BOUŠKA I., ŘEHÁNEK L., MOTYČKA K., VESELSKÝ J. (1980): Detection of UV-fluorescence in renal tissues in Cortinarius orellanus Fr. poisoning.  Česká Mykologie 34(4): 188-190   (published: 1980)
  abstract   Blue UV-fluorescence was observed in renal tubuli of the kidney of the child, who died following the Cortinarius orellanus poisoning. Analogous changes were noted in the kidneys of experimentally intoxicated guinea pigs. The detection of the UV-fluorescence in renal tissues could be the key procedure besides the clinical, morphological and mycological findings helpful in the diagnosis of the intoxication with Cortinarius subg. Leprocybe Moser, section Orellani Moser 1969.

PILÁT A. (1970): Cortinarius orellanus Fr. et species affines (Explicatio ad tabulam coloribus impressam).  Česká Mykologie 24(3): 121-124   (published: 20th July, 1970)
  abstract   In the explanation of the colored plate accompanying this issue, the author discusses the distribution of Cortinarius orellanus Fr. in Czechoslovakia. A specimen from North America, reported under the same name, is probably not identical with the European species. Even within Europe, taxa labeled as C. orellanus vary significantly, particularly in pigmentation. The systematic value of many segregates is thus unclear, and even the toxicology of C. orellanus remains unresolved. The second species illustrated, C. speciosissimus Kühner & Romagn., has not yet been found in Czechoslovakia.

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.

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.

KLÁN J., BAUDIŠOVÁ D. (1994): Enzyme N-acetyl-β-D-glucosaminidase (NAG) as an early marker of intoxications by the Cortinarius species (nephrotoxic syndrom).   [Cortinarius species, nephrotoxic syndrom, enzyme N-acetyl-β-glucosaminidase]  Czech Mycology 47(1): 65-72   (published: 6th January, 1994)
  abstract   The enzyme N-acetyl-β-D-glucosaminidase (EC 3.2.1.30; NAG) was evaluated as a marker of intoxications by the Cortinarius mushroom (nephrotoxic syndrom).Enzyme activity wasmeasured in the urine after i.p. applications of Cortinarius orellanus (Fr.) Fr. and C. rubellus Cooke species, respectively, by fluorimetric and/or colorimetric methods. Considerably higher level of the enzyme (up to 50 times) was observed already on the first day after intoxication, when other s markers of renal damage (e.g. hematuria) were without changes. The high level of enzyme activity was detected up to 4th day after intoxication. The picture of intoxication was completed by determination of the urea level in serum and by histological examinations.

KUBIČKA J. (1980): Giftige Schleierlinge (Gattung Cortinarius).  Česká Mykologie 34(1): 3-8   (published: 1980)
  abstract   The present paper deals with poisonous species of the genus Cortinarius. According to the toxicity, the species were classified into five groups: (1) species containing orellanine confirmed as deadly poisonous; (2) species with orellanine toxic only to animals; (3) suspected species with fluorescent orellanine-like substances; (4) species with emodin; (5) species with other toxic substances. Since 1957, when poisonings caused by Cortinarius orellanus were discovered in Poland, similar cases have been reported from Switzerland, Germany, France, and Czechoslovakia. Poisonings by Cortinarius speciosissimus have also been described. Toxicity was confirmed by animal experiments. Section Orellani is characterized by blue fluorescence and specific chromatographic patterns. Recently, Cortinarius gentilis (section Limonei) has also been confirmed as toxic. Other species in section Limonei, such as Cortinarius saniosus, are suspected but untested. So far, only a few species of Cortinarius have been tested experimentally, and only a few, mainly from subgenus Phlegmacium, are considered edible.
