Opis:
The paper concerns a very rare and poorly known species of green alga Chlorodiscus natans Petersen & Hansen, discovered in the peat bog "Brzeźnik" near Bolesławiec (Poland). This is the second stand so far discovered in the world. The collected material allowed complementing the knowledge on organization of colonies, morphology and way of hair development. The remaining features, particularly the structure of the cell, are in concordance with the hitherto diagnosis of that species. The paper presents problems connected with the taxonomic affiliation of the species and describes the ecological conditions of habitats occupied by this alga.

Opis:
Dicranochaete quadriseta (Korš.) Nov. and Pop. was collected during investigations of algae from mountain peat bogs of the Sudeten Mts (Poland). The paper describes the morphology, taxanomy, geographical distribution and ecological conditions of this species. This very rare species was found in an oligominerotrophic peat bog called "Topieliska-Zieleniec" near Duszniki (Orlickie Mts).

Opis:
Hormotila ramosissima Korš., a very rare in the world and poorly known species, have been found in peat bogs of Lower Silesia. The growth stages typical of this species but unknown so far, have been described and illustrated. It was found that this species has many features in common with the representatives of Volvocales, Tetrasporales, and chlorococcales. The regularly observed zoospores and hemizoospores, which accompanied the various developmental stages of that species, showed an internal structure of Chlamydomonas-type. Studies on Hormotila ramosissima were based on live material collected in ample quantities from peat bogs. The collected in this way repeatable and abundant data allowed to discuss problems concerning morphology, reproduction and development, as well as consider the taxonomic position this species.

Opis:
The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors and the structure of microflora communities remain largely unclear. This study was conducted in Hornsund Bay, which exhibits large variability in the physicochemical characteristics of habitats, particularly with regard to the availability of nitrogen and phosphorus. This variability, to a large degree, is caused by seabird colonies, which fertilize nutrient-poor terrestrial ecosystems near their nesting areas. The large variations in ecological conditions and vegetation types in the study area aid assessment of habitats representing different combinations of factors potentially influencing the formation of cyanobacterial and algal assemblages. The aim of this study was to examine the influence of physicochemical parameters on the taxonomic composition and diversity of green algae and cyanobacteria (particularly the coccoid, oscillatorialean, and heterocystous taxa). The study encompassed two groups of habitats – soil surface habitats and water-saturated habitats, both characterized by diverse influences of seabird colonies, vegetation cover, and moisture. Our results showed that taxonomic diversity and composition of cyanobacteria and algae were mainly influenced by P–PO₄³⁻, N–NH₄⁺ and Ca²⁺ (soil surface habitats), and NO₃⁻, as well as moisture (index of wetness) and pH (water-saturated habitats). The variability of these physicochemical properties was largely due to the variability of the seabird colony influence. Taken together, our findings aid in understanding the processes of formation of phycoflora assemblages in Arctic tundra.
