Our paper is devoted to the revision of 14 gasteromycetes taxa (13 species and 1 subspecies) which were validly published as new for science by P. E. Sosin. Type material was found for 7 species (Abstoma fibulaceum, Lycoperdon verrucosum, L. weinmannii, Nidularia heterospora, Phellorinia stepnovskii, Scleroderma poltaviense, Tulostoma chersonense); 4 specimens are deposited in KW herbarium and 3 ones- in LE herbarium. Types of the other 7 taxa (Bovistella reticulata, Calvatia fulvida, Cyathus brazlaviensis, Lycoperdon poltaviense, L. pyriforme subsp. globosum, Scleroderma sapidiforme, Tulostoma poltaviense) are probably lost. It is shown that Abstoma fibulaceum is a doubtful taxon; the other species provided with type specimens are found to be synonyms of the previously known species. To establish the correct taxonomic position of the taxa that are not supported with type specimens is impossible.

Adsorption | Year: 2011
Three sets of activated carbons (ACs) were prepared with the same precursor but activated differently (by CO2 or water vapour) with various burn-off levels. The ACs demonstrate increased deviation of the pore shape from the slitshaped model with increasing burn-off and contributions of pores of different sizes depending on the activation type. Significant re-arrangement of adsorption complexes, especially of the Van der Waals type characteristic for nonpolar or weakly polar adsorbates (H2, CH4, CH 2Cl2, CHCl3), occurs in both micropores and mesopores of ACs with decreasing temperature. The behaviour of their mixtures with water and DMSO can strongly differ from that of individual adsorbates. © 2010 Springer Science+Business Media, LLC.
