As a result of the research carried out in Lakes Duszatyńskie and the Olchowaty stream, a new European site with Geissleria declivis (Hust.) Lange-Bert. was found — a new species for Poland. The highest abundance of G. declivis has been observed on sandy substrate and small stones in the littoral zone of the Upper Lake during the spring season. The species occurred together with Achnanthidium minutissimum (Kütz.) Czarn. var. minutissimum, A. catenatum (Bily & Marvan), Fragilaria leptostauron (Ehrenb.) Hust. var. leptostauron and F. pinnata Ehrenb. var. pinnata. Our observations revealed that G. declivis develops in lentic water bodies with medium organic matter content and neutral pH. The species seems to prefer mesotrophic waters with low to medium electrolyte content and oligosaprobous. The species morphology and identity is documented in a series of light microscopic (LM) images and for the first time under a scanning electron microscope (SEM).

W latach 2010-2011 badano zbiorowiska okrzemek w wodach Białej Tarnowskiej i Ropy. Stwierdzono obecność Didymosphenia geminata (Lyngbe) M. Schmidt na nowych stanowiskach na terenie Polski południowej. Na terenie Europy do niedawna występowała bardzo rzadko, zwłaszcza w zimnych, oligotroficznych wodach w górnych biegach potoków. Pojedyncze okazy tego gatunku występują w rzekach - Ropie i Białej. W sezonie wiosennym obserwowano go licznie w rzece Ropie poniżej zbiornika zaporowego "Klimkówka", gdzie tworzył maty i galaretowate styliki.

Studied territory involved two rivers: the Ropa River and the Biała River, both having its sources in the Low Beskid. The Ropa River is the biggest left-bank inflow of the Wisłoka River, running on its all length through two mesoregions (the Low Beskid and the Gorlickie Depression, few geographical regions and two Provinces (the Małopolska Province and the Podkarpacie Province). The valley of the Biała Tarnowska River is the right-bank inflow of the Dunajec River, which spreads through the Central Beskidian Piedmont. Materials to researches were taken in 2010-2011, from waters of the Biała Tarnowska River and the Ropa River. The aim of the work was to indicate new studying posts on both rivers, on which the existence of D. geminata was stated and to carry out a taxonomic analysis of populations with a determination of environmental conditions in studied liquids. Didymosphenia geminata was stated in all studying post with an exception of the last one located on the Biała River. It existed in forms of individual specimen, mainly on rocks. It formed bigger populations only on the Ropa River below the dammed reservoir "Klimkówka" - was observed on stalks in the Spring and Autumn seasons, it also formed mats in the Spring season.

Water of the San River was characterized by good and high ecological status and high diatom richness. During four studied seasons at two sites 353 diatom taxa were identified in total, from which the most numerous were Achnathidium pyrenaicum (Hust.) Kobayasi and Achnanthidium minutissimum (Kütz.) Czarnecki var. minutis-simum. Water of the San River, was characterized by high and good water quality (II and I class) in all seasons and at both studied sites.

The studies were conducted on watercourses flowing out of raised peat bog areas in Orawsko-Nowotarska Basin and raised peat bogs and transitional moor in „Międzyrzeki” Reserve on the territory of the Roztocze National Park. New localities where Neidium hercynicum occurred were found on the peatland areas of Southern Poland (Orawsko-Nowotarska Basin) and South-eastern (the Roztocze National Park) during the studies conducted on Jamów, Tokarka and Chyżny streams and on the territory of “Międzyrzeki” Reserve between 2007–2013. Longer and wider specimens were found on both investigated sites in comparison to the dimensions listed in the Krammer and Lange-Bertalot key. N. hercynicum were always found as individual specimens.

Matysówka stream is small, under 6 km long watercourse, which is a right-bank tributary of Strug River. In 2009–2011studies on the subject of diversity of diatom communities using diatom indices IPS, GDI and TDI for water quality assessment were conducted. On the stream 271 diatom taxa were identified, among which: Achnanthidium minutissimum var. minutissimum, Navicula cryptotenella, N. gregaria, N. lanceolata, N. tripunctata, Nitzschia linearis, N. pusilla, N. recta, Planothidium frequentissimum, Rhoicosphenia abbreviata were the most frequent. Middle and lower section of Matysówka stream was characterized by increased concentrations of phosphates, nitrites, ammonium, total phosphorus and nitrogen, BOD5. On the basis of diatom indices IPS and GDI waters were characterized as III–IV quality classes, while the TDI index revealed the worst water quality classes (IV–V).

The aim of the present work conducted in the area of Międzyrzeki Strict Nature Reserve in the Roztocze National Park was to show new sites of rare and species new to Poland from the Kobayasiella genus (K. okadae (Skvortzov) Lange-Bert., K. tintinnus Buczkó, Wojtal & Jahn) with regard to morphological and ecological characteristics. Chemical parameters show that investigated habitats are poor and oligotrophic with a low content of chlorides, sulfates and nitrates. K. okadae, K. subtilissima (Cleve) Lange-Bert. and K. tintinnus were found in the studied area. The authors suggest the use of synonym Navicula hoeflerii Cholnoky for the Kobayasiella okadae. LM and SEM images were used in the analysis of the material.

This paper presents first polish site of Luticola frequentissima Levkov, Metzeltin & Pavlov, with morphological and ecological characteristics. The species was found in samples collected from flowing waters and soils within the area of the Bieszczady National Park and the Magura National Park. In south-eastern Poland a low number of Luticola frequentissima cells occurred in small shaded streams. It was most frequently observed in aerophitic places (shallow and drying watercourses) and in soils. In the studied samples, apart from those cells with typical dimensions, much smaller and narrower cells with a higher number of striae were found in comparison to those in the currently available literature.
