems to have contributed to a slight increase in species diversity. Moreover, the results suggest that this type of study should be continued and extended to other areas, to obtain a large amount of data.

KUTHAN J. (1982): A new species of the genus Tricholoma: Tricholoma singeri spec. nova. Česká Mykologie 36(1): 7-10 (published: 1982)
abstract
Based on detailed study and own collections, the author concludes that Tricholoma maluvium in the sense of Bresadola is a separate species. It is described as Tricholoma singeri spec. nova, in honour of Prof. Dr. Rolf Singer. The name “Tricholoma maluvium (Fr.) Bres.” in the sense of Fries is shown to be dubious.
MICKA K., KLÁN J. (1980): Chemical spot tests of macromycetes with benzidine. Česká Mykologie 34(2): 74-81 (published: 1980)
abstract
Macrochemical colour reactions of benzidine were studied mainly with the species of genera Agaricus, Amanita, Lactarius, Russula, and Tricholoma. With the genus Lactarius, differences were found between the reactions of the milk and the context. Oxidation enzymes, which give a blue-green, blue, or black reaction, were detected in many species of the genera Agaricus, Lactarius, and Russula, whereas with Amanita and most species of Tricholoma they were absent. In the case of the genus Russula, only species with a burning taste give a yellow or ochre reaction. The reactions of benzidine are suitable as complementary characteristics for the determination of some mutually similar species.
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.
DERMEK A. (1978): A contribution to the mycoflora of the forests on environs of the villages Brodské, Čáry, Gbely, Kopčany, Kúty and Smolinské (Western Slovakia). (with coloured plates No.93 and 94). Česká Mykologie 32(4): 215-225 (published: 1978)
abstract
The author gives a brief characterization of the territory in Western Slovakia around Brodské, Čáry, Gbely, Kopčany, Kúty, and Smolinské, and enumerates the fungi species found there between 1963 and 1977. Some rare species are highlighted: Hydnellum spongiosipes, Lepista graveolens, Leucopaxillus tricolor, Amanita rubescens f. annulo-sulfurea, and Leccinum thalassinum. A new combination Lepista graveolens (Peck) Dermek is proposed.
DRBAL K., KALAČ P. (1976): Content of cobalt in some edible mushrooms. Česká Mykologie 30(1): 24-26 (published: 1976)
abstract
In this paper the content of the trace element cobalt was determined in 15 species of common edible mushrooms from three localities of the South Bohemia region. The content varied in the range from 0.3 to 4 mg Co/kg of dry matter. The highest content of cobalt was found in Xerocomus subtomentosus (L. ex Fr.) Quél., Agaricus campestris L. ex Fr. and Ixocomus variegatus (Sow. ex Fr.) Quél., the lowest one in Xerocomus badius (Fr.) Kühn. ex Gilb. The determined content in the same species of mushroom found on different localities differed, what proved the influence of every particular place where a mushroom was found. The possible factors are discussed.
DRBAL K., KALAČ P., ŠEFLOVÁ A., ŠEFL J. (1975): Content of copper in some edible mushrooms. Česká Mykologie 29(3): 184-186 (published: 1975)
abstract
Copper content was measured in 15 edible mushroom species from South Bohemia. Concentrations ranged from 8 to 179 mg/kg dry weight, with Lepiota procera showing the highest levels. Results varied by location, with implications for human dietary intake of copper.
DRBAL K., KALAČ P., ŠEFLOVÁ A., ŠEFL J. (1975): Content of the trace elements iron and manganese in some edible mushrooms. Česká Mykologie 29(2): 110-114 (published: 1975)
abstract
Ash, iron and manganese contents were determined in 15 edible mushroom species from three localities in South Bohemia. Ash content ranged from 5–15% of dry matter, iron 70–1530 mg/kg, and manganese 9–100 mg/kg. The highest concentrations were found in Ixocomus variegatus, the lowest in Xerocomus badius. Results varied by site, showing habitat influence.
PŘÍHODA A. (1971): Suillus sibiricus (Sing.) Sing. et les associations mycorrhiziques de l’arole (Pinus cembra) en Tchécoslovaquie. Česká Mykologie 25(3): 140-146 (published: 1971)
abstract
Suillus sibiricus (Sing.) Sing., described from the Altai region in 1938, was later recorded in the Alps and the Pacific Northwest of North America. In Czechoslovakia, it was found in the Belanské Tatry mountains in 1970. This boletus forms mycorrhizal associations with Pinus cembra in Europe and Pinus sibirica in Asia. The occurrence of Tricholoma terreum as a second symbiont of Pinus cembra was also noted. The paper details ecological and distributional observations.
HERINK J., KOTLABA F. (1967): Distributio Tricholomatis pardini in Čechoslovakia et notula de eius nomone correcto. Česká Mykologie 21(1): 1-11 (published: 20th January, 1967)
abstract
The authors deal with a species of Tricholoma previously referred to in mycological literature as Tricholoma pardinum or Tricholoma tigrinum. They determined that these names are invalid under the international rules of botanical nomenclature, and therefore describe this mushroom as a new species, Tricholoma pardalolum sp. nov. They also discuss the ecology of this thermophilic and calciphilous species and its distribution in Czechoslovakia, listing all known localities due to its toxic nature.
SEMERDŽIEVA M. (1965): Kultivierungen und morphologische Untersuchungen einiger Pilze der Familie Agaricaceae in vitro. Česká Mykologie 19(4): 230-239 (published: 1965)
abstract
The study reports on the cultivation and morphological study of 57 species of Agaricaceae under in vitro conditions using explant methods. It includes descriptions of colony growth, mycelial structure, and microscopic features such as hyphae and spores. The work aims to develop identification techniques for laboratory cultures and to support physiological and biochemical studies of these fungi.

abstract
The article compares pine forests on aeolian sands in Rohatec (South Moravia) and Šajdíkové Humence (West Slovakia), focusing on soil properties, vegetation, and macrofungi. Forests in Doubrava near Hodonín were once dominated by oak, later replaced by Scots pine. In contrast, pine is native to the Záhorská nížina region. Historical vegetation development and ecological characteristics are discussed.
