AbstractThe new species Byssoloma catillariosporum and Porina isidioambigua are described from NE Brazil. The first is reminiscent of B. leucoblepharum but differs by the consistently uniseptate ascospores. The second is characterized by tiny isidia and black perithecia with relatively large, 3-septate ascospores. Both species were found at the Área de Proteço Ambiental (APA) Morro do Urubu, an area of c. 214 hectares in the large (500 000 inhabitants) city of Aracaju. It is the only urban Mata Atlântica remnant in Aracaju, with mesophytic deciduous and semi-deciduous forest, and cerrado enclaves in isolated points.

AbstractThe new species Micarea corallothallina is described from Serra da Jibóia, Bahia, NE Brazil. It has a gnarled, coralloid, isidiose thallus and pale botryose apothecia. It was found in the Serra da Jibóia, a mountainous range with a maximum elevation of 800 m on smooth bark of trees. This Mata Atlantica fragment is located in the Santa Terezinha municipality, Bahia, NE Brazil, near the Castro Alves municipality boundary. This area can be considered as a rainforest enclave surrounded by Caatinga, and belongs to a disjunct set of mountains that extend from the southern coast of the state to the North-west and North.

AbstractTwo new species, Malmidea pallidoatlantica and Malmidea sulphureosorediata, are described from NE Brazil. The first is close to M. atlantica but differs by the hyaline or pale hypothecium. The second species is a bright golden yellow sorediate crust which is assigned to the genus Malmidea because it contains the same anthraquinone pigment as M. atlantica and M. pallidoatlantica. The three species together could be referred to as the Malmidea atlantica group. Both new species were found in Mata Atlântica fragments. Malmidea sulphureosorediata was found in the Serra da Jibóia, a mountain range with a maximum elevation of 800 m, in a transitional area between the Atlantic forest and Caatinga vegetation in Bahia State. Malmidea pallidoatlantica was found in Mata do Crasto, one of the most important Atlantic forest remnants in Sergipe. It is a well-preserved Mata Atlântica relict of c. 700 hectares, at sea level.

A fragmentação e destruição da Mata Atlântica tornam a sua conservação fundamental. A serapilheira é um importante componente desse sistema e apresenta diferenças na deposição nos diferentes ecossistemas brasileiros. Com isso, o objetivo deste estudo foi avaliar o efeito da precipitação e da temperatura do ar no aporte de serapilheira em fragmentos florestais localizados em Sorocaba, SP. A quantidade média de serapilheira aportada foi de 6,9 ± 0,4 mg.ha-1.ano-1, formada por 65% de folhas. Houve diferenças entre as deposições nas estações do ano, sendo que a menor quantidade foi depositada no período seco. A correlação da serapilheira e suas frações não foram significativas quando analisada para o mesmo mês da avaliação da temperatura do ar e precipitação. Porém, quando se relacionam meses anteriores, a correlação é mais expressiva, demonstrando que a resposta da vegetação a variações ambientais não é imediata.Palavras-chave: Clima; sazonalidade; Mata Atlântica. AbstractInfluence of precipitation and air temperature in production of litterfall in stretch of seasonal forest. Fragmentation and destruction of the Atlantic Rainforest make its conservation essential. The litter is an important component of this system, and reveals differences in deposition in the different Brazilian ecosystems. This research aims to evaluate the effect of rainfall and air temperature on litterfall input in a forest fragment at the municipality of Sorocaba, São Paulo State, Brazil. The average contribution of litterfall was 6.9±0.4Mg ha-1 yr-1, comprising 65% of leaves. There were differences between the seasons, with the less amount in the dry season. The correlation of litter and its fractions was not relevant for the same month of air temperature and rainfall measurement. However, the correlation is significant when related to the previous month, demonstrating that the response of vegetation to environmental changes is not immediate.Keywords: Climate; seasonality; Atlantic forest.

Resumo: A Mata Atlântica é o terceiro maior bioma brasileiro e possui uma dasmaiores biodiversidades do mundo. Tem função reguladora do fluxo dos mananciaishídricos, mantém a fertilidade do solo, controla o equilíbrio climático, eevita deslizamentos de escarpas e encostas de regiões serranas. Desde temposcoloniais vem sofrendo os impactos da atividade exploratória e do crescimentopopulacional e urbano, que causaram fragmentação de ecossistemas, perda debiodiversidade e deterioração de recursos naturais. Aproximadamente 8,5% desua cobertura são áreas preservadas com mais de 100 hectares. A conservaçãodesses fragmentos e a recuperação de áreas degradadas são fundamentais paraa manutenção do bioma e da qualidade de vida das populações associadas a ele.Palavras-chave: Bioma Mata Atlântica.

Since colonial times it has been suffering the impacts of exploitation,population growth and urban expansion, which caused ecosystem fragmentation,biodiversity loss, and deterioration of natural resources.

The objective of this work was to determine how taxonomy benefited from the ecological quantitative and site-based sampling methods in enchytraeids studies. Enchytraeids (small relatives of earthworms) were sampled in different phases of rain forest regeneration in the southern Mata Atlântica in Paraná, Brazil. The research combined ecological and taxonomic work, because enchytraeids are poorly studied and difficult to identify, and many new species were expected. The provision of large numbers of specimens enabled the test of species diagnoses by investigating the ranges of character variations in a larger series of specimens. Simplified species diagnoses adapted to the local conditions that allowed the identification of all specimens, juveniles included, were developed. Key characters and character states are presented for the three genera: Achaeta, Hemienchytraeus and Guaranidrilus. Among several new species, a rare species, possibly a remnant of the autochthonous forest fauna, was found and described.

A New Species

Chresta filicifolia is described and illustrated. It is a perennial herb known only from open vegetation on top of small rock outcrops at the Rio Doce Valley in Eastern Minas Gerais, Southeastern Brazil. This is the first record of a species of Chresta endemic to a phytogeographic domain other than the Cerrado and Caatinga, since those outcrops are included in the Mata Atlântica Domain (Atlantic Forest). The new species is closely related to C. harleyi and C. hatschbachii, but differs from these by its leaves, which are larger and more deeply lobed than those of the other two species, and also by its florets and cypselae, which are both larger in Chresta filicifolia. Moreover, the two other species are allopatric from C. filicifolia, being restricted to the Caatinga Domain. The southernmost distribution of C. harleyi lies more than 500 km away from the locality where the new species is found, making this discovery unexpected, and raising interesting biogeographical questions, which are briefly addressed here.
