ŠKUBLA P. (2006): Lactarius hrdovensis, a new species of section Uvidi from Slovakia.   [fungi, Russulaceae, Lactarius, violet-coloured carpophore, papillate umbo, new species, Slovakia]  Czech Mycology 58(1-2): 67-74   (published: 10th August, 2006)
  abstract   A new species, named Lactarius hrdovensis Škubla, is described from the Západné Tatry Mts., Slovakia. The bright violet-coloured carpophores with a significant papillate umbo and yellow-whitish milk, grew among Sphagnum under Betula and Salix near a Picea forest margin. Lactarius hrdovensis belongs to section Uvidi (Konrad) Bon, subsection Uvidini Konrad. A description of macro– and microcharacters, colour photograph of fresh carpophores and line drawings of microcharacters are provided.

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.

KOCKOVÁ-KRATOCHVÍLOVÁ A., SLÁVIKOVÁ E., BREIEROVÁ E. (1984): Yeasts isolated from fruitbodies of mushrooms of the Lowland of Zahorie.  Česká Mykologie 38(4): 218-229   (published: 1984)
  abstract   Yeasts appearing on the surface of fruitbodies of mushrooms were investigated from five localities of the Lowland of Zahorie in west Slovakia in years 1981 and 1982. 224 fruitbodies were collected and 126 yeast strains isolated. 90 yeasts were identified using shortened method of identification.

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.

KUBIČKA J. (1975): Mykoflora des Naturschutzgebietes „Vyšenské kopce“ bei Český Krumlov.  Česká Mykologie 29(1): 25-34   (published: 1975)
  abstract   During 1970–1972, the occurrence of higher fungi was systematically recorded in the “Vyšenské kopce” Nature Reserve near Český Krumlov. The area lies on crystalline limestones at 500–600 m a.s.l. and is largely covered by hazel thickets. A total of 149 species were identified, with 89 species found in hazel stands. Several species are new for southern Bohemia, and for some, hazel is a new substrate in Czechoslovakia.

SCHAEFER Z. (1972): Die Gruppe Lactarius pyrogalus (Bull. ex Fr.) Fr., Stirps Pyrogalus.  Česká Mykologie 26(3): 141-148   (published: 1972)
  abstract   Species related to Lactarius pyrogalus (Bull. ex Fr.) Fr. are, in the author’s opinion, incorrectly interpreted at present. According to Fries’ original description in "Systema mycologicum," the hazel-associated species should be called Lactarius hortensis Velen., while the hornbeam or beech-associated taxon fits Lactarius pyrogalus. The author rehabilitates Lactarius adscitus Britzelm. as a species with large spores and describes new varieties of both L. hortensis and L. pyrogalus. Also, Lactarius spinosulus Quél. is included for its similar spore ornamentation and pileus characteristics.

  abstract   The 4th working conference of Czechoslovak mycologists took place in Opava, September 2–5, 1969. It focused on the geographic distribution of fungi in Czechoslovakia and mapping of selected macromycetes. The meeting included excursions and a mushroom exhibition. A detailed proceedings volume was distributed prior to the event.
