Two species of Scapania (S. magadanica and S. spitsbergensis) are newly reported for the Kamchatka Peninsula from the Alney-Chashakondzha Massif (Central Kamchatka). New records of the recently described S. magadanica are the first outside the Magadan Province and expand its known distribution. Both species occur on Kamchatka Peninsula in areas of current glaciations or areas where periglacial processes were common in relatively recent past. These species were found in Kamchata without sporophytes, and in general produce sporophytes quite rarely.

Pottiodicranum gen.nov. is described based on an inclusion in Late Eocene Rovno amber.The fossil is characterized by an acrocarpous habit, common for many genera of haplolepideous mosses, but differs from all known Paleogene amber fossils of acrocarpous mosses in the presence of several high solid papillae above the lumen of the lamina cells.The papillae are present on the dorsal and ventral side of the lamina and resemble modern Pottiaceae species.However, Pottiodicranum papillosum has a striate dorsal costa surface consisting of low ridges similar to those of some species of Dicranaceae s.l., especially Campylopus and Dicranum.However modern Dicranaceae lack this kind of papillae, while Pottiaceae may have lamellae on the ventral side of the costa, but not on the dorsal side.Thus the Eocene moss fossil possesses a unique combination of characters and apparently belongs to an extinct group of Dicranidae, while the family relationships remain unclear. РезюмеИз познеэоценового ровненского янтаря описан новый род мхов, Pottiodicranum gen.nov.В целом по своему строению он сходен с верхоплодными мхами, особенно представляющими группу гаплолепидных мхов, или подкласс Dicranidae.В то же время, он отличается от всех прочих верхоплодных мхов, извеcтных из янтарей палеогеновых отложений, наличием нескольких высоких цельных папилл над просветом клеток листа.Папиллы развиты как на дорсальной, так и на вентральной сторонах листа и весьма напоминают по своему строению папиллы многих современных родов семейства Pottiaceae.В то же время, Pottiodicranum papillosum, единственный вид рода, имеет на дорсальной стороне жилки гребни, а также ясную продольную исчерченность, известную у современных мхов семейства Dicranaceae s.l., особенно у Campylopus и Dicranum.В то же время у представителей Dicranaceae не бывает таких папилл, а в семействе Pottiaceae неизвестны пластиночки или гребни на дорсальной стороне листа.Хотя все признаки Pottiodicranum известны в подклассе Dicranidae, их необычная комбинация делает род уникальным.

A result of bryological survey in the Burdur province in Turkey (Southwest Anatolia), a total of 247 bryophytes belonging to 99 genera (18 liverworts and 81 mosses) and 45 families were determined from 185 different localities.Of these, 26 taxa are liverworts and 221 taxa are mosses.Among them, Orthotrichum sordidum and Syntrichia fragilis are recorded for the second time in Turkey.Also, all taxa are new to Burdur province.Резюме В результате бриологического обследования 185 пунктов в провинции Бурдур в Турции (Юго-Западная Анатолия) выявлено в общей сложности 247 видов мохообразных из 99 родов и 45 семейств, в том числе 25 печеночников из 18 родов и 221 мох из 81 рода.Находки Orthotrichum sordidum и Syntrichia fragilis являются вторыми местонахождениями в Турции.Все виды приводятся впервые для провинции Бурдур.

To determine bryophyte diversity of Ordu region, investigation materials were collected from 310 different localities between 1 October 2013 and 1 October 2015 in the study area. The taxonomic survey of Ordu yielded one species of Anthocerotophyta, 51 taxa of 25 families of Marchantiophyta and 365 taxa of 43 families of Bryophyta. Among these taxa, Thamnobryum coreanum (Cardot) Nog. & Z. Iwats. appears to be new to bryophyte Flora of Turkey. All taxa are new records for the Ordu Province.

Didymodon australasiae is reported for the first time from Russia. It was collected in the south of Zabaikalsky Territory, in Sokhondinsky Nature Reserve. This locality extends northward its known distribution in Eurasia. Description, illustrations and ecological data based on Siberian material are provided.

Solenostoma sanguinolentum (Griff.) Steph. and related species are discussed based on study of type and other available materials. The species status of S. marcescens (Mitt.) Bakalin is confirmed and S. longii Bakalin sp. nov. is described. The new species is characterized by pink coloration, prostrate to ascending growth and not or barely decurrent leaves. The photographs made from type materials are provided.

Annotated list of 145 mosses collected on the Tardoki-Yani Mt is presented. Annotations provide data on altitudinal distribution of each species, ecology and accompanying species. The specificity of the forest belt in the area comprises the addition of hemiboreal East Asian species to the generally boreal species composition. Brachythecium garovaglioides is newly found in Russia. Other interesting species include Oedipodium griffithianum, Pohlia vexans, Sphagnum alaskense and two tentatively undescribed species of the genera Dicranum and Seligeria; the latter are supplied with additional comments. Twenty nine species are newly reported for the Sikhote-Alin; some of these species have mainly arctic-alpine distribution and are found on the Tardoki-Yani Mt quite far from the area of their continuous distribution.

The purpose of this research is to correlate distribution of Sphagnum species with local climatic factors in the East European Plain. Six species of Sphagnum from section Sphagnum, i.e., S. magellanicum, S. centrale, S. palustre, S. papillosum, S. austinii, and S. affine were selected. The graded data on their abundance and the species number for 138 localities were mapped into unit squares of 1010 km by using GRID coverage, to construct several delineated zones of occurence/ abundance. For analysis, the matrix was augmented by extended data from the BIOCLIM database. Regression analysis revealed strong correlation between species distribution and temperature, while abundance of the species showed high correlation with maximum relative humidity in two months, August and September, being especially high for most common species, S. magellanicum (0.85 and 0.83) and S. centrale (0.81 0.76). Distribution area of Sphagnum palustre is restricted by precipitation in the whole warm part of the year, while Sphagnum papillosum avoids regions with low relative humidity in early summer. The local number of species correlates with relative humidity in summer. The developed technique demonstrates a possible way of applying the climatic data to the analysis of the bryophyte distribution in extensive territories.

Spheric to ovoid or bulb-like brood bodies are found in Upper Palaeozoic mosses of the order Protosphagnales. They developed on stems and leaf costae, and putatively also on the apical parts of leaves. Their surface was smooth or, more commonly, rough due to short rhizoid initials densely covering their surface all around. It seems that rhizoids developed especially after brood bodies started growth, becoming larger and then forming stem. Rhizoids on brood bodies and on stems growing out of them have oblique cell walls, characteristic to all other mosses. They definitely belong to species of Protosphagnales, wherefrom they were not reported earlier. However, as the taxonomy of the genera of protosphagnalean mosses is based primarily on leaf characters, a new form-genus Bulbosphagnum is described to accommodate numerous brood bodies themselves and also brood bodies with leafless stem bases. In the extant flora, the most similar brood bodies are known in Oedipodium where they also may form on various parts of plants and have similar shape and size, although differ in fewer rhizoid production as compared with Bulbosphagnum.
