HOLEC J., WILD J. (2011): Fungal diversity in sandstone gorges of the Bohemian Switzerland National Park (Czech Republic): impact of climatic inversion.   [macromycetes, ecology, microclimate, boreal-montane fungi]  Czech Mycology 63(2): 243-263   (published: 10th August, 2011)
  abstract   The diversity of macrofungi in 8 sandstone gorges (narrow valleys bordered by sandstone walls, mostly covered by Picea forests with admixed Fagus, alt. 170–390 m) was assessed with respect to microclimatic data from 235 stations measuring temperature and soil moisture along the elevation gradient. In total, 253 species of macrofungi were found including some boreal-montane species, species preferring moist habitats and/or species of more or less natural vegetation. Microclimatically, the bottoms of gorges are significantly colder than their slopes and slope crests during the vegetation period (climatic inversion) and show higher soil moisture throughout the year. However, they are not significantly colder during the winter period and even show a higher average minimal temperature than the rest of gorges. Generally, bottoms of sandstone gorges function as „buffers“ maintaining a stable, humid and rather cold microclimate and enabling the occurrence of some boreal-montane fungi and species requiring humid conditions. Climatic inversion is a phenomenon markedly influencing the distribution of fungi in the landscape and enabling extrazonal occurrence of some species.

ADAMČÍK S., RIPKOVÁ S., ZALIBEROVÁ M. (2006): Diversity of Russulaceae in the Vihorlatské vrchy Mts. (Slovakia).   [Russula, Lactarius, distribution, biodiversity, Slovakia, fungi]  Czech Mycology 58(1-2): 43-66   (published: 10th August, 2006)
  abstract   Russulaceae taxa were studied in selected (nine) localities in the Vihorlatské vrchy Mts. (Slovakia) in the years 2001–2003. The study was focused on their diversity, ecology and distribution. A total of 75 species were identified, from which four species, Lactarius romagnesii, Russula odorata, R. sericatula and R. zvarae, were not published from Slovakia before, and another eleven species are rare.

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.

LANDA J., FELLNER R. (1986): Some rare agarics from the Krkonoše (Giant Mountains). II. Russula salmoneolutea sp. nov.  Česká Mykologie 40(4): 234-246   (published: 7th November, 1986)
  abstract   Russula salmoneolutea sp. nov., a rare agaric from the Giant Mountains, is described. It grows in sycamore-beech forests at 800–1100 m elevation. It has a light orange to salmon-colored spore print, not fitting Romagnesi’s color scale, and distinct morphological and microscopic features that separate it from related species like R. helios or R. flavocitrina. Ecological and taxonomic data are also provided.

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.
