“…Cribraria violacea also produce small sporangia, and is very common on the cortex of living trees and, less frequently, on dead wood. In Brazil, this species has been recorded from almost all northeastern states, plus once in the South Region (Santa Catarina) and once in the Southeast Region (São Paulo), occurring as corticolous and lignicolous in the Atlantic Forest and Caatinga (Gusmão et al 2005;Silva & Cavalcanti 2010;Bezerra et al 2011;Silva & Cavalcanti 2012). Echinostelium minutum is known only from the Northeast (Alagoas, Bahia, Maranhão, Pernambuco) and…”

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 km 2 , it encompasses part of the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte in northeastern Brazil. Here we present an identifi cation key to 73 species of Myxomycetes that compose the known corticolous myxobiota of the Dense Ombrofi lous Lowland Forest, Semideciduous Lowland Forest, Restinga Forest and Mangrove environments of CEPE. Specimens included here were found developed in natural conditions in the fi eld or obtained through moist chamber culture. Among the species found, Arcyria cinerea, Clastoderma debaryanum, Cribraria confusa, C. violacea and Echinostelium minutum were the most common; and Comatricha longipila, Licea pedicellata, Paradiachaeopsis longipes, Perichaena calongei and Stemonaria fuscoides were the most rare. Our data indicates that the species richness of corticolous myxomycetes in rainforests is lower than that of temperate forests. Th ese same data also suggest that taxonomic diversity (mean number of species per genus) is similar to, or higher than, that found in temperate regions of the world.

“…Litter in natural environments and agricultural areas are good microhabitats for myxomycetes, as evidenced by Bezerra et al (2011) who, in field collections and cultivation in a moist chamber, recorded 15 species in the litter and aerial litter of Cecropia adenopus Mart. ex Miq., in a fragment of Atlantic Forest, in Rio Grande do Norte, a northeast Brazilian state; Physarales (47%) and Trichiales (33%) were predominat, with most species represented by a single specimen.…”

A nogueira-pecan (Carya illinoinensis, Juglandaceae) foi introduzida no Brasil no início do século XX por imigrantes americanos e seu cultivo atualmente se estende desde o Rio Grande do Sul até Minas Gerais, com aproximadamente 2,4 mil hectares plantados. Apresenta-se o primeiro relato de mixomicetos associados à serapilheira de C. illinoinensis, diretamente observados no campo, esporulados sobre folhas secas (Physarum cinereum, P. melleum, P. polycephalum), gravetos e folhas secas (Diachea leucopodia) e galhos (Fuligo cinerea, F. septica, Hemitrichia serpula var. serpula). As espécies mais constantes foram P. melleum e D. leucopodia. Fuligo cinerea é registrado pela primeira vez para o Rio Grande do Sul; D. leucopodia e P. cinereum são citados pela primeira vez para a porção brasileira do Pampa, elevando para 61 o número de espécies conhecidas para o bioma.

The Brazilian Atlantic Rainforest is considered one of the world biodiversity hotspots, with high levels of endemism. Studies on the myxobiota of Atlantic Rainforest have been carried out mainly in the Northeast region of Brazil but the ground litter microhabitat has only been included in a few of these studies. This study aimed to record the composition and diversity of the myxobiota of the ground litter of Pedra Talhada Biological Reserve and to expanding the knowledge about the microbiota of Atlantic Rainforest. Samples of ground litter were collected at the end of the dry season and the beginning of the rainy season and 1,080 moist chambers were mounted. The identification of the specimens obtained were based on a morphological examination. Were obtained 86 specimens, identified, and registered in the UFP herbarium. Plasmodia and/ or sporocarps were recorded in 23.7% of the moist chambers. The inventory resulted in 13 new records for Alagoas raising the number of known species in the state to 61. Perichaena longipes and Stemonitopsis gracilis are registered for the first time in Northeast Brazil and in the Atlantic Rainforest, Macbrideola spinosispora is the first record for Brazil and Licea sp. is likely a new taxon. A key to identify the species occurring in Alagoas is presented, as well as, distribution and comments of the species in Brazil.
