Introduction. Although Madagascar is known for its unique fauna and vascular flora, the country’s bryophyte flora in contrast is understudied and under collected. Arising from a bryophyte collecting expedition undertaken in May–June 2016, this paper describes a new species of simple thalloid liverwort, Fossombronia isaloensis, from Madagascar. Methods. Morphological traits across specimens were reviewed

Introduction. This study investigated the ecology of two boreal-montane bryophytes, the saxicolous moss Bartramia halleriana and the epixylic liverwort Crossocalyx hellerianus, at the edge of their ranges, in oceanic deciduous woodland in Wales. Methods. The study site comprises two adjoining woodlands, Allt Penyrhiw-iar (canopy trees ca. 100 yr old) and Allt Rhyd Groes (ca. 200 yr), Carmarthenshire

Introduction. The tiny moss Microhypnum sauteri is widely distributed in Europe being recorded from 14 countries, but it seems to be relatively uncommon everywhere and is on the Red List in seven of these countries. The sites in Norway are the closest populations to this new find in Scotland. Methods. A specimen was collected during a visit to Assynt in West Sutherland in April 2019, during a survey

Introduction. Currently there are two species of Oncophorus recorded in Britain O. virens (Hedw.) Brid. and O. wahlenbergii Brid., both uncommon species of wet, upland sites which are at least moderately calcareous. In a revision of Scandinavian material, Hedenäs divided O. virens into two species, O. virens and O. integerrimus, and described two further species, O. elongatus and O. demetrii previously

Introduction. This study investigated the ecology of Pallavicinia lyellii in a mire habitat dominated by Molinia caerulea, including potential abundance, frequency of sexes and sporophytes, and characteristics of the light climate beneath the herbaceous canopy. Methods. Within the study site (Cors Fochno, Wales, UK), P. lyellii was surveyed in March 2020. Abundance was measured as counts of colonies

Introduction. Bryological knowledge of the mountains of mainland Greece remained very fragmentary until the later part of the twentieth century, but increased exploration in recent years has begun to document the flora and produced significant records. Methods. As part of ongoing studies on the Greek bryophyte flora, the author, accompanied by Marko Sabovljević, visited four mountains in Northern Greece

ABSTRACT 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 compared with previous European checklists, and

Introduction. Further results are published from the British Bryological Society’s expedition to Mulanje Mountain, Malawi, 13 June–1 July 1991. Results. Records of 54 bryophyte taxa are presented, comprising 18 liverworts and 36 mosses, not counting Philonotis sp. and the possible new subspecies of Sphagnum. Twenty-nine taxa are new to Malawi.

Introduction. Dumortiera hirsuta is rare in Europe, occurring in the UK at the northern edge of its world range. This study investigated its status and ecology in England. Methods. A detailed search was made for D. hirsuta at all sites where it has been reported in England since 1841. Number of occupied 1 m grid cells was recorded and interpreted as ‘individual-equivalents’. Habitat and community composition

Introduction. Physcomitrium eurystomum is rare in Europe and threatened with extinction. This study investigates its status and ecology in Britain. Methods. A detailed search was made for P. eurystomum at all sites where it has been reported in Britain, plus four other locations nearby. Geographic coordinates of colonies were recorded with GPS units and used to derive counts of occupied Ordnance Survey

Introduction. Bryophyte diaspore banks are virtually ubiquitous in soil environments but remain poorly known and rarely given attention during conservation planning. This study investigates the frequency and composition of bryophyte diaspore banks of coastal dune slacks and considers conservation implications. Methods. A total of 327 soil samples was collected from 28 slacks at eight coastal dune systems

Introduction. The Plagiothecium flora of Myanmar is revised based on recent collections by G. Miehe and colleagues. Methods. Specimens were studied in the herbarium, and a review of relevant type material was undertaken. Key results and Conclusions. We recognise six species from Myanmar, of which two (Plagiothecium nemorale and P. paleaceum) were previously known, and four (P. euryphyllum, P. handelii

Introduction. Within Racomitrium Sect. Racomitrium, several species are distinguished in the Southern Hemisphere, but only the variable R. lanuginosum (Hedw.) Brid. exists in the north. Plants deviating from the common R. lanuginosum phenotype in leaf orientation and in almost entire or weakly dentate hair-point margins suggest that more than one species may exist in this region. Methods. Sixty-five

Introduction. During an investigation into the world-wide distribution of Anthoceros caucasicus Steph., we examined a voucher collected from Sierra Leone by A. J. Harrington in 1966 and subsequently studied by E. W. Jones. Methods. Based on spore observations using light and scanning electron microscopy we found that three Anthocerotophyta taxa were present in this mixed collection. Key results. We

Introduction. Frullania Raddi is one of the largest genera of liverworts, and the number of accepted names is still fluctuating as a result of ongoing revisionary work. Specimens, believed to be F. stylifera, an eastern North American endemic, had been collected in several remote regions in both the European and Asian parts of Russia. Methods. To confirm the identity of the Eurasian specimens they

Introduction. While revising material of South American Syntrichia for a worldwide revision of the genus, one specimen collected in Aysén (Chile) did not match the concept of any of the species known in the genus. Here we present our argument for recognising this moss as a new species and its differentiation from other closely related taxa. Methods. About 3500 specimens from South America belonging

Introduction. Leptoscyphus cuneifolius has a very limited distribution in Europe and is threatened with extinction in several regions. This study investigates its ecology at Coed y Rhygen, the most important site in Wales. Methods. GPS-based surveys documented the distribution of L. cuneifolius within the study site. Hillshade analysis was used to investigate preference for topographic locations in

Introduction. Dicranum undulatum has been lost from many sites due to destruction of peatlands. This study investigates its status and ecology at the last surviving location in southern Britain. Methods. The study site, Fenn’s, Whixall, Bettisfield, Wem and Cadney Mosses, is one of the largest lowland raised bogs in Britain. Distribution and abundance of Dicranum undulatum was documented with GPS-based

The gravitropism of caulonemata of Pottia intermedia is described and compared with that of other mosses. Spore germination produces primary protonemata including caulonemata which give rise to buds that form the leafy moss plant, the gametophore. Primary caulonemata are negatively gravitropic but their growth and the number of filaments are limited in the dark. Axenic culture of gametophores results
