Three new species of arbuscular mycorrhizal fungi (Glomeromycota) and revised.

Studies of the morphology and the 45S nuc rDNA phylogeny of three potentially undescribed arbuscular mycorrhizal fungi (phylum Glomeromycota) grown in cultures showed that one of these fungi is a new species of the genus in the family Diversisporaceae; the other two fungi are new species in Scutellosporaceae. sp. nov.

A new order, Entrophosporales, and three new species in Glomeromycota.

As a result of phylogenomic, phylogenetic, and morphological analyses of members of the genus , four potential new glomoid spore-producing species and , a new order, Entrophosporales, with one family, Entrophosporaceae (=Claroideoglomeraceae), was erected in the phylum Glomeromycota. The phylogenomic analyses recovered the Entrophosporales as sister to a clade formed by Diversisporales and Glomeraceae. The strongly conserved entrophosporoid morph of , provided with a newly designated epitype, was shown to represent a group of cryptic species with the potential to produce different glomoid morphs.

Three new species of arbuscular mycorrhizal fungi of the genus from maritime dunes of Poland.

Three new species of arbuscular mycorrhizal fungi of the genus (phylum Glomeromycota) were described based on their morphology and molecular phylogeny. The phylogeny was inferred from the analyses of the partial 45S rDNA sequences (18S-ITS-28S) and the largest subunit of RNA polymerase II () gene. These species were associated in the field with plants colonizing maritime sand dunes of the Baltic Sea in Poland and formed mycorrhiza in single-species cultures.

Carex pulicaris abundance is positively associated with soil acidity, rainfall and floristic diversity in the eastern distribution range.

Carex pulicaris is considered an endangered species, and further losses are forecast under the influence of even moderate climate change. Local studies indicate that temporal declines in C. pulicaris abundance are positively correlated to decreases in precipitation and increases in air temperature.

Bioaccumulation of Macronutrients in Edible Mushrooms in Various Habitat Conditions of NW Poland-Role in the Human Diet.

Recently, the interest in mushroom consumption has been growing, since their taste and low calorific value are appreciated, but also due to their nutritional value. In determining the usefulness of mushrooms in the human diet, it is important to consider the conditions of their occurrence to perform the assessment of bioaccumulation of minerals. The aim of the study was: (a) to determine the content of selected macronutrients (P, K, Ca, Mg, Na) in fruiting bodies of , , and the soils, (b) to determine their bioaccumulation potential taking into account the habitat conditions, and (c) an attempt to estimate their role in covering the requirement for macronutrients of the human organism.

New Glomeromycotan Taxa, sp. nov. and gen. nov. et sp. nov. From Brazil, and gen. nov. From New Caledonia.

Examination of fungal specimens collected in the Atlantic rain forest ecosystems of Northeast Brazil revealed many potentially new epigeous and semihypogeous glomerocarp-producing species of the phylum Glomeromycota. Among them were two fungi that formed unorganized epigeous glomerocarps with glomoid spores of almost identical morphology. The sole structure that distinguished the two fungi was the laminate layer 2 of their three-layered spore wall, which in spores of the second fungus crushed in PVLG-based mountants contracted and, consequently, transferred into a crown-like structure.
