| First records of myxomycetes in the North region of Brazil go back to the 19th century. Nevertheless, the myxobiota of this region is still largely unexplored, with only 42 species recorded, distributed in 20 genera and seven families. The objectives of this paper were to characterize the Myxomycetes collection of the Herbarium of the Federal University of Roraima (UFRR) and to add new records for the myxobiota of this State. The collection holds specimens collected in fragments of Open Ombrophilous Forest, Seasonal Semi-deciduous Forest, Riparian Forest, deforested areas and urban home gardens in the state of Roraima. The 157 exsiccates were analyzed and identified or redetermined based on identification keys, descriptions and illustrations. The... |

| The present study was carried out on three trails, each presenting a different degree of disturbance, within the Pau-Ferro Forest Environmentally Protected Area, a 600 ha area of highland forest located in the municipality of Areia (06°58'12"S; 35°42'15"W; elevation, 400-600 m), in the state of Paraíba, Brazil. In 2005, we analyzed the species richness, abundance, constancy and phenology of myxomycetes over seven consecutive months (rainy and dry seasons) in five types of microhabitats: dead tree trunks, the bark of living trees, basidiomata, ground litter and aerial litter. A total of 753 specimens of 48 species were obtained from the trails known as Flores (4 km), Boa Vista (3 km) and Cumbe (700 m). The Sørensen similarity coefficient revealed that the... |

| The known distribution of Perichaena calongei, P. chrysosperma, P. corticalis, P. depressa, P. microspora, P. pedata and P. vermicularis in the nine states that comprise Brazil's Northeast Region (1,548,672 km2) is presented herein, enhancing our understanding of the distribution of the genusPerichaena (Trichiaceae, Myxomycetes) in the Neotropics. This inventory encompasses a 100-year period (1914-2014), and analyzes material deposited in herbaria and collected by the authors. The collected material came from areas of thorny deciduous vegetation typical of the Caatinga biome and portions of savannah in the continent's interior, rainforests,restingas (tropical moist broadleaf forests found along Brazil's coastal spits) and mangroves of the Atlantic Forest... |

| ABSTRACT Situated within the Atlantic Forest domain, the Centro de Endemismo Pernambuco (Pernambuco Center of Endemism) - CEPE is regarded as a priority for biodiversity conservation worldwide. Covering an area of approximately 56,000 km2, it encompasses part of the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte in northeastern Brazil. Here we present an identification key to 73 species of Myxomycetes that compose the known corticolous myxobiota of the Dense Ombrofilous Lowland Forest, Semideciduous Lowland Forest, Restinga Forest and Mangrove environments of CEPE. Specimens included here were found developed in natural conditions in the field or obtained through moist chamber culture. Among the species found, Arcyria cinerea, Clastoderma... |

| Visando contribuir com informações sobre a diversidade de Myxomycetes em florestas úmidas e savanas Neotropicais, foram inventariadas as espécies de Physarales associadas a diferentes microhabitats no Parque Nacional Serra de Itabaiana, Sergipe, Brasil (10º40'52"S e 37º25'15"W, 180-670 m, 7966 ha). Durante 20 meses consecutivos foram efetuadas coletas de esporocarpos e de amostras de vários tipos de substratos a serem utilizados na preparação de 590 câmaras-úmidas. Coleções representativas do material estudado foram depositadas no Herbário UFP, com duplicatas no herbário MA - Fungi. A abundância e a constância de cada espécie foram determinadas. Apresenta-se uma lista comentada das sete espécies de Didymiaceae e 24 espécies de Physaraceae identificadas e... |

| Order Ceratiomyxales, which belongs to subclass Ceratiomyxomycetidae, includes the exospore bearing Myxomycetes, solely comprising family Ceratiomyxaceae and genus Ceratiomyxa, with four species. Based on the literature, on herbarium collections, and on recent surveys carried out by the authors in different states and ecosystems, it was possible to determine the occurrence and distribution of C. fruticulosa (cosmopolitan),C. morchella and C. sphaerosperma (predominantly tropical or subtropical) in northeastern Brazil. Species descriptions and illustrations are presented, as well as a map of their geographical distribution in eight of the nine states of Northeast Brazil. This order is being recorded for the first time for the state of Sergipe. Ceratiomyxa... |
