abstract
Several rare fungi, including Lepiota fuscovinacea, Cortinarius percomis, and Hygrophorus pudorinus, were recorded on limestone-rich hill Ostrý near Domanice in South Bohemia. The study emphasizes the area's diverse and calciphilous mycoflora.

abstract
The species diversity of the family Russulaceae was studied at four representative sites located in forests dominated by Pinus sylvestris on sandy soils in the Záhorská nížina lowland in the years 2010–2012. The diversity varies from 7 to 10 species per site. There is a high variation in species composition and frequency rates between the studied sites. At all four sites, members of two Russulaceae genera were represented: Lactarius with two recorded species in total, while Russula with 19 species.The species diversity of Russulaceae in the area of Záhorská nížina is estimated based on data from the representative sites, revision of herbarium material, and published data. Nineteen species were identified in the studied herbarium material, and together with the data from the representative sites this amounts to a total of 27 Lactarius and Russula species associated with Pinus and reported from the area. Published reports on the occurrence of three more species of these two genera, reported to be associated with pine trees in the area, have not been confirmed.

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.
