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.

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.
ZELENÝ L. (2006): Taxonomic literature on the genus Lepiota s. l. in the Czech Republic. [Lepiotaceae, Lepiota s. l., taxonomic literature, Czech Republic] Czech Mycology 58(3-4): 225-265 (published: 29th December, 2006)
abstract
A literary checklist of the genus Lepiota s. l. was compiled by excerpting Czech taxonomic literature. The list is based on taxonomic papers in which the genus Lepiota is discussed and includes 165 names. It contains also species mentioned in some mycofloristic papers. A separate chapter deals with species described by J. Velenovský.
SEEGER R. (1995): Vergiftungen durch höhere Pilze (Intoxications by higher fungi.) [Fungal intoxications, muscarine, amatoxins, hallucinogenic fungi, Cortinarius toxins] Czech Mycology 48(2): 97-138 (published: 25th September, 1995)
abstract
Article presents a review of poisonous macrofungi and their toxic constituents concerning chemistry, site and mechanism of action, absorption, fate and excretion of the main toxins and signs, diagnosis, treatment and course of human poisoning. Considered are macrofungi containing 1. Irritants of the gastrointestinal tract with rapid onset of action. 2. Muscarine in Inocybe and Clitocybe species. 3. Toxins affecting the central nervous system, i.e. ibotenic acid resp. muscimol in Amanita muscaria and A. pantherina and hallucinogenic indoles in Psilocybe, Panaeolus und related species. 4. Toxins affecting parenchymatous organs with delayed onset of symptoms, causing mainly liver and/or kidney injury: The cyclopeptides in Amanita phalloides, A. virosa and A. verna and in Galerina and Lepiota species. Gyromitrine resp. methylhydrazine in Gyromitra esculenta. Cortinarius toxins in C. orellanus, C. speciosissimus and related species. 5. Miscellaneous substances, not necessarily toxic per se, e.g. coprin in Coprinus atramentarius which produces disulfiram-like effects when consumed with alcohol. - Intolerance to trehalose in persons with a genetic deficiency of the intestinal enzyme trehalase. - Hypersensitivity reactions to ingested or inhaled antigens of edible mushrooms, e.g. skin and respiratory reactions or even immunohaemolytic reactions complicated by secondary renal failure.
