VAŠUTOVÁ M. (2008): Taxonomic studies on Psathyrella sect. Spadiceae. [Psathyrella, Czech Republic, Slovakia, sect. Spadiceae, distribution, ecology] Czech Mycology 60(2): 137-171 (published: 27th February, 2009)
abstract
Descriptions, figures of microscopic characters, data on ecology and distribution of four species of Psathyrella section Spadiceae known from the Czech Republic and Slovakia are given. These species are P. spadicea, P. papyracea, P. pygmaea and P. spintrigeroides. Type material of P. variata, P. imleriana, P. olympiana and P. spintrigeroides has been examined and the insufficiently known taxa P. variata, P. imleriana, P. subcernua and P. sarcocephala are discussed. The newly published combination Psathyrella papyracea (Pers.: Fr.) Vašutová is shown to be the correct name for a fungus currently named P. cernua (Vahl: Fr.) Hirsch. An identification key for Psathyrella species with thickwalled cystidia occurring in Central Europe is presented.
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.
ŠUTARA J. (2014): Anatomical structure of pores in European species of genera Boletus s.str. and Butyriboletus (Boletaceae). [Boletaceae, anatomy, pores, cheilocystidia] Czech Mycology 66(2): 157-170 (published: 23rd December, 2014)
abstract
One of the characteristic features of European species of genera Boletus s.str. and Butyriboletus is a conspicuous development of their cheilocystidia covering their pores in youth. The development of this type of cheilocystidia is partly supported by the growth of hyphae of the hymenophoral trama under the cheilocystidia. This special arrangement of cheilocystidia is an important diagnostic character distinguishing European species of the above-mentioned genera from other groups of boletes in Boletaceae. The microscopical structure of this type of pores is described in detail.
