Resumo A Reserva Biológica do Alto da Serra de Paranapiacaba (RBASP) foi criada em 1909 e foi a primeira área protegida na categoria de Reserva Biológica na América do Sul. Realizamos coletas em grandes áreas não coletadas com diferentes fitofisionomias e revisamos todo o material do grupo depositado no herbário de SP. Identificamos 423 espécies de briófitas com as três divisões representadas, sendo 217 espécies de hepáticas, 203 espécies de musgos e três espécies de antóceros. Lejeuneaceae foi a família com maior número de espécies, 97 spp. Dentro dos musgos, as Sematophyllaceae se destacaram com 22 espécies e os antóceros estavam representados por três espécies. Registramos 46 espécies pela primeira vez no estado de São Paulo. A Reserva possui 50 espécies endêmicas do Brasil, destas, 35 estão restritas à Mata Atlântica. As coletas de campo resultaram em 78 novos registros para a Reserva. Nosso estudo sobre briófitas é o mais extenso para a localidade em mais de um século. Os dados aqui apresentados podem, portanto, servir de base para futuras pesquisas taxonômicas e ecológicas sobre briófitas na Reserva.

Abstract The “Alto da Serra de Paranapiacaba” Biological Reserve (RBASP) was created in 1909 and was the first protected area in the category of Biological Reserve in South America. We conducted samplings in large uncollected areas, considering different phyto-physiognomies, and reviewed all the bryophyte material deposited in the SP herbarium. We identified 423 species, representing the three divisions: 217 corresponding to liverworts, 203 to mosses, and three to hornworts. The Lejeuneaceae family presented the highest richness (97 species). Within the mosses, Sematophyllaceae stood out with 22 species, and hornworts were represented by three species. We recorded 46 species for the first time in the state of São Paulo. Fifty species are endemic to Brazil, of which 35 are restricted to the Atlantic Forest. Field collections yielded 78 new records for the Reserve. Our study of bryophytes is the most extensive for the locality in over a century. Therefore, the data presented here can serve as a basis for future taxonomic and ecological research on bryophytes in the Reserve.

Abstract The Itatiaia National Park protects important Atlantic Forest remnants as well as a large number of rare bryophyte species. We reassessed the conservation status of 45 species of endemic and/or threatened mosses occurring in high-altitude fields in the Park. The conservation analysis followed the International Union for Conservation of Nature guidelines. The GeoCAT software was used to calculate the Extent of Occurrence (EOO) and Area of Occupancy (AOO). The threat vectors were characterized based on field observations and data from the literature. After the reassessment, 31 species were considered threatened, with 16 being considered vulnerable (VU), seven critically endangered (CR), and eight endangered (EN). Two species were considered “near threatened” (NT) and three were considered “data deficient” (DD), and seven were considered “least concern” (LC). The main threats in that region are wildfires and excessive tourism - factors that lower habitat quality and reduce their EOO and AOO. Recommendations to minimize imminent losses of the local bryoflora include incentives for research and microhabitat protection. Our results are designed to aid in the elaboration of conservation strategies for mosses in the Serra da Mantiqueira mountains. 4 andor or highaltitude high altitude guidelines (EOO AOO .

Abstract Epixylic bryophytes - colonizers of decaying logs - are the third most endangered group of these plants, but few studies have been focused on them. Thirty logs in the proximity of three trails in a nebular forest in the Serra da Bocaina National Park in the state of São Paulo, Brazil, were sampled. Our objective was to study and compare the composition of the communities in three levels of decomposition (10 plots per level): X = initial (solid wood and intact cortex); Y = intermediate (partially soft wood with cracks) and Z = advanced (completely soft wood with undefined shape). To compare the floristic relationships among plots, we used Sørensen’s similarity coefficient and phytosociological parameters. We found 74 species of bryophytes (40 genera and 24 families), 80% of which were pleurocarpous mosses. The results showed no preference of the species for any level of decomposition and no spatial structure (similarity x distance). We conclude that epixylic bryophyte species in Atlantic Forest are generalists and colonize different types of environments and substrates. plants them Paulo Brazil sampled 10 (1 level) solid cortex cortex) partially cracks completely shape. shape . shape) Sørensens Sørensen s parameters 7 40 (4 2 families, families , families) 80 mosses distance. distance distance) substrates 1 ( 4 8

ABSTRACT The Herbarium VIES is one of the five botanical collections housed in Espírito Santo State and includes the second largest number of samples. The Bryophytes group was not studied for many years and had about only 120 exsiccates until 2019, however, the collection was reorganized, new studies are being carried out and currently almost 3,000 samples are deposited. And now it is the biggest bryophyte collection of the state. During this process, 242 specimens were identified and reported in this work, with 121 species, in addition to new records for the state. Therefore, this work expands the knowledge on the bryophyte’s diversity in Espírito Santo State and partially fills the gap in studies for this group in the state. 12 2019 however reorganized 3000 3 000 3,00 deposited state process 24 species Therefore bryophytes s 1 201 300 00 3,0 2 20 30 0 3,

Synopsis of the genus Brachymenium Schwägr. (Bryaceae) in Brazil). Bryaceae is a moss family with ten genera and 660 species worldwide. There are 54 species in four genera in Brazil. Brachymenium is the second largest genus and is characterized by the corticolous habit, erect capsules and rudimentar endostome. A revision of the genus is necessary due to the difficulty in identifying the taxa and to the poorly sampled Brazilian plants in literature. The aim of this work was to perform a taxonomic treatment of Brachymenium in Brazil, comprising diagnostic descriptions and illustrations, comments, maps and a key. Were analyzed 300 exsiccatae of Brachymenium from national and international herbaria and were recognized nine species. Five taxa were excluded from Brazil. Four species are endemic of Brazil: Brachymenium elimbatum, B. hornschuchianum, B. regnellii and B. sublinearis; another four are Neotropical: B. consimile, B. klotzschii, B. morasicum and B. radiculosum, and only one is Pantropical: B. acuminatum.

Brachymenium é o segundo maior gênero e é caracterizado por apresentar hábito corticícola, cápsulas eretas e endóstoma com membrana basal alta e porção distal rudimentar. Há a necessidade de revisão do gênero em virtude da dificuldade de identificação dos táxons e da sub-amostragem de plantas brasileiras na literatura. O objetivo deste trabalho foi apresentar um tratamento taxonômico do gênero para o Brasil, contendo descrições e ilustrações diagnósticas, comentários, mapas e chave. Foram analisadas 300 exsicatas de Brachymenium de herbários brasileiros e internacionais e reconhecidas nove espécies. Foram excluídos cinco táxons do Brasil. Quatro espécies são endêmicas do Brasil: B. elimbatum, B. hornschuchianum, B. regnellii e B. sublinearis; quatro são Neotropicais: B. consimile, B. klotzschii, B. morasicum e B. radiculosum; B. acuminatum é Pantropical.

The campus of the Universidade Federal de São Carlos, in the municipality of Sorocaba, is composed of a forest remnant characterized by vegetation of seasonal semidecidual tropical forest and cerrado. We recorded 96 species of bryophytes in the area: 56 mosses (Fissidentaceae is the richest, with 11 spp.) and 40 liverworts (Lejeuneaceae is the most representative, with 21 spp.). Eight species are endemic to Brazil and two were mentioned for the first time in the State of São Paulo (Fissidens allionii Broth. and Lejeunea subsessilis Spruce). The predominance of corticolous species and mat life form indicate a strong relationship with the microclimate conditions of the environment, as well as the availability of substrate. The simultaneous presence of species from the Atlantic Forest and the Cerrado indicates an transition zone bryoflora, at the same time that subcosmopolitan and ruderal species with wide distribution express the secondary character of the forest remnant.

ABSTRACT Andreaea subulata is a moss species that occurs throughout the Southern Hemisphere. In Brazil, it is restricted to high-altitude fields in the state of Rio de Janeiro. The last recorded collection of this species in the country was made 95 years ago in the Itatiaia National Park (INP). It was never seen or collected again since then and it was, therefore, considered ‘probably extinct’ in Brazil. Here we report the rediscovery of this species in the INP and provide information on its ecology and conservation status in Brazil (Critically Endangered) as well as conservation recommendations. The newly found population is very small and grows on granitic rocks in humid areas. The principal threat to the species in Brazil is habitat loss.

ABSTRACT Bryaceae is a species-rich moss family comprising ten genera and 660 species, with four genera and 54 species occurring in Brazil. Bryum is the largest genus, with 440 cosmopolitan species, while Anomobryum comprises 47 cosmopolitan species. Identifying taxa in Bryaceae is usually a difficult task, mainly due to the lack of the sporophyte in herborized specimens. This study aimed to provide a taxonomic treatment for the species of Anomobryum and Bryum in Brazil. Field expeditions were performed in all Brazilian biomes and States, with specimens deposited in the SP herbarium. We examined type specimens and collections from national and international herbaria, but mostly from the SP herbarium. Two species of Anomobryum and 18 species of Bryum were recorded for Brazil. Twenty species occur in the Atlantic Forest, with Bryum pallescens, Anomobryum conicum and A. julaceum being exclusives. Bryum pallescens is a new record for Brazil, and B. riparioides is a reestablished name also endemic to Brazil. We present the first description of the sexuality of Bryum renauldii. Ten taxa of doubtful occurrence and 20 excluded names for Bryum were reported for Brazil.

ABSTRACT Rio Turvo State Park (RTSP) is a Conservation Unit located within the Atlantic Forest biome in the Vale do Ribeira region of the State of São Paulo, Brazil. Considering the lack of knowledge regarding its bryoflora, we performed a floristic inventory of RTSP (following the random-walk method), the results of which we report here including discussion of the geographical distribution (Brazil and worldwide), substrate colonization, life forms and reproduction of the species. We found a total of 414 species, which represents 30 % of all known bryophyte species in Brazil. Dioicous species were predominant over monoicous species, the most colonized substrate was tree trunk (40 % of all species) and the predominant life form was mat (47 %), indicating that the floristic composition is influenced by the environmental conditions of the area (high humidity, dense vegetation and shading). Although anthropogenic intervention is present in RTSP, it harbors huge biodiverse potential, since 22 % of the species are rare. Furthermore, 16 new occurrences were recorded for the State of São Paulo. The information provided by this study exalts the importance of this Conservation Unit in the preservation of bryophytes, as well as all the biodiversity of its included ecosystems.

Bryophyta, the mosses, are an abundant plant group in humid environments. In the Atlantic Coastal Forest of Southeastern Brazil, they are found in great richness and diversity, especially in the montane regions.  In this context, the Parque Nacional do Caparaó, where our study was conducted, is known for its mountain environment and high altitude. Although a considerable number of moss collections from the western part of the park is already deposited in herbaria, the eastern side belonging to the state of Espírito Santo State had been undersampled until now. For this pioneering work, we covered the park's main visitation trails during three intensive days of collections. We found 59 species of mosses, belonging to 38 genera and 22 families. Nine species are new occurrences for the state and 14 are Brazilian endemics. Most species were found growing on soil. We found more species at altitudes above 1,500 m a.s.l. Sematophyllaceae was the richest moss family.

No Brasil, os musgos (Bryophyta) são encontrados com maior riqueza e diversidade na Mata Atlântica, especialmente em ambientes montanhosos e úmidos como o encontrado no Parque Nacional do Caparaó.  A coleta do material foi realizada durante três dias onde percorremos as principais trilhas de visitação do parque. Foram identificadas 59 espécies pertencentes a 38 gêneros e 22 famílias. Nove espécies são novas ocorrências para o Estado e 14 são endêmicas do país. A família mais rica em espécies foi Sematophyllaceae. As espécies terrícolas são as mais frequentes. A maior riqueza de espécies foi observada em altitudes acima de 1.500 m alt. Embora se tenha considerável número de coletas depositadas nos herbários, oriundos da porção oeste do parque, este é um trabalho pioneiro na região que se estende pelo Espírito Santo.
