Abstract	The fungal genus Sabuloglossum (earth tongues) was originally described as a monotypic genus based on the species Geoglossum (Microglossum) arenarium. It typically occupies sandy coastal habitats and forms mycorrhizas with Empetrum nigrum (Ericaceae). While studying material from central Europe (Czech Republic, Slovakia, Austria, and Germany), ascomata morphologically very similar to S. arenarium were observed. They were ecologically limited to mid-altitudinal mountainous habitats and associated with Calluna vulgaris or Vaccinium sp. pl. (Ericaceae). The relationship to S. arenarium and related genera was evaluated using a combination of genetic (nrITS1–5.8S–ITS2 and the 28S nrLSU regions) and comparative morphological analysis. Macro- and micromorphological investigations revealed that mountain populations differ from typical S. arenarium in longer apical cells of paraphyses, more frequently septate ascospores, and the presence of inflated cells in the stipe squamules. In phylogenetic analyses, mountain populations appeared in sister position to S. arenarium in a strongly supported clade. According to these morphological and genetic analyses, in addition to ecological and host-type specificities, the mountain populations from central Europe are proposed here as a distinct species, S. monticola sp. nov. Our study indicates that the speciation of S. monticola may have been driven predominantly by a shift in ecology and mycorrhizal association.

Abstract	In this study the environmental fate of two novel trifluoromethoxy-substituted surfactants with respectively an ether or thioether linkage were investigated, of which the design aimed for less persistency and complete mineralization. Long-term microbial transformation studies under aerobic conditions in activated sludge-wastewater medium were performed for 126 days. A semi-closed experimental system with a trapping sorbent was selected to avoid losses of possible volatile transformation products (TPs). The changes in the concentration of the surfactants and their expected TPs were monitored by target analysis using liquid chromatography-tandem mass spectrometry. Significant decrease in the concentration of the surfactants was observed over the incubation period. The main detected TPs were short-chained carboxylic acids (CAs), including a CA with two fluorinated carbon atoms representing the last product prior to mineralization. High stability of these CAs and lack in the formation of inorganic fluoride over the incubation time was however observed. Consequently, unequivocal final mineralization of the investigated surfactants could not be confirmed. Regarding the mass balance, the total amount of detected substances achieved only 30-37% of the expected concentration at the end of the incubation time. The reason of the incomplete mass balance should be further investigated.

Abstract	As a result of proposed global restrictions and regulations on current-use per-and polyfluoroalkyl substances (PFAS), research on possible alternatives is highly required. In this study, phase I in vitro metabolism of two novel prototype PFAS in human and rat was investigated. These prototype chemicals are intended to be safer-by-design and expected to mineralize completely, and thus be less persistent in the environment compared to the PFAS available on the market. Following incubation with rat liver S9 (RL-S9) fractions, two main metabolites per initial substance were produced, namely an alcohol and a short-chain carboxylic acid. While with human liver S9 (HL-S9) fractions, only the short-chain carboxylic acid was detected. Beyond these major metabolites, two and five additional metabolites were identified at very low levels by non-targeted screening for the ether- and thioether-linked prototype chemicals, respectively. Overall, complete mineralization during the in vitro hepatic metabolism of these novel PFAS by HL-S9 and RL-S9 fractions was not observed. The reaction kinetics of the surfactants was determined by using the metabolite formation, rather than the substrate depletion approach. With rat liver enzymes, the formation rates of primary metabolite alcohols were at least two orders of magnitude higher than those of secondary metabolite carboxylic acids. When incubating with human liver enzymes, the formation rates of single metabolite carboxylic acids, were similar or smaller than those experienced in rat. It also indicates that the overall metabolic rate and clearance of surfactants are significantly higher in rat liver than in human liver. The maximum formation rate of the thioether congener exceeded 10-fold that of the ether in humans but were similar in rats. Overall, the results suggest that metabolism of the prototype chemicals followed a similar trend to those reported in studies of fluorotelomer alcohols.

Abstract	Current treatment options for organic waste contaminated with per- and polyfluoroalkyl substances (PFAS) are generally limited to incineration, composting or landfilling, all resulting in emissions. Dry pyrolysis is a promising emerging alternative to these practices, but there is uncertainty related to the fate of PFAS during this process. The present work first developed a robust method for the determination of PFAS in complex matrices, such as sewage sludge and biochar. Then, a mass balance was established for 56 different PFAS during full-scale pyrolysis (2-10 kg biochar hr

Abstract	This paper studies the effect of water as an oxidation agent and also of oxygen on zinc corrosion kinetics in active state in concrete, using high-sensitivity electrical resistance sensors. It was proven that zinc corrosion in active state is strongly affected by the presence of water at its surface. Zinc corrosion in real concrete in the absence of water can be misinterpreted as salt passivity. The presence of oxygen results in an increase of zinc corrosion rate, however at pH 12.6, passivity can occur. It was verified that corrosion products consisting primarily of Ca[Zn(OH)

Abstract	Short-term mechanical alloying and compaction by spark plasma sintering was used for the production of FeAl20Si20Mo20-XNiX (X corresponds to 5-15 wt %) alloy, which showed an ultrafine-grained microstructure with dimensions of phases around 200 nm or smaller. It was found that the addition of Mo and Ni to the FeAl20Si20 alloy results in the formation of the AlMoSi phase compared to the three-phase FeAl20Si20 alloy, which initially contained FeSi, Fe

Title translation	Is lithium a teratogen?.
Abstract	Beginning with the seventies literature has brought a series of publications drawing attention to possible effects of lithium on the origin of congenital malformations. The discussion on the teratogenic effects of lithium in world literature has not come to final conclusion yet. The paper reviews some knowledge from home and foreign literature, dealing with the problems of lithium teratogenicity. A series of information has been provided on the basis of metaanalysis of data having been published until 1994 in the review systems MEDLINE, TOXLINE and Lithium Information Center database. The aim of the contribution has been to review the published data on this question. The available literature has shown that teratogenicity of lithium has not been proved univocally. Last studies rather suggest that lithium is not a strong teratogen. In view of the fact that teratogenicity of lithium cannot be safely excluded, the paper recommends that this kind of risk should be taken into account, if lithium administration is considered to be applied in pregnant women, especially during the first three months of pregnancy.

Abstract	Four new species of the Ascomycete genus Microglossum are recognized, based on morphological characters and DNA sequences of nuc rDNA (ITS region and 28S gene) and the second largest subunit of RNA polymerase II (RPB2). They differ from Microglossum nudipes by the color of the ascocarps and the sizes and shapes of ascospores, asci, and paraphyses. A lectotype is proposed, and an emended description is provided for M. nudipes. Descriptions of new species Microglossum clavatum, M. truncatum, M. pretense, and M. tenebrosum are provided. Other closely related species in the group of green earth tongues include Microglossum viride, M. rickii, and M. griseoviride. An identification key to green Microglossum species is presented.
