To test infrageneric classification and species delimitation within the pantropical moss genus Taxithelium (Pylaisiadelphaceae), we constructed a molecular phylogeny using three chloroplast loci (fnîL, psfcT and rpsi), three mitochondrial loci (rps3, yxadS and nadi-5) and the nuclear marker hoi. Analyses of each locus separately and in various combinations, all support the monophyly of Taxithetium. Two major clades corresponding to taxonomically recognized subgenera were resolved within the genus. The first clade is composed of at least five smaller groups, four of which only include Southeast Asian plants and one is from the Americas and Africa; the latter is nested within the Southeast Asian groups. The second group appears to have a Southeast Asian origin with two dispersal events into America. Taxithelium is highly variable morphologically and includes plants with pluripapillose leaf cells as well as plants that lack papillae. Our data show that species T. nepalettse, T. leptosigmatum, T. conccivum, T. instrnhini, T. lindbergii and T. isocladum are each demonstrably monophyletic. On the other hand, T. plamim and T. kerianum as circumscribed today are polyphyletic. The hol nuclear locus is used for the first time, with promising results for moss phylogenetic investigation.

“…The addition of new records to the list of bryophytes in Brazil increased the knowledge of the diversity in this group, and emphasized the importance of new records or new taxa published by Costa et al (2008), Ilkiu-Borges & Pereira Alvarenga (2008, IlkiuBorges & Gradstein (2008), Bastos (2011), Bordin et al (2011), Câmara & Carvalho-Silva (2011), Peralta (2011), Ilkiu-Borges (2011), Câmara & Carvalho-Silva (2012, Brito & Ilkiu-Borges (2012a,b), Peralta & Boas-Bastos (2012), Peralta & Reiner-Drewald (2013), and Ayub et al (2014).…”

The bryoflora of Brazil comprises 1,524 species, 117 families, and 413 genera (11 hornworts, 633 liverworts, and 880 mosses). The most diverse families of liverworts are: Lejeuneaceae (285 species), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae and Metzgeriaceae (26 each), Lophocoleaceae (18), Aneuraceae (15), and Calypogeiaceae (13); while, for the mosses, we have: Sphagnaceae (83 species), Fissidentaceae (65) Pottiaceae (63), Dicranaceae (54), Bryaceae and Sematophyllaceae (53 each), Orthotrichaceae and Pilotrichaceae (51 each), Calymperaceae (48), and Hypnaceae (28). These large groups account for 71% of the Brazilian bryophyte species. Lejeuneaceae and Sphagnaceae are the families with highest number of endemic taxa (54 and 60 species). The Atlantic Rainforest presents the greatest number of species (1,337), followed by the Amazon Rainforest (570) and Cerrado (478). The highest number of endemic species (242) is associated with the Atlantic Rainforest, where the Dense Ombrophilous Forest concentrates 73% of the species with 62% endemism. The Southeastern region is the most diverse in number of species (1,228) and with more endemism (219). Most endangered species are restricted to the Atlantic Rainforest of southeastern Brazil, which is the diversity and endemism centre for mosses and liverworts. The information currently presented by the Brazilian List is close to the real bryophyte diversity found in the country. Key words: hornworts, liverworts, mosses, bryoflora, South America. ResumoA brioflora do Brasil conta com 1.524 espécies, 117 famílias e 413 gêneros (11 antóceros, 633 hepáticas e 880 musgos). As famílias mais diversas de hepáticas são: Lejeuneaceae (285 espécies), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae e Metzgeriaceae (26 cada), Lophocoleaceae (18), Aneuraceae (15) e Calypogeiaceae (13); e de musgos são: Sphagnaceae (83), Fissidentaceae (65), Pottiaceae (63), Dicranaceae (54), Bryaceae e Sematophyllaceae (53 cada), Orthotrichaceae e Pilotrichaceae (51 cada), Calymperaceae (48) e Hypnaceae (28), totalizando 71% das espécies de briófitas do país. Lejeuneaceae e Sphagnaceae são as famílias com maior número de endemismo (54 e 60 espécies). A Mata Atlântica apresenta o maior número de espécies (1.337), seguida pela Amazônia (570) e pelo Cerrado (478). Também apresenta o maior número de espécies endêmicas (242), com a Floresta Ombrófila Densa concentrando 73% dos táxons e 62% dos endemismos. A Região Sudeste é a mais diversa (1.228) e com maior endemismo (219). A maioria das espécies ameaçadas de extinção está restrita a Mata Atlântica do sudeste, que é um centro de diversidade e endemismo para musgos e hepáticas no país. As informações da Lista de Espécies da Flora do Brasil estão próximas da real diversidade de briófitas do país. Palavras-chave: antóceros, hepáticas, musgos, brioflora, América do Sul.

“…When examining the distribution of acro and pleurocarpous mosses in the Atlantic Forest, the data show a balance, with three studies (Oliveira et al 2002;Costa & Silva 2003;Siqueira et al 2011) showing the occurrence of more acrocarpous than pleurocarpous mosses, and three studies (Visnadi 2005;Santos & Costa 2008;Valente et al 2009) showing the opposite. Note that we used only those studies in which there was a complete list of mosses and families, and those wrongly applied in a category were corrected using the criteria proposed by La Farge-England (1996) and Goffinet et al (2009).…”

In the other works consulted (Costa & Silva 2003;Visnadi 2005;Santos & Costa 2008;Valente et al 2009), it was not possible to ascertain the most collected species.…”

Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas, " at 19°16'00" S and 43°32'49" W and an altitude of 1,188 m. The objective of this study was to survey the Division Bryophyta in a gallery forest within the National Park of Serra do Cipo, Minas Gerais. Collections were made during the months of November 2009 and July 2011. We found 15 families, 26 genera, 43 species, and 4 varieties of mosses. The families with the largest number of species were Leucobryaceae (10), Sematophyllaceae (9), and Calymperaceae (6). Other families included Fissidentaceae (3), Bryaceae, Pylaisiadelphaceae, Pottiaceae, and Orthotrichaceae (2 spp. each); Brachytheciaceae, Cryphaeaceae, Fabroniaceae, Helicophyllaceae, Hypnaceae, Polytrichaceae, and Sphagnaceae had only 1 sp. each. Three new records for the state of Minas Gerais were found: Acroporium caespitosum, A. longirostre, and Colobodontium vulpinum.
