TORTIĆ M. (1968): Fungus collections in the Pinus peuce forests in the Pelister National Park (Macedonia, Jugoslavia).  Česká Mykologie 22(3): 189-201   (published: 1968)
  abstract   85 species of higher fungi were found in Pinus peuce forests on Pelister Mountain during two excursions in October 1966 and 1967. Several species are new to Yugoslavia or considered rare. Suillus sibiricus and Gomphidius helveticus were observed forming mycorrhiza with P. peuce. Some lignicolous fungi were reported on this pine for the first time.

TUDU D., CHAKRABORTY D., GHOSH A. (2024): Morphology and molecular phylogeny of Scleroderma yunnanense and Tricholoma olivaceum, two edible mushrooms new to India.   [Basidiomycota, Meghalaya, nrITS, taxonomy, edibility, ethnomycology.]  Czech Mycology 76(2): 111-124   (published: 22nd August, 2024)
  abstract   Macrofungal explorations conducted in several forested areas of the East Khasi Hills and Ri Bhoi Districts of Meghalaya, India, unveiled two noteworthy members of Scleroderma and Tricholoma. After careful morphological characterisation, literature consultation, and molecular phylogenetic analysis, the species were identified as Scleroderma yunnanense and Tricholoma olivaceum, taxa recently described from China. The local tribal communities highly value these species as food. Here, we provide comprehensive morphological descriptions complemented with illustrations, comparisons with similar species, and nrITS-based phylogenetic analyses. Scleroderma yunnanense and Tricholoma olivaceum are reported for the first time from India.

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.

KŘÍŽ M., JANDA V. (2016): First records of Tricholoma bresadolanum (Agaricales) in the Czech Republic.   [Tricholomataceae, description, ecology, Bohemia, Moravia]  Czech Mycology 68(1): 97-108   (published: 31st May, 2016)
  abstract   The paper reports on the first collections of Tricholoma bresadolanum in the Czech Republic. The authors present a macro- and microscopic description based on a study of material collected at two localities in the Bohemian Karst Protected Landscape Area in Central Bohemia. The species was also documented from another two sites in Moravia. The characters distinguishing T. bresadolanum from similar species of the genus Tricholoma are discussed.

HOLEC J., KŘÍŽ M., POUZAR Z., ŠANDOVÁ M. (2015): Boubínský prales virgin forest, a Central European refugium of boreal-montane and old-growth forest fungi.   [Mt. Boubín, Bohemian Forest, Czech Republic, Basidiomycota, Ascomycota, diversity, ecology, distribution]  Czech Mycology 67(2): 157-226   (published: 10th September, 2015)
  abstract   Boubínský prales virgin forest is the best-preserved montane Picea-Fagus-Abies forest in the Czech Republic. Its core area (46.67 ha), grown with original montane forest never cut nor managed by foresters, has been protected since 1858. It represents the centre of the present-day nature reserve (685.87 ha). A detailed inventory of its fungal diversity was carried out in 2013–2014. Ten segments differing in habitat and naturalness were studied (235 ha). The total number of species was 659, with the centre of diversity in the core area (503 species) followed by the neighbouring segments grown by natural forests minimally influenced by man. When literature and herbarium data are added, the total diversity reaches a total of 792 taxa. The locality represents a unique refugium for some borealmontane fungi (e.g. Amylocystis lapponica, Laurilia sulcata, Pholiota subochracea), a high number of rare species preferring old-growth forests (Antrodia crassa, A. sitchensis, Baeospora myriadophylla, Chrysomphalina chrysophylla, Fomitopsis rosea, Ionomidotis irregularis, Junghuhnia collabens, Skeletocutis odora, S. stellae, Tatraea dumbirensis), wood-inhabiting and mycorrhizal fungi confined to Abies (Panellus violaceofulvus, Phellinus pouzarii, Pseudoplectania melaena, Lactarius albocarneus), and a high number of indicators of well-preserved Fagus forests (e.g.Climacodon septentrionalis, Flammulaster limulatus, Pholiota squarrosoides). Several very rare fungi are present, e.g. Chromosera cyanophylla, Cystoderma subvinaceum and Pseudorhizina sphaerospora. The value of the local mycobiota is further emphasised by the high number of protected and Red List species. Comparison with other Central European old-growth forests has confirmed that Boubínský prales is a mycological hotspot of European importance.

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.

LAGANÀ A., SALERNI E., BARLUZZI C., PERINI C., DE DOMINICIS V. (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.

STERNER O., ANKE H. (1995): Toxic terpenoids isolated from higher fungi.   [Terpenoids, toxicity, biological activity, higher fungi, Basidiomycotina]  Czech Mycology 48(1): 39-52   (published: 16th May, 1995)
  abstract   A large number of toxic terpenoids have been isolated from cultures and fruit bodies of higher fungi. The chemistry, biological activity and possible natural functions of some of them are discussed in this paper. Especially interesting in this respect are natural defensive compounds that possess for example antibiotic and antifeedant activities and are likely to be toxic. The sesquiterpenoids of the pungent Lactarius species (e.g. L. necator, L. piperatus, L. rufus and L. vellereus) constitute an interesting example of this. In the fruit bodies of these species within seconds after a physical injury, an apparently inactive precursor is converted enzymatically into a range of pungent sesquiterpenes with an unsaturated dialdehyde functionality possessing potent antimicrobial and cytotoxic activities. The injury brings the precursor, which is present as an emulsion in the latex of specialised hyphae of the fruit bodies, in contact with the enzyme systems that are kept apart in the intact fruit body. Fruit bodies of non-pungent and edible Lactarius species (e.g. L. deliciosus and L. flavidulus) contain precursors with completely different chemical structures that also are converted as a response to injury, although to products with less striking biological activities and with uncertain function.

HOLEC J. (1993): Ecology of macrofungi in the beech woods of the Šumava mountains and Šumava foothills.  Česká Mykologie 46(3-4): 163-202   (published: 25th August, 1993)
  abstract   The fungi of the order Agaricales s. l. and several families of ungilled fungi and gasteromycetes were studied in the beech woods of the southeastern part of the Sumava mountains and Sumava foothills (Czechoslovakia). Altogether, 230 species were recorded on 8 permanent plots (50 x 50 m) during the years 1988 - 1990. The terrestrial fungi were closely associated with a particular layer of the surface humus and substrate, and the lignicolous fungi were associated with wood in various stages of decay. The occurrence of mycorrhizal fungi was influenced above all by the mycorrhizal partner, altitude, and climate. The species composition, number of mycorrhizal and terrestrial species on the individual plots, and their share were determined by the humus type, microrelief, and the thickness of the detritus layer. The occurrence of lignicolous fungi was in close relation to the degree of naturalness of the wood, substrate diversity of the plot and the mesoclimate. The results are summarized in the mycosociological tables and compared by the use of cluster analysis and diagrams.

KLÁN J. (1990): Lignin test - its mycotoxicological and chemotaxonomical significance.  Česká Mykologie 44(4): 220-224   (published: 26th November, 1990)
  abstract   A total of 135 species of Basidiomycetes were analyzed using the lignin test. Though not specific for amanitins or tryptamine derivatives, the test is useful in chemotaxonomic studies of genera Russula, Lyophyllum, Amanita, and Psilocybe.

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.

CUDLÍN P., MEJSTŘÍK V., ŠAŠEK V. (1980): The effect of the fungicide Dithane M-45 and the herbicide Gramoxone on the growth of mycorrhizal fungi in vitro.  Česká Mykologie 34(4): 191-198   (published: 1980)
  abstract   The minimum inhibiting concentration of the fungicide Dithane M-45 and the herbicide Gramoxone was determined in pure cultures of 13 species of fungi forming mycorrhizae with Pinus sylvestris L., grown under submerged conditions (reciprocal shaker). According to their pesticide sensibility the fungal species were divided into five groups. Gramoxone showed a less intensive inhibition than Dithane M-45.

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.

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.

  abstract   An attempt was made to record mushroom poisonings in Czechoslovakia within one district (South Bohemian region with 1.5 million inhabitants). In 1965, there were 28 poisonings involving 48 people and 1 death. 42 people were hospitalized for a total of 239 days. The most serious poisonings were caused by Gyromitra esculenta, while the most frequent poisonings were due to Amanita pantherina.

ŠAŠEK V., MUSÍLEK V. (1968): Antibiotic activity of mycorrhizal Basidiomycetes and their relation to thehost-plant parasites.  Česká Mykologie 22(1): 50-55   (published: 1968)
  abstract   35 strains (17 species) of mycorrhizal Basidiomycetes were cultured with Pinus silvestris seedlings. The fungi showed only slight antibiotic activity, which did not increase with seedling presence. In 12% of tests, growth of parasitic fungi was inhibited. Rhizoctonia solani was the most inhibited species.

  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.
