ABSTRACT Introduction During examination of assorted mosses sent for identification, a specimen of Vinealobryum (Pottiaceae) from Iceland was found to be unlike other species of the genus. Methods Standard microscopical analysis was carried out, accompanied by consultation of published literature and re-examination of permanent microscope slides made during prior studies. Key results and conclusions The species Vinealobryum islandicum, sp. nov., is here described as new because it proved distinct from congeners by the crowding of its plants in a dense turf, and its fragile stems, leaves isomorphic along the elongate stems, fragile at midleaf or above, and 4- to 8-celled gemmae that are spherical or with bulging cells on short stalks on adaxial costa at the leaf apex.
在对送去鉴定的各种苔藓进行检查时，发现冰岛的一种vinalobryum (Pottiaceae)标本与该属的其他物种不同。方法进行标准的显微镜分析，查阅已发表的文献，重新检查先前研究中制作的永久显微镜载玻片。主要结果和结论岛葡萄属(vinalobryum islandicum, p. nov.)在这里被描述为新物种，因为它的植物在茂密的草皮中拥挤，其脆弱的茎，沿细长茎的叶片同形，叶中部或上部脆弱，叶顶端短茎上的4- 8细胞球形或膨出细胞。

Carl Müller of Halle (1874) reported on some mosses collected in the Pacific Islands (including Samoa) between 1862 and 1873 by Dr E. O. Graeffe. From among these specimens he described several new species, some of which were named in honour of the collector; these included Calymperes graeffeanum Müll.Hal. Unfortunately, Müller’s herbarium, containing the primary set of the original material (holotypes) on which his new species were based, was largely destroyed in Berlin (B) during the Second World War. However, duplicate specimens of at least some of Müller’s original material had been distributed to several of his contemporaries and now reside in various herbaria in Europe and North America. In the absence of original material in Müller’s own herbarium, necessary typification of his new species must be resolved from among these extant duplicates (Turland et al. 2018, Arts 9.3 and 9.12). The typification of C. graeffeanum requires such resolution. Calymperes campylopodioides Müll.Hal. ex Besch. was described from Cameroon (Bescherelle 1895). Although sometimes confused with C. palisotii Schwägr., it is conspecific with C. graeffeanum (Ellis 2001) and represents a rare African occurrence of the latter. Since it was placed in synonymy with C. graeffeanum (Ellis 2001), original material of C. campylopodioides has come to light, which requires the entity to be more precisely typified. This nineteenth-century record of C. graeffeanum constitutes its most westerly occurrence, and a further, and more recent record from Cameroon (Thompson & Rawlins 1630, MO), collected in 1984, confirms its persistence then, in West Africa. The West African occurrence of C. graeffeanum is disjunct from its otherwise largely Indo-Pacific distribution range; the closest occurrence of the species eastward from Cameroon is a single record from Tanzania, reported by Orbán (1995). Records of C. graeffeanum becomemore frequent eastwards from the islands of the Indian Ocean and through southern India and Malesia; the range of the species extends further eastwards across the Pacific islands, as far as Pitcairn Island (Ellis 1988). Calymperes graeffeanum has been reported as far north as southeastern China (Reese and Lin 1991; Lin and Reese 2001), and its most southerly occurrence is in tropical Australia (Ellis 1988; Reese and Stone 1995).

ABSTRACT Introduction Riella Mont. is unusual among bryophyte genera because its species have an ephemeral habit and grow submerged in fresh or brackish waters. Most species show fragmented distribution areas and have few known populations and are thus of conservation concern. The flagship Mediterranean species R. helicophylla (Bory & Mont.) Mont. has recently been taxonomically reassessed, and most populations have been placed in a new species, R. macrocarpa (P.Allorge) Puche, Segarra-Moragues, Sabovlj., M.Infante & Heras. Here we describe the development of nuclear microsatellite markers for R. macrocarpa with the aim of characterising the population genetic dynamics of this species of conservation concern, and we report their potential use in other species of the genus. Methods Nuclear microsatellite markers were isolated from 454 genomic libraries and amplification parameters optimised for the set of loci finally selected. Key results and conclusions Nine microsatellite loci were characterised and amplified a total of 53 alleles in a sample of 120 individuals from four populations, having a mean of 5.89 alleles per locus. Unbiased genetic diversity for the polymorphic loci within populations ranged from 0.067 to 0.791. Cross-species transferability assayed in six other species of Riella covering reproductive and taxonomic diversity in the genus showed transferability success rates ranging from 77.8% to 100%, with 33.3% to 57.1% of the successfully transferred loci being polymorphic within species. These markers will be useful for studying population genetic diversity and structure and will contribute towards better conservation management of populations of R. macrocarpa and other species of Riella.

During revision of Polytrichum commune Hedw. and related taxa worldwide as part of an investigation undertaken during work for a Ph.D. thesis by the first author, a large number of historic and type specimens of taxa described under the genus Polytrichum were borrowed from various herbaria to help clarify the correct application of names. This process permitted the study of many potential and known type specimens that had not previously been critically examined. Numerous names were assigned to taxa now recognised within the recently revised Polytrichum commune complex (Kariyawasam 2021). However, one Polytrichum binomial for which original material, preserved in the Berlin herbarium (B), had apparently not previously been recognised or studied is that of P. transvaaliense Müll.Hal. At first sight this specimen clearly did not belong in Polytrichum as now recognised, but looked much more likely to be a member of Pogonatum, as was quickly confirmed. This binomial has not been dealt with in the revisions of De Sloover (1986) or Hyvönen (1989). It is listed under Polytrichum in the checklist of O’Shea (2006), but without any further comments. Using Hyvönen’s key to Pogonatum worldwide, the type specimen clearly falls within the circumscription of Pogonatum capense (Hampe) A.Jaeger, a relatively widespread species in South Africa and also reported from Angola, Zimbabwe, Madagascar and Mauritius (De Sloover 1986). As a later name, Polytrichum transvaaliense Müll.Hal. can now be lectotypifiied and relegated to the synonymy of that species, as detailed below. This adds to the five synonyms of Pognatum capense already listed by Hyvönen (1989).

ABSTRACT Introduction In the context of a taxonomic revision of the tribe Pleuroweisieae in South America, we studied a specimen of Hymenostylium that did not match any previously known species of this genus in America. Here we present our arguments for recognising this moss as a new species. Methods The morphology of the potential new species was compared with that of the species of Hymenostylium presently recognised. A phylogenetic analysis based on the nuclear ITS and plastid rps4 regions was performed to investigate relationships between the new species and closely related taxa. Key results and conclusions Based on morphological and molecular data, we describe this new species from Brazil, Hymenostylium chapadense M.J.Cano & J.A.Jiménez. The species is strikingly distinguished by a stem with central strand and hyalodermis, oblong-ligulate to oblong-elliptical leaves that are when dry slightly crisped in the upper part and usually constricted just above the base and recurved on one side in the lower third, with uni- to bistratose margins, obtuse apex, costa wide and ending below the apex or percurrent with ventral and dorsal surface cells of the costa differentiated as an epidermis, and middle laminal cells usually with a simple, coarse, central papilla. Our molecular study placed H. chapadense as sister to H. hildebrandtii (Müll.Hal.) R.H.Zander. Possible confusion with the latter species and other closely related taxa is discussed. A key to the South American species of Hymenostylium is provided.

ABSTRACT Introduction Half a century since the creation of the International Association of Bryologists, we carried out a review to identify outstanding challenges and future perspectives in bryology. Specifically, we have identified 50 fundamental questions that are critical in advancing the discipline. Methods We have adapted a deep-rooted methodology of horizon scanning to identify key research foci. An initial pool of 258 questions was prepared by a multidisciplinary and international working group of 32 bryologists. A series of online surveys completed by a broader community of researchers in bryology, followed by quality-control steps implemented by the working group, were used to create a list of top-priority questions. This final list was restricted to 50 questions with a broad conceptual scope and answerable through realistic research approaches. Key results The top list of 50 fundamental questions was organised into four general topics: Bryophyte Biodiversity and Biogeography; Bryophyte Ecology, Physiology and Reproductive Biology; Bryophyte Conservation and Management; and Bryophyte Evolution and Systematics. These topics included 9, 19, 14 and 8 questions, respectively. Conclusions Although many of the research challenges identified are not newly conceived, our horizon-scanning exercise has established a significant foundation for future bryological research. We suggest analytical and conceptual strategies and novel developments for potential use in advancing the research agenda for bryology.

ABSTRACT Introduction Codonoblepharon forsteri (Dicks.) Goffinet is a rare epiphytic moss characteristically associated with water-filled holes in trees. We reviewed its range and population and assessed effects of climate change. Methods An inventory of sites from where Codonoblepharon forsteri has been recorded was compiled. Extent of occurrence (EOO) and area of occupancy (AOO) were calculated. Population size was estimated, treating an occupied tree as an ‘individual-equivalent’ of the moss. Climatic conditions of the species’ current distribution were characterised, and an ensemble model of its distribution was generated. The latter was projected onto present and future climatic layers. Key results Codonoblepharon forsteri has been recorded from 19 countries and 205 sites in Europe, North Africa and Southwest Asia. It has been undergoing an overall decline. Most sites have few occupied trees, and a world population of 1000–10,000 individual-equivalents is estimated. Model projections suggest that the species will experience a range increase of +0.36–0.65 by 2050 and +0.35–0.68 by 2070, especially in its northwest range, particularly across France and the UK. Range loss is predicted to be between –0.20 and –0.39 in 2050 and –0.21 and –0.65 in 2070, affecting the driest areas of the current range around the Mediterranean, especially in North Africa. Conclusions Codonoblepharon forsteri has a relatively large EOO but relatively small AOO, probably due to habitat specialism. A major reason for recent declines appears to be widespread abandonment of traditional ‘pollarding’ of trees. The potential climatic range of the species will shift significantly northwards over the next few decades.
