Bryophyte Diversity and Evolution <p><strong>Bryophyte Diversity and Evolution </strong>is an international research journal of the <a href="" target="_blank" rel="noopener">International Association of Bryologists</a> (IAB). BDE publishes review articles and original contributions on the diversity and biology of bryophytes (i.e., liverworts, mosses and hornworts), including bryophyte chemistry, conservation, ecology, genetics, genomics, ontogeny, mutualism, phylogeography, physiology, and systematics. All contributions are peer-reviewed. It was previously published under the title Tropical Bryology (1989–2013).</p> Magnolia Press en-US Bryophyte Diversity and Evolution 2381-9677 <p><strong><em>Schistidium foraminis-martini</em> <em>sp. nov.</em> (Grimmiaceae), a high mountain calcicole from the European Alps molecularly related to <em>S. agassizii</em></strong></p> <p><em>Schistidium foraminis-martini</em> is described as a new species from the Austrian and Swiss Alps. The taxon is characterized by a warm brown coloration, ovate, concave and muticous leaves with rounded apices, ellipsoid capsules, constricted at mouth, the presence of stomata and a reduced, truncate peristome. Based on sequences of the ITS region the new species is phylogenetically rather isolated, exhibiting the closest relationship to <em>S. agassizii</em> which shares the muticous leaves but differs in having narrowly lingulate-lanceolate, almost flat leaves, cyathiform capsules and a perfect peristome. <em>Schistidium foraminis-martini </em>grows on moist calcareous rocks in the alpine and nival belt.</p> THOMAS KIEBACHER HERIBERT KÖCKINGER HANS H.

Herein, we continue by further describing and illustrating two new species, as well as by providing evidence for substantial geographical extensions of another five taxa. Two new species, <em>Ceratolejeunea ocirii </em>and<em> Ceratolejeunea semicornua </em>are herein described. <em>Cololejeunea appressa</em> is newly recorded for Brazil, and <em>Cheilolejeunea savannae</em>, <em>Cololejeunea clavatopapillata</em>, <em>Prionolejeunea galliotii</em> and <em>Plagiochila eggersii</em> are new records for the state of Amazonas, Brazil.</p> ADRIEL M.

During the assessment of moss diversity in various localities of Manipur a total 126 species of mosses belonging to 84 genera in 34 families have been investigated and enumerated. Ten species, namely <em>Amblystegium</em>&nbsp;<em>serpens,Entodontopsis leucostega</em>, <em>Entodontopsis tavoyensis</em>, <em>Homalia trichomanoides</em>, <em>Lindbergia duthiei, Philonotis mollis</em>, <em>Philonotis thwaitesii</em>, <em>Taxiphyllum giraldii,Tortella humilis</em> and <em>Thuidium sparsifolium</em> are new additions to Eastern Himalaya, while 92 species of mosses have been reported for the first time from Manipur. Ten Indian endemic taxa have also been identified from the explored sites. The majority of the taxa were recorded from epiphytic habitats.</p> ASHISH KUMAR ASTHANA VINAY SAHU VISHAL AWASTHI Copyright (c) 2021 2021-12-23 2021-12-23 44 1 22–47 22–47 10.11646/bde.44.1.3 <p><strong>Phylogenetic study of the genus <em>Pohlia</em> (Mielichhoferiaceae, Bryophyta) based on chloroplast DNA sequences</strong></p> <p>The phylogenetic circumscription and taxonomic status of the genus <em>Pohlia</em> in the Mniaceae <em>sensu lato</em> was investigated based on chloroplast DNA sequences (<em>rbc</em>L, <em>rps</em>4, and <em>trn</em>L-F), with a focus on species occurring in Japan. The maximum likelihood and Bayesian inference analyses of sequences obtained from 34 species of Mniaceae <em>s.l.</em>, including 13 <em>Pohlia</em> species, suggested that the genus <em>Pohlia</em> and the family Mielichhoferiaceae are not monophyletic in their present circumscription, but confirmed that the family Mniaceae is monophyletic in its traditional sense. These results are congruent with previous molecular phylogenetic studies. Three distinct clades were recognized in the Mielichhoferiaceae, almost corresponding to three sections of <em>Pohlia</em> (<em>Pohlia</em>, <em>Cacodon</em> and <em>Apalodictyon</em>). One of them branched off first within the Mniaceae <em>s.l.</em>, and the other two were sister to the remainder of the Mniaceae <em>s.l. </em>The single included<em> Schizymenium</em> formed a monophyletic group with <em>Pohlia </em>sect. <em>Pohlia</em> and <em>Epipterygium</em> with <em>Pohlia</em> sect. <em>Apalodictyon</em>, confirming the results of previous studies. The results indicate that the taxonomic status of the genus <em>Pohlia</em> and family Mielichhoferiaceae are in need of revision. Phylogenetic analyses nested the accessions of <em>P. camptotrachela</em> within <em>P. annotina</em> and <em>P. flexuosa</em> clades, highlighting the need for taxonomic revision of Japanese propaguliferous <em>Pohlia</em> species.</p> TAKAYUKI OHGUE HIROYUKI AKIYAMA HIROSHI SUZUKI-AZUMA HIDETOSHI NAGAMASU Copyright (c) 2021 2021-12-23 2021-12-23 44 1 48–60 48–60 10.11646/bde.44.1.4
