    Abstract This article presents the ecological distribution of the edible and medicinal mushroom Polyporus umbellatus in Central Europe. Our main motivation is to describe the potential for commercial cultivation of this species. All data considered in this study are based on records from 70 localities in Slovakia. Fruiting bodies and sclerotia have been recorded in forests in which beech, hornbeam, and oak dominate, at altitudes ranging from 150 to 935 m (mean altitude, 403 m). In Slovakia, these areas correspond to warm, hilly, and upland beech-oak and oak-beech forests. Mean annual air temperature between 6°C and 9°C characterizes about 94% of the areas. Continuous monitoring of fruiting body production at 13 plots showed peak growth in August. In total, 192 fruiting bodies were recorded over a 5-year period. P. umbellatus predominantly grows in acidic soils (pH 4.5-4.99), with no individuals found in soils with pH above 7.0. Our findings can be used for growing the fungus and expanding its growth to new regions, not only in Central Europe.

    Abstract Rhizopogon salebrosus, a common species found in western North America, has been recently considered an invasive species in Europe, based on ITS rDNA sequence records from ectomycorrhizal root tips. We collected in montane and submontane coniferous forests (both plantations and unmanaged forests) in the Czech Republic and Slovakia basidiocarps of a species with morphology similar to R. salebrosus. Analysis of sequences of ITS rDNA showed that our collections together with further records from Europe belonged into the R. salebrosus species group. In contrary, they formed a well-supported clade based on analysis of a gene for RNA polymerase II second largest subunit and one anonymous nuclear locus developed for better resolution in the R. salebrosus species group. Evidence from the three genes and distinct phenotypic characteristics show that the European collections represent a novel species within R. salebrosus species group that is described herein as R. confusus. Host affinity of R. confusus, its native presence in Europe and implications for the presumed invasion of R. salebrosus in Europe are discussed.

    Abstract The data presented in this article are related to the research article entitled “Habitat preferences of Hericium erinaceus in Slovakia” (Kunca and Čiliak, 2016) [FUNECO607] [2]. The dataset include all available and unpublished data from Slovakia, besides the records from the same tree or stem. We compiled a database of records of collections by processing data from herbaria, personal records and communication with mycological activists. Data on altitude, tree species, host tree vital status, host tree position and intensity of management of forest stands were evaluated in this study. All surveys were based on basidioma occurrence and some result from targeted searches.

    Abstract Distribution patterns, ecology and habitats of Hericium erinaceus in Slovakia are presented, together with an indication of its population size and dynamics as driven by the type of substratum the fungus feeds on. Basidiomata have been recorded both on living and dead trees, predominantly on oaks (Quercus spp.) but also on European beech (Fagus sylvatica), and at altitudes ranging from 103 to 753 m, which in Slovakia corresponds to warm hilly and upland beech-oak forests. Standing trunks were a more common substratum than fallen trunks. Although the fungus tends to occur in old-growth forests, nearly half of the observations were from managed forests. Given the observed distribution, we conclude that H. erinaceus is not a strict indicator of intact old-growth forests in Slovakia.

    Abstract In the present work, we focused on two aspects of mercury (Hg) bioconcentration in the above-ground parts of Neoboletus luridiformis. In the first part, we monitored the bioconcentration potential of individual anatomical parts of a particular fruiting body and evaluated the obtained data by the spline interpolation method. In the second part, we focused on assessing the mercury content in 378 samples of N. luridiformis and associated samples of substrates from 38 localities with different levels of Hg content in Slovakia. From the obtained data of Hg content in samples of substrate and fungi, we evaluated ecological indicators (geoaccumulation index – Igeo, contamination factor – Cf a potential ecological risk – PER), bioconcentration indicators (bioconcentration factor – BCF; cap/stipe quotient – Qc/s) and health indicators (percentage of provisional tolerable weekly intake – %PTWI a target hazard quotient – THQ). Based on the Hg distribution results, the highest Hg content was found in the tubes & pores (3.86 mg/kg DW), followed by the flesh of cap (1.82 mg/kg DW). The lowest Hg content was in the stipe (1.23 mg/kg DW). The results of the BCF values indicate that the studied species can be included in the category of mercury accumulators. The results of the ecological indices representing the state of soil pollution pointed out that two localities (Malachov and Nižná Slaná) stood apart from all monitored localities and showed a state of an extremely disturbed environment. This fact was also reflected in the values of Hg content in the fruiting bodies of the studied mushroom species. In the case of the consumption of mushrooms from these localities, it can be stated that long-term and regular consumption could have a negative non-carcinogenic effect on the health of consumers. It was confirmed by the %PTWI (Malachov: 57.8%; Nižná Slaná: 53.2%) and THQ (Malachov: 1.11 Nižná Slaná: 1.02). The locality Čačín-Jelšovec is interesting from the bioconcentration characteristics point of view, where the level of environmental pollution was the lowest (Hg content in the soil was below the background value) compared to other localities, however, the THQ value was the highest (1.29).

    Abstract Wild-growing edible mushrooms are valuable food with a high content of proteins, fibers, antioxidants, and they are characterized by their specific taste and flavor. However, from an ecotoxicological point of view, they are a risk commodity because of their extremely high bioaccumulative capacity to accumulate the risk elements and contaminants from the environment.
