LIZOŇ P. (1982): Mushroom poisoning by Omphalotus olearius (DC. ex Fr.) Sing. and distribution of the fungus in Slovakia.  Česká Mykologie 36(3): 154-159   (published: 1982)
  abstract   Nuclear relationships in hyphae of the basidiomycete Agrocybe aegerita were studied using phase contrast microscopy and in vivo observation of terminal and subterminal cells from microcultures. While dikaryotic cultures showed the expected 2 nuclei per cell, monokaryotic cultures displayed multinucleate terminal cells with 2–8 nuclei, and 2 nuclei in subterminal cells. This phenomenon was observed under various media, cultivation temperatures, and incompatibility factor combinations. It indicates that several mitotic divisions precede septum formation in monokaryotic hyphae. Monokaryotic fructification is also known in Agrocybe aegerita.

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.

(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.

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.

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.

  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.

  abstract   The Laboratory of Experimental Mycology, Institute of Microbiology, Czechoslovak Academy of Sciences, Prague, takes care for a culture collection of Basidiomycetes, which now includes 130 species (280 strains). The cultures were mainly obtained by the explant method from fresh fruit-bodies collected in their natural localities in Czechoslovakia, some of them were isolated from basidiospores or from substrate mycelium. A small part of mycelial cultures was obtained on an exchange basis from various international institutions. The mycelial cultures are used for purposes of investigating their physiology of growth and biochemical activities.

  abstract   An attempt was made to record mushroom poisonings in Czechoslovakia within one district (South Bohemian region with 1.5 million inhabitants). In 1965, there were 28 poisonings involving 48 people and 1 death. 42 people were hospitalized for a total of 239 days. The most serious poisonings were caused by Gyromitra esculenta, while the most frequent poisonings were due to Amanita pantherina.
