RAMSHAJ Q., RUSEVSKA K., TOFILOVSKA S., KARADELEV M. (2021): Checklist of macrofungi from oak forests in the Republic of Kosovo.   [fungi, taxa, Balkan Peninsula, diversity, ecology, rare species.]  Czech Mycology 73(1): 21-42   (published: 12th February, 2021)   Electronic supplement
  abstract   In the period from 2017 to 2019 a survey of the diversity of fungi in oak forests in the Republic of Kosovo was conducted. The survey included 31 localities, mainly in Quercetum frainetto-cerris and Querco-Carpinetum orientalis communities. As a result of the fieldwork performed in various seasons, a first checklist of fungi from oak forests in the country is provided. A total of 220 taxa (219 species and one forma) were identified. The majority of the identified taxa belong to Basidiomycota (206) and only 14 species to Ascomycota. The paper provides a list of all recorded species with data on locality, altitude, time of collection, forest association and type of substrate. Distribution and ecology of selected rare or threatened species are briefly discussed.

JANDA V., KŘÍŽ M., REJSEK J. (2014): Supplementary notes on Xerocomus chrysonemus (Boletaceae): bluing context and distribution in the Czech Republic.   [Xerocomus chrysonemus, Boletaceae, distribution, ecology, bluing context, Czech Republic]  Czech Mycology 66(2): 147-155   (published: 23rd December, 2014)
  abstract   The paper summarises the current state of knowledge of the distribution and ecology of Xerocomus chrysonemus in the Czech Republic. The authors present information on newly discovered localities in the Czech Republic and a yet unobserved feature of the species – bluing of the context. A distribution map based on the collections from the Czech Republic is presented and features suitable for field identification are summarised, especially with regard to X. subtomentosus, which frequently occurs together with the species in question.

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.

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   The traditional autumn mycological excursion of the Czechoslovak Mycological Society took place on October 8, 1967, in the Kersko forest, instead of the usual location of Karlštejn. About 200 species were recorded, with a notable shift from calciphilous to acidophilous fungi due to different geological conditions.
