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.
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.
JANDA V., KŘÍŽ M., KOLAŘÍK M. (2019): Butyriboletus regius and Butyriboletus fechtneri: typification of two well-known species [lectotype, epitype, nomenclature, taxonomy, Czech Republic] Czech Mycology 71(1): 1-32 (published: 2nd January, 2019)
abstract
The paper deals with type material of two species of the genus Butyriboletus, which were described from the Czech Republic, originally as Boletus regius (Krombholz 1983) and Boletus fechtneri (Velenovský 1922). For both species lectotypes are designated, for B. fechtneri also an epitype. The authors present macro- and microscopic descriptions of these species based on the study of rich material including collections from the area of the type localities. Characters distinguishing both species from similar taxa are discussed.
