IntroductionMethodsKey results and conclusionsLocated on the extreme edge of its range, Didymodon cordatus is exceptionally rare in Britain and is considered a priority for conservation. In the present study, its current population status and ecology were investigated.All previously known locations for the species were surveyed, plus other potential locations nearby. Abundance was measured in terms of ‘individual-equivalents’, defined as an occupied 1  m grid cell. Geographical coordinates of each individual-equivalent were recorded with a GPS unit. Habitat and community composition were recorded by relevés.Didymodon cordatus continues to survive at its only location in Britain, at Saunton Down, North Devon, including a length of nearby coastal cliff from where it has been known since 1916 and an adjacent roadside bank from where it has been known since 1962. No other locations were found. It occupies open, dry, calcareous and thermophilous habitat, together with a diverse assemblage of other acrocarpous mosses. While the species is particularly associated with loess soils in continental Europe, at Saunton Down it is closely associated with soft, calcareous sandstone and thin, overlying sandy soil. Natural erosion is an important part of the occupied habitat, maintaining early successional habitat patches suitable for colonisation. A total of 102 individual-equivalents were found, and it is estimated that the entire population at Saunton Down comprises 250–1000 individual-equivalents. The habitat is generally in favourable condition and the population appears to be secure, although the species will remain vulnerable to extinction in Britain because of its extreme rarity.

Context: Although the vascular flora of Western Australia is renowned for high species diversity and endemism, very little is known about the state's moss and liverwort flora. Aims: In 1984 we conducted surveys of bryophytes in Two Peoples Bay Nature Reserve. Methods: We searched comprehensively for bryophytes at seven major habitats on the Reserve, collecting voucher specimens subsequently identified with modern literature and with the help of Australian bryophyte experts. We updated the text to reflect modern taxonomy and considering modern literature on phytogeography and hypotheses associated with OCBIL (Old, Climatically Buffered, Infertile Landscapes) theory. Key results: A total of 38 species of mosses representing 25 genera from 13 families were identified along with 10 species of liverworts representing nine genera and six families. Two moss species (Distichium inclinatum and Tortella dakinii) were previously unknown from Western Australia. Another represented a new species (Pleurophascum occidentale) in a heretofore monotypic genus, family, and order. The Pottiaceae, with 11 species, was the most diverse family of mosses. The Lepidoziaceae, with three species, was the most diverse family of liverworts. Conclusions: Lower levels of endemism in bryophytes versus vascular plants may reflect the bryophytes' capacity for wide and long-distance dispersal of spores and fragments. Bryophyte diversity and endemism may be less than on extensive OCBILs because much of the Reserve emerged from the ocean as recently as the mid-Pleistocene. Implications: This, the first listing published of bryophytes on a Reserve in WA, indicates the potential rewards for further survey of mosses and liverworts. In 1984 we searched comprehensively for bryophytes at seven major habitats on Two Peoples Bay Nature Reserve. A total of 38 species of mosses and ten species of liverworts included two moss species (Distichium inclinatum and Tortella dakinii) previously unknown from Western Australia. Another represented a new species (Pleurophascum occidentale) in a heretofore monotypic order. This, the first listing published of bryophytes on a Reserve in Western Australia, indicates the potential rewards for further survey of bryophytes. This article belongs to the Collection The Natural History of Two Peoples Bay Nature Reserve, Western Australia. [ABSTRACT FROM AUTHOR]

Pterygoneurum sampaianum (Guim.) Guim. is newly recorded in Tunisia and in France. Molecular data from French and Tunisian samples support the specific rank of P. sampaianum and allow for a clear differentiation from P. ovatum (Hedw.) Dixon in cases where the morphology appears to be transitional between the species. By including a molecular phylogenetic analysis based on the sequence data obtained from European representatives of the genus, we could re-evaluate the phylogenetic affinities of P. sampaianum which was found to be close to the recently described P. papillosum Oesau. Based on the molecularly guided identifications, we provide an amended detailed description of P. sampaianum and report on ecological and chorological details of the newly recorded specimens.

The study explored batch adsorption of Cd(II) and Pb(II) ions using moss biomass from Barbula consanguinea and Hyophila involuta, assessing removal efficiency concerning various parameters. Both moss species showed high removal rates for Cd(II) (87 % for B. consanguinea and 89 % for H. involuta) and Pb(II) (93 % for B. consanguinea and 94 % for H. involuta) from contaminated water, reaching equilibrium within 30 min. While Cd(II) removal was pH-independent, Pb(II) removal showed pH-dependence, peaking at pH 5.0–5.5. Adsorption isotherm analysis indicated that the Langmuir, Freundlich, Elovich, Sips, and Redlich-Peterson models best described Cd(II) and Pb(II) adsorption onto both moss species (except for Cd(II) adsorption onto H. involuta), with R2 > 0.98. This confirms a heterogeneous surface with both monolayer and multilayer adsorption sites. The pseudo-second-order kinetic model confirmed chemisorption on moss biomass from both species. FTIR spectra identified major binding sites such as phenols, alkaloids, amines, alkenes, nitro compounds, and low-molecular-weight carbohydrates. EDS analysis validated the bonding of Cd(II) and Pb(II) ions to the biomass surface by displacing Ca(II) ions. According to the Langmuir model, moss biomass exhibited selective adsorption, favoring Pb(II) over Cd(II). B. consanguinea showed a higher adsorption capacity than H. involuta, which is attributed to its higher negative zeta potential. This study underscores the novelty of moss biomass for heavy metal removal in wastewater treatment, highlighting its sustainability, effectiveness, cost-efficiency, versatility, and eco-friendliness.

Vinealobryum eckeliae (R.H. Zander) R.H. Zander is a poorly understood moss species native to the west coast of North America and Spain. Since its description in 2007, the number of collections in North America has more than doubled, providing valuable data regarding the species' phenology, morphology, ecology, and distribution. An analysis of 75 specimens has confirmed the plant to be dioicous with sporophytes maturing predominantly in the spring and summer. Reproductive specimens were used to produce ranges for sporophyte characters, and non-reproductive specimens were used to investigate gametophyte morphological patterns that were not previously reported. Micrographs were captured to present both gametophytic and sporophytic features of the moss. Label data extracted from the Consortium of North American Bryophyte Herbaria were used to update the species' habitat preferences and distribution. A dichotomous key to the genus Vinealobryum of California is provided. [ABSTRACT FROM AUTHOR]

Premise: To address the biodiversity crisis, we need to understand the evolution of all organisms and how they fill geographic and ecological space. Syntrichia is one of the most diverse and dominant genera of mosses, ranging from alpine habitats to desert biocrusts, yet its evolutionary history remains unclear. Methods: We present a comprehensive phylogenetic analysis of Syntrichia, based on both molecular and morphological data, with most of the named species and closest outgroups represented. In addition, we provide ancestral‐state reconstructions of water‐related traits and a global biogeographic analysis. Results: We found 10 major well‐resolved subclades of Syntrichia that possess geographical or morphological coherence, in some cases representing previously accepted genera. We infer that the extant species diversity of Syntrichia likely originated in South America in the early Eocene (56.5–43.8 million years ago [Mya]), subsequently expanded its distribution to the neotropics, and finally dispersed to the northern hemisphere. There, the clade experienced a recent diversification (15–12 Mya) into a broad set of ecological niches (e.g., the S. caninervis and S. ruralis complexes). The transition from terricolous to either saxicolous or epiphytic habitats occurred more than once and was associated with changes in water‐related traits. Conclusions: Our study provides a framework for understanding the evolutionary history of Syntrichia through the combination of morphological and molecular characters, revealing that migration events that shaped the current distribution of the clade have implications for morphological character evolution in relation to niche diversity.

The moss genus Algaria currently comprises a single species known only from the type locality. During recent bryological surveys of remnant Overberg Renosterveld patches, plants were collected that clearly belong to this genus but differ from the only known species in several critical respects. Here, we describe these as a new species. Specimens were rehydrated in the laboratory, dissected, and mounted in Hoyer's solution or polyvinyl alcohol–glycerine. Observations and measurements were made using standard stereo and compound microscopy. Spore anatomy was further investigated using scanning electron microscopy. Algaria overbergensis Hedd. & R.H.Zander is described as a new species currently known from only three localities in Overberg Rûens Renosterveld. It is readily distinguished from its only congener (Algaria natalieae Hedd. & R.H.Zander) by its rounder capsule with a domed to conical operculum, epapillose calyptra, much larger spores, and truncate leaves with a narrower border of elongate cells.

The complete chloroplast and mitochondrial genome sequences of Scopelophila cataractae (Pottiaceae, Bryophyta) are determined. The chloroplast genome is 122,290 bp with 118 genes and the mitochondrial genome is 105,607 bp with 67 genes, both genomes are circular. This study showed the S. cataractae plastome contains the smallest genome size, and a functional trnPGGG gene, relative to other pottiaceous species. Phylogenetic inferences support the sister relationship of S. cataractae to all other pottiaceous accessions.

Benthic animals and water plants species useful for devising an index to indicate the extent of Al and Cr contamination in the Kinokawa River catchment area were studied. Studies revealed that the Al concentrations in crane fly larvae (260 to 5,260 mg/kg-dry) and bryophytes (640 to 20,000 mg/kg-dry) around a closed Cu mine were about 1.5 times higher than those around a non-mine area (530 to 3,100 for crane fly larvae and 220 to 13,000 mg/kg-dry for bryophytes). Cr concentrations in dragonfly larvae around the serpentinite (3 to 30 mg/kg-dry) were about 3 times higher than those around the non-serpentinite area (0.6 to 9 mg/kg-dry). Cr concentrations in bryophytes around the serpentinite (3 to 91 mg/kg-dry) were about 1.5 times higher than those around the non-serpentinite area (2 to 53 mg/kg-dry). Al concentrations in Pottiaceae, a kind of bryophyte found around a closed Cu mine (890 to 20,000 mg/kg-dry) were about 2.5 times higher than those around a non-mine area (6,300 to 8,000 mg/kg-dry). Cr concentrations in Pottiaceae found around the serpentinite area (91 mg/kg-dry) were about 3 times higher than those around the non-serpentinite area (3 to 29 mg/kg-dry). Additionally, crane fly larvae, dragonfly larvae, bryophytes, and Pottiaceae were widely distributed as they were sampled around both contaminated and non-contaminated areas. Therefore, it was concluded that useful species for devising an index to indicate contamination included the crane fly larvae for Al, dragonfly larvae for Cr, and the bryophytes, especially Pottiaceae for Al and Cr.

A spreadsheet dealing with standard deviations allows statistical examination of continuous variables associated with paraphyly in systematics, with examples in the Pottiaceae (Bryophyta). Outlier values in taxonomic representation of distribution with the structure of (w-)x-y(-z) of continuous variables can be empirically supported. The use of the geometric mean and intuitional estimation is reexamined. Published reports of the distance between maximally distant exemplars of individual paraphyletic species in molecular cladograms in several studies were reevaluated as metadata. Levels of standard deviations were assigned with the Running Sigmas spreadsheet. A spike in width of exemplars of a paraphyletic species of a moss in the family Pottiaceae, Exobryum asperifolium, was identified as an outlier. Techniques of macroevolutionary systematics, however, assured that no different evolutionary processes were involved that may have supported an explanation of taxonomic crypsis. Instead it was found that metadata heterogeneity was the problem in that the paraphyly width of 14 molecular cladogram nodes which is evolutionarily acceptable as a clear-cut progenitordescendant lineage with no reversals.

Bryophytes are the earliest plant group on Earth. They are a fundamental component of many ecosystems around the World. Some of their main roles are related to soil development, water retention, and biogeochemical cycling. Bryophytes include liverworts, hornworts, and mosses. The sequencing of chloroplast and mitochondria genomes has been useful to elucidate the taxonomy of this heterogeneous plant group. To date, despite their ecological importance only 41 mosses mitogenomes have been deposited in the GenBank. Here, the complete mitochondria genome sequence of Pseudocrossidium replicatum, a moss of the Pottiaceae family isolated in Tlaxcala, Mexico, is reported. The mitochondrial genome size of P. replicatum comprises 105,495 bp and contains the groups of genes described for other bryophytes mitogenomes. Our phylogenetic analysis shows that during the evolution of the mosses’ mitogenome, nad7, rps4, rpl16, and rpl10 genes were lost independently in several lineages. The complete mitogenome sequence reported here would be a useful tool for our comprehension of the evolutionary and population genetics of this group of plants.

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. Standard microscopical analysis was carried out, accompanied by consultation of published literature and re-examination of permanent microscope slides made during prior studies. 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.

PREMISE: Desiccation tolerance (DT) is a widespread phenomenon among land plants, and variable ecological strategies for DT are likely to exist. Using Syntrichia caninervis, a dryland moss and model system used in DT studies, we hypothesized that DT is lowest in juvenile (protonemal) tissues, highest in asexual reproductive propagules (gemmae), and intermediate in adults (shoots). We tested the long‐standing hypothesis of an inherent constitutive strategy of DT in this species. METHODS: Plants were rapidly dried to levels of equilibrating relative humidity (RHeq) ranging from 0 to 93%. Postrehydration recovery was assessed using chlorophyll fluorescence, regeneration rates, and visual tissue damage. For each life phase, we estimated the minimum rate of drying (RoDmin) at RHeq = 42% that did not elicit damage 24 h postrehydration. RESULTS: DT strategy varied with life phase, with adult shoots having the lowest RoDmin (10‒25 min), followed by gemmae (3‒10 h) and protonema (14‒20 h). Adult shoots exhibited no detectable damage 24 h postrehydration following a rapid‐dry only at the highest RHeq used (93%), but when dried to lower RHs the response declined to <50% of control fluorescence values. Notably, immediately following rehydration (0 h postrehydration), shoots were damaged below control levels of fluorescence regardless of the RHeq, thus implicating damage. CONCLUSIONS: Life phases of the moss S. caninervis had a range of strategies from near constitutive (adult shoots) to demonstrably inducible (protonema). A new response variable for assessing degree of DT is introduced as the minimum rate of drying from which full recovery occurs. [ABSTRACT FROM AUTHOR]

Background and aims: The bryophyte flora of Argentina is currently under study, nevertheless, there are still extensive areas unexplored, such as Santiago del Estero with only three records of bryophytes to the entire region. The aim of this work was to contribute to the knowledge of the moss flora of Santiago del Estero province, through the collection of samples in Copo National Park and surroundings. M&M: The specimens were collected in the Copo National Park and surroundings, processed and studied according to traditional techniques for bryophytes. Microscopic characters were observed with stereoscopic and light microscopy. A list of the species found is presented, with comments on the differentiating characters, habitat and distribution. Results: The following moss taxa were found to be new records for the province: Aloina rigida; Dimerodontium balansae; Didymodon umbrosus; Fabronia ciliaris; Macrocoma tenuis subsp. sullivantii; Pseudocrossidium arenicola; P. linearifolium; Stereophyllum radiculosum; Syntrichia chisosa, Trichostomum brachydontium and Venturiella glaziovii. The range of distribution of Tricherpodium beccarii is extended to the northeast of the province. Conclusions: Eleven species and one subspecies, distributed in ten genera and five families, are newly reported for the province of Santiago del Estero. The range of distribution of one species is extended to the northeast of the province. These first studies highlight the unexplored floristic richness of the region and its vulnerability due to the accelerated advance of the agricultural-livestock border.

In the course of a worldwide revision of the genus Syntrichia, we identified problems in the circumscription of some species of the genus as well as among some allied genera grouped in the tribe Syntricheae. This is the case for the two propagulose Syntrichia amphidiacea and S. gemmascens, closely related to Streptopogon. We analyzed phylogenetic relationships between these species, based on nuclear (ITS) and two plastid (trnL-F and trnG) markers and morphological features. Species delimitation using molecular data was consistent with our preliminary morphological inference. Phylogenetic analyses were performed using maximum likelihood and Bayesian inference methods. Our results placed Syntrichia amphidiacea in the Streptopogon clade. Syntrichia gemmascens is also included in Streptopogon in spite of the discrepancy of the ITS and plastid relationships, which could be evidence of an exchange of genetic material between species in various lineages in the Pottioideae. Streptopogon is maintained as a separate genus on the basis of morphology characters, and we consider the differentiation of laminal papillae and the presence of a stem central strand as new characters in the genus. We accept Sagenotortula as distinct genus sister to Syntrichia. We consider the lack of costal dorsal epidermis and the differentiation of a crescent-shaped costal dorsal stereid band as distinctive generic characters in Syntrichia. Additionally, we include Syntrichia percarnosa as a new synonym for S. breviseta. Three names are lectotypified.

It has not been studied whether river insects and water plants are useful for an index of Zn and Fe contamination in the Kinokawa River catchment. Useful species as an index of Zn and Fe contamination needs a high concentration in a contaminated area, a low concentration in a non-contaminated area and a high and a wide range of their concentrations. Zn and Fe concentrations of crane fly larva around the closed Cu mine were high (88 to 420 and 1,300 to 9,300 mg/kg-dry for Zn and Fe). Zn and Fe concentrations of bryophyte around the closed Cu mine were high (34 to 8,900 and 110 to 58,000 mg/kg-dry for Zn and Fe). Crane fly larva (81 to 420 and 110 to 9,300 mg/kg-dry for Zn and Fe) in river insects and bryophyte (24 to 8,900 and 110 to 58,000 mg/kg-dry for Zn and Fe) in water plants had high and a wide range of Zn and Fe concentration. Therefore, it was thought that crane fly larva and bryophyte were useful species for an index of Zn and Fe contamination. Zn concentrations of Pottiaceae and Fe concentrations of Brachytheciaceae around the Cu mine area (75 to 8,900 for Pottiaceae and 940 to 58,000 mg/kg-dry for Brachytheciaceae) were high. Pottiaceae (75 to 8,900 mg/kg-dry for Zn) and Brachytheciaceae (220 to 58,000 mg/kg-dry for Fe) had high and a wide range of metal concentration. Therefore, Pottiaceae for Zn and Brachytheciaceae for Fe were useful species for an index of metal contamination. [ABSTRACT FROM AUTHOR]

The study of the diversity and distribution of bryophytes in the Benslimane region is part of a main study aiming to promote this group of organisms in Morocco. Nine stations of nearly 400 m² each were invested in the study area located south of Rabat and east of Casablanca: Rouidat Dam, Ain Dakhla, Ain Sferjla, Skhour Benslimane, Benslimane Cork Oak forest on hydromorph soil, Sakhrat Nmira, Wadi Cherrat, Beniabid forest and Wadi Sferjla. The sampling adopted is systematic according to a sinusoidal path starting from the middle of the station and covering its area; it has been spread over the four seasons of 2014, 2015 and 2018. A harvest is carried out each time a bryophyte population is encountered in the explored area. The study revealed the existence of 80 species belonging to 28 families: 4 Hornworts, 17 Liverworts, and 59 Mosses. The most represented families are Pottiaceae (11 genera and 16 species) and Brachytheciaceae (9 genera and 16 species). The species that shows the most important overlap is Targionia hypophylla and the most frequently encountered species are Targionia hypophylla and Lunularia cruciata. [ABSTRACT FROM AUTHOR]

The present part of the series provides new records of 11 taxa, among them five lichenforming fungi and six bryophytes. One lichen-forming fungus was discovered as new species in Hungary (Parmeliella triptophylla), however it was collected 115 years ago, this species should be considered as an extinct species in Hungary. One bryohyte is newly reported from Hungary (Brachy theciastrum olympicum). The occurrence of one lichen-forming fungus (Parmelia submontana) and two bryophyte species (Palustriella falcata, Ptychostomum pseudotriquetrum var. bimum) was confirmed in Hungary. Amendments to the known distribution of lichen-forming fungi species are reported from Hungary (Cladonia mitis) and Romania (Multiclavula mucida, Xanthoparmelia protomatrae) and three bryophytes from Hungary are also reported (Callicladium haldanianum, Codonoblepharon forsteri, Ephemerum cohaerens).

Cinclidotus confertus Lüth was described in 2002 from Greece and has to date only been recorded from the type locality. The taxon was supposed to differ from the widespread C. riparius (Host ex Brid.) Arn. in the red and papillose peristome teeth, as opposed to yellow and smooth peristome teeth of C. riparius. However, we found that the peristome of C. riparius was inconsistently described in the bryological literature, with some authors admitting reddish and papillose peristome teeth as well. To clarify the peristome characteristics of C. riparius and the taxonomic identity of C. confertus we studied both taxa morphologically and molecularly. Sporophyte characteristics of C. riparius are variable, but most specimens have red and papillose peristome teeth, and no other morphological difference could be found between plants assigned to C. confertus and C. riparius. The many erroneous or incomplete descriptions of the peristome characteristics of C. riparius may be related to the fact that in central Europe sporophytes are rarely produced and that the fragile peristome easily erodes. Furthermore, the phylogenetic analysis of chloroplast rps4 and nuclear ITS2 loci failed to segregate specimens assigned to C. riparius from those assigned to C. confertus, including material from the type locality and further newly discovered localities of the latter taxon. Consequently, we propose the synonymy of both taxa. [ABSTRACT FROM AUTHOR]

Anthropization has led to severe river incision in several parts of Europe. Biomonitoring is of interest to characterize this incision or, conversely, the effectiveness of ecological restoration. Mosses of the upper flood zone are good candidates for such biomonitoring as they are small organisms with limited water-intake ability. Here we studied the Dialytrichia mucronata (Brid.) Broth. – D. saxicola (Lamy) M.J. Cano species pair, both mostly encountered in the upper flood zone; the latter was hypothesized to be more resistant to water stress. We analysed 179 bryosociological relevés in the French Rhône River watershed, distributed along a wide ecological interval. We performed Pearson's Chi-square test to determine whether the latitude, altitude, substrate, and phorophyte had an effect on Dialytrichia (Schimp.) Limpr. species distribution. Assemblages between D. mucronata and D. saxicola and other moss species were tested using a multivariate procedure. Also we compiled a preliminary French departmental scale distribution map for both species. The results showed that the two species differ ecologically and might be more stenoecious than suggested by their wide synecological spectrum. Eighty-three bryophyte species were documented to be associated with the studied species of Dialytrichia. The cumulative projected inertia for the first three axes of the factorial correspondence analysis was only 23.26%, with no clear structuration. It is concluded that neither the relative occurrence of D mucronata and D. saxicola, nor the communities with these species can be used to monitor incision driven changes in vegetation.

A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M. J. Cano & J. A. Jim'enez; C. cylindrotheca (Mitt.) M. Alonso, M. J. Cano & J. A. Jim'enez; C. hyalinoblastum (Broth.) M. Alonso, M. J. Cano & J. A. Jim'enez; C. melanostomum (Mitt.) M. Alonso, M. J. Cano & J. A. Jim'enez; C. orthodontum (Mull. Hal.)M. Alonso, M. J. Cano &J. A. Jim'enez; C. sarawakense (Dixon) M. Alonso, M. J. Cano & J. A. Jim'enez; and C. stenocarpum (Th'er.)M. Alonso,M. J. Cano&J.A. Jim'enez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided. [ABSTRACT FROM AUTHOR]

Introduction. The present study investigates the taxonomy of European members of Weissia Hedw. subgenus Astomum Hampe., a group considered taxonomically difficult and including species of high conservation concern. Methods. A broad set of samples were subject to DNA sequencing and morphological analysis, plus a review of type material was undertaken. Key Results and Conclusions. Three taxonomic additions and changes are supported. (1) Weissia longifolia var. angustifolia (Baumgartner) Crundw. & Nyholm is raised to species rank, W. angustifolia (Baumgartner) D.A.Callaghan, comb. et. stat. nov. (2) The type of W. multicapsularis (Sm.) Mitt. comprises an intermix of Phascum cuspidatum Hedw. and W. longifolia Mitt., and the protologue refers to unique features of P. cuspidatum but no such features of W. longifolia. Weissia multicapsularis is therefore described as a new synonym of P. cuspidatum. (3) Plants that have been named as W. multicapsularis by modern authors comprise an undescribed species, here named W. wilsonii D.A.Callaghan, sp. nov. An illustrated key to European species of Weissia subgenus Astomum is provided. [ABSTRACT FROM AUTHOR]

Methods of macroevolutionary systematics as recently modified are explained and applied to the genus Anoectangium Schwagr. (Pottiaceae) in hyperoceanic areas of coastal northwestern North America. It was revealed that this area harbored species like those reported for the Himalayan region of northern India. Keys are provided for North American and Himalayan species of the genus. A macroevolutionary analysis, detailed in the Methods section, distinguishes and gives relationships between the species. There is strong Bayesian support for progenitor-descendant pairs and lineages. Anoectangium thomsonii Mitt. is considered a synonym of A. aestivum (Hedw.) Mitt. Anoectangium crassinervium Mitt. is transferred to Molendoa Lindb., under a nomen novum with A. handelii Schiffn. as a synonym. Anoectangium incrassatum Broth., related to the Asian A. clarum Mitt., is reported as a well-characterized species from the West Indies. Anoectangium stracheyanum Mitt. is re-lectotypified. Distinctions between A. aestivum and A. euchloron (Schwagr.) Spruce in the New World are clarified. Causal explanations in systematics are equated with entropy maximization in Shannon information analysis in the context of serial descent. A Pleistocene species pump hypothesis is advanced to explain the stenomorphic populations of species of the genus in eastern North America. [ABSTRACT FROM AUTHOR]

Introduction. Over the last years we have been engaged in studies of the South American Pottiaceae. Among the bryophyte specimens collected by us in central and northern Peru, some samples of a puzzling Pottiaceae were found. In this paper, we present our arguments for recognising these plants as a new species and its inclusion in Erythrophyllopsis Broth. Key Results. It differs most saliently from other species of Erythrophyllopsis by the combination of its oblong-ovate to ovate-lanceolate leaves, with usually fragile apex, leaf margins papillose-crenulate from apex to lower third, sometimes erose or crenate, lamina unistratose, occasionally bistratose in patches, costa broad, usually ending below the apex, without dorsal stereids near the apex where they are replaced by cells similar to those of the lamina, and short and straight peristome teeth. Conclusions. A new moss species, Erythrophyllopsis perlaticosta M.J.Cano & J.A.Jiménez, is described and illustrated from the Andean highlands in central and northern Peru. A revised identification key for the species of Erythrophyllopsis is also provided. This species grows in crevices or fissures of calcareous rocks or banks between 3050 and 4700 m. The principal distinctive characters that separate it from the nearest species of Erythrophyllopsis and related genera such as Bryoerythrophyllum P.C.Chen and Mironia R.H.Zander are discussed.

Bryophytes are the earliest plant group on Earth. They are a fundamental component of many ecosystems around the World. Some of their main roles are related to soil development, water retention, and biogeochemical cycling. Bryophytes include liverworts, hornworts, and mosses. The sequencing of chloroplast and mitochondria genomes has been useful to elucidate the taxonomy of this heterogeneous plant group. To date, despite their ecological importance only 41 mosses mitogenomes have been deposited in the GenBank. Here, the complete mitochondria genome sequence of Pseudocrossidium replicatum, a moss of the Pottiaceae family isolated in Tlaxcala, Mexico, is reported. The mitochondrial genome size of P. replicatum comprises 105,495 bp and contains the groups of genes described for other bryophytes mitogenomes. Our phylogenetic analysis shows that during the evolution of the mosses’ mitogenome, nad7, rps4, rpl16, and rpl10 genes were lost independently in several lineages. The complete mitogenome sequence reported here would be a useful tool for our comprehension of the evolutionary and population genetics of this group of plants. [ABSTRACT FROM AUTHOR]

Tortella fragilis (Drumm.) Limpr. (Pottiaceae) and Bryum nivale Müll. Hal. (Bryaceae) are recorded for the first time from the South Shetland Islands in the northern maritime Antarctic. They were discovered in the Admiralty Bay area on King George Island, the largest island of this archipelago. The two species are briefly characterized morphologically, their habitats are described, and their distribution in the Antarctic is mapped. Discovery of these species has increased the documented moss flora of King George Island to 67 species, strengthening it in the leading position among individual areas with the richest diversity of moss flora in Antarctica. Likewise, T. fragilis and B. nivale represent remarkable additions to the moss flora of the South Shetland Islands, which currently consists of 92 species and one variety, making this archipelago by far the richest bryofloristically amongst large geographic regions of the Antarctic. Comparison of recent (2018) and old (1985) photographs revealed a significant retreat of glacial cover and suggests that the collection site was likely opened for colonization only within the last several decades. The record of T. fragilis is biogeographically relevant, and constitutes an intermediate site between the species' occurrences in the Antarctic Peninsula and southern South America. The present record of B. nivale is the fourth discovery of the species worldwide, which may be helpful for the future designation of the distribution of this extremely rare species.
