In a course of a study of bryophyte diaspore bank in the Rostov Botanical Garden (Russia), two common and one rare species (Acaulon triquetrum) were obtained. Plants of the latter species grown in culture did not possess any of the important diagnostic characters, which are usually seen in nature. However, a detailed study of leaf margin structure allowed us to identify these plants for sure. Diagnostic characters of A. triquetrum and its differentiation from the second species of the genus known in Russia are discussed.

Herbarium samples of Moerckia hibernica were revised in KPABG, LE and H. Most of the c. 70 samples observed are in fact M. flotoviana that was treated as a forma of M. hibernica for a long time. It was shown that M. flotoviana is more widespread than M. hibernica. Distribution map is presented on the basis of reliable literature records and studied specimens. The identification key for the genus Moerckia as well as detailed description of M. flotoviana and its diagnostic features are provided.

SEM observations of sculpture of spore wall of the genus of Riccia enabled new appraisal of old Riccia herbarium samples. Riccia beyrichiana, R. cavernosa, R. crinita, R. erinacea are new to Ukraine. On the other hand, Riccia ciliata and R. crystallina previously reported from Ukraine, have not been confirmed. New distribution data for Riccia bifurca and R. glauca are also provided.

The annotated list of hepatics in surroundings of Lazarevskoe contains 42 taxa on specific / infra-specific level. 200 specimens were collected and identified by the authors.  Frullania fragilifolia, Porella arboris-vitae var. killariensis,  Radula complanata var. alpestris are new to Caucasus. Calypogeia arguta and  Pellia epiphylla are new to the Russian part of Caucasus. Six species are reported for the first time from the Sochi National Park. Two species of the European Red Data Bookand five species included in the Red Data Book of the Krasnodar Territory were recorded.

As a result of bryoflora inventory of mine dumps in Chervonograd industrial coal mining region 38 species of mosses belonging to two orders of Marchantiophyta (3 families, 3 genera, 3 species) and Bryophyta (15 families, 24 genera, 35 species) were found.For the investigated territory 7 rare species of mosses have been determined. Firstly, Campylopus introflexus and Pohlia sphagnicola have been discovered for bryoflora of Ukraine on the dumps of mine “Nadija” (Sosnivka of Lviv region). The results of complex analysis of devastated territories bryoflora and characteristics of its structure have been provided.

49 bryophytes species belonging to 2 divisions, 3 classes, 8 orders, 17 families, 32 genera have been found on the territory of sulphur mining dump. Taxonomic, ecological and biomorphological structure of bryophytes have been analyzed, their life strategies have been determined. Seasonal changes in the projective cover and biomass of dominant mosses species have been investigated. The obtained data testify the important role of bryophytes in restoring vegetation cover on the devastated territories of sulphur extraction.

34 species of mosses found in the vicinity of the four companies of Nikolaev (Ukraine). They grow mostly in the wood stands of different age and composition as well as settle on anthroposubstrates. Most of the mosses live on the soil ecotopes (23 species). Specific features of the moss flora, in comparison with other local bryophyte flora of the steppe zone, is a fairly large number of multi-zone (cosmopolitan) bryophytes (29.4%) and small one of arid species (11.4%), almost the same number of monoecious and dioecious species, the dominant representatives of the factions synanthropic mosses (gemiapofitov, eventapofitov). The investigated mosses implement the life strategies of coenotical and ecotopic briopatients and pioneer brioexplerents.

The results of the research into Bryophyte flora diversity of fortification constructions in Grodno district (Grodno fortress, Molotov Line, northwest Belarus) are represented. The features of taxonomical, ecological and geographical structure of the Bryophyte flora were stated. The comparison of Bryophyte species in florogenetical aspect was carried out, first of all for the species of mountain origin. The comparative analysis of the bryoflora genesis of Grodno fortifications and the Carpathians bryophyte flora (as a depot of the appropriate species) was carried out.
