Article
Introduction. We report the results of an international bryological expedition to the Khamar- Daban mountain range in Russian southern Siberia. The novel approach of integrative floristics is introduced here as a method of surveying the flora of a region by using a combination of morphological and molecular evidence to identify and verify unexpecte...

We present an integrative molecular and morphological study of subaquatic representatives of the genus Pseudohygrohypnum (Pylaisiaceae, Bryophyta), supplemented by distribution modelling of the revealed phylogenetic lineages. Phylogenetic analyses of nuclear and plastid datasets combined with the assemble species by automatic partitioning (ASAP) al...
Article
Sporoderm development in Andreaeobryum is studied and confirned to be similar to that in Andreaea in having no lamellate structure in the exine. The formation of the outer layers of the spore wall, external to the intine, proceeds by the accumulation of sporopollenin granules originating within the special wall of the sporocyte. Despite the outermo...

The Skvortsov Herbarium of the Tsitsin Main Botanical Garden, Russian Academy of Sciences (MHA) in the 1945-1980s dealt with vascular plants and only scattered occasional collections of bryophytes and lichens were accumulated there without special arrangement. Since the late 1980s, the bryophyte studies in the MHA Herbarium became permanent and sev...

Anacamptodon latidens is discovered in the Russian Caucasus as a species new to the territory of Europe as the latter is defined in recent Checklists. Previously these Caucasian specimens were reported as A. splachnoides, hence the latter species is excluded from moss flora of Russia, although it occurs in Georgia in the Caucasus close to the Russi...

Article
The moss fossil records from the Paleozoic age to the Eocene epoch are reviewed and their putative relationships to extant moss groups discussed. The incomplete preservation and lack of key characters that could define the position of an ancient moss in modern classification remain the problem. Carboniferous records are still impossible to refer to...

The Khasurty locality (Lower Cretaceous of Transbaikalia, Russia) is one of the largest fossil insect sites in the region. Over the entire period of study, more than 6000 insect imprints have been collected here, representing 16 orders and 130 families. Dipterans, aphids and hymenopterans are the most common forms here, the most diverse taxa are Di...
Article
Tayloria rudolphiana is documented in Altai Mountains, Russia as the first occurrence in North Asia. Previously this species was known in a limited range in Central Europe in Austria, Germany and Switzerland, where it at present is critically endangered to vulnerable. There are two disjunctive localities in China, a recent one in Hubei and a hundre...

Molecular phylogenetic reconstructions of Rhabdoweisiaceae based on plastid (trnS-rps4 and trnL-F) and mitochondrial (nad5) DNA sequences and a comprehensive taxon sampling were performed, including 15 out of 16 genera currently attributed to the family, taxa recently found belonging to Rhabdoweisiaceae and expanded outgroups from related families...

Article
Previous morphological studies and molecular phylogenetic reconstructions resolved Discelium in the diplolepideous-opposite peristome group of mosses among the early-diverging mosses with arthrodontous peristomes. However, sporophyte development in Discelium differs from that of the other ‘diplolepideous-opposite’ families, Funariaceae and Encalypt...
Article
Premise: The Sphagnum recurvum complex comprises a group of closely related peat mosses that are dominant components of many northern wetland ecosystems. Taxonomic hypotheses for the group range from interpreting the whole complex as one polymorphic species to distinguishing 6-10 species. The complex occurs throughout the Northern Hemisphere, and...

The Chilean endemic genus Costesia belongs to the Gigaspermaceae, one of the most basal groups of arthrodontous mosses. While none of the species in this family has a peristome, earlier stages of sporophyte development often disclose its basic structure. The study of Costesia sporophytes at the early stages of development was conducted to identify...

We present a description of the new species Rhynchostegium occultum from central Chile, including illustrations, a distribution map, and preliminary molecular data that supports its taxonomic placement. The new taxon is restricted to coastal relict forests of central Chile. An overview of the Chilean taxa of Rhynchostegium, and a key for local spec...

Moss paraphyllia, the trichome-like or foliose structures on moss stem surfaces, are usually treated as epidermal outgrowths. However, in some taxa of the moss families Leskeaceae, Neckeraceae, and Amblystegiaceae their distribution along the stem is consistently correlated with parts of the stem surface near branch primordia. In other moss familie...

Introduction. Following on from work on the European bryophyte Red List, the taxonomically and nomenclaturally updated spreadsheets used for that project have been expanded into a new checklist for the bryophytes of Europe. Methods. A steering group of ten European bryologists was convened, and over the course of a year, the spreadsheets were compa...

Result of an extensive moss study of earlier nearly unexplored areas of the northeastern part of the Subpolar Urals, namely Khulga River Basin is presented. An annotated list of mosses is compiled based on the identification of 1200 specimens collected in the Khulga River Basin (60.45–65.20°N, 60.42–62.20°E). The river starts at the border between...

We report here the new, highly disjunct Asian occurrences for two Hymenostylium species, which have so far only been known from Europe. Hymenostylium xerophilum is newly reported from Oman and eastern Yakutia, while the other species, H. gracillimum was found among herbarium material collected at the shore of Lake Baikal in southern Siberia. While...
Article
The taxonomy of pleurocarpous mosses has long been based on a few key characters such as the presence or absence of a single costa or the posture of the leaves. Molecular analyses performed in the past two decades have often challenged the traditional familial and generic delimitations, as these simple characters have evolved repeatedly. For nearly...

The moss family Hylocomiaceae is studied for the generic level taxonomy within a molecular phylogenetic approach. We confirm segregating of the species formerly known as Rhytidiadelphus triquetrus to Hylocomiadelphus Ochyra & Stebel from the genus Rhytidiadelphus . Hylocomiadelphus forms a clade with Loeskeobryum and Meteoriella , sharing with both...

Molecular phylogenetic analysis supported an isolated position of Neckera polyclada within the "Pinnatella-clade" of the family Neckeraceae, thus it is segregated in a new monospecific genus Enrothia. The closest of relatives of Enrothia the obtained reconstructions, Neckera warburgii, N. himalayana, and Curvicladum kurzii never form a supported cl...

Molecular phylogenetic analysis supports the position on the species known as Neckera konoi in the genus Forsstroemia, therefore it is transferred to this genus with a new combination, F. konoi (Broth.) Enroth, Fedosov & Ignatov. Molecular data also confirm the position of F. stricta Laz. described from the Russian Far East in F. producta, a pantro...

A molecular phylogenetic analysis based on nuclear ITS, plastid trnS-F, rpl16, atpB-rbcL and mitochondrial nad5 revealed polyphyly in the genus Anomodon, and therefore its segregation into four genera is proposed. The largest clade includes A. viticulosus, the generitype of Anomodon, and all species with a broadly rounded leaf apex, including those...
