The Amazon has a high diversity of fungi, including species of the genus Daldinia (Ascomycota, Xylariaceae), which produce secondary metabolites with recognized nematicidal and antimicrobial activity. The ecological role of Daldinia is important, as stromata serve as refuges to many insects and arthropodes, and the fungi contribute to the degradation of vegetable organic matter. The aim of this study was to analyze the taxonomic features and mycelial growth conditions in vitro of a Daldinia specimen collected in the Brazilian Amazon. Morphological and molecular studies of the fungus identified it as D. eschscholtzii. To evaluate mycelial growth, we cultivated the fungus at 20, 25, 30, 35, and 40 °C in malt extract-peptone agar (MEPA), malt extract-peptone... |

In this study, we identified six polyporoid species of Agaricomycetes: Abundisporus roseoalbus, Fuscocerrena portoricensis, Oligoporus caesius, Antrodiella duracina, Inocutis jamaicensis and Inonotus venezuelicus. All of these represent new records for the state of Santa Catarina, located in southern Brazil. For Brazil as a whole, this is the second record of O. caesius. |

From March/1993 to March/1995, airborne fungi were isolated from the "Vale do Rio Moji" (highly affected by the air pollution caused by fertilizer industries, steel works, cement factories and chemical products industries, among others) and from the "Vale do Rio Pilões" (less affected by the air pollution), both in the municipality of Cubatão, São Paulo State, Brazil, by exposing Petri dishes with potato dextrose agar medium, placed one meter from the ground, during 5 min. After 5 days of incubation at 20ºC, the colonies of the fungi were purified and identified, resulting in the identification of 39 taxa, three unidentified strains of Fusarium and non-sporulating cultures. A total of 28 taxa, one unidentified strain of Fusarium and non-sporulating fungi... |

ABSTRACT Syngonanthus elegans is an endangered plant species occurring in the Brazilian Cerrado whose interaction with arbuscular mycorrhizal fungi (AMF) is poorly understood. The aim of this work was to evaluate the occurrence of AMF species and mycorrhizal colonization of S. elegans in two sampling areas named "Soberbo" stream (Soberbo) and "Parque Nacional das Sempre-Vivas" (Park), both found in Diamantina-MG, Brazil. In each area, one plot (100 x 100 m) was established, and roots and soil samples near the roots were collected from 10 plants in each plot. Further sampling included three specimens each of Loudetiopsis chrysothrix and Xyris sp.. Typical mycorrhizal colonization structures were observed in S. elegans roots, and colonization was measured at... |

In the State Park Parque Estadual das Fontes do Ipiranga - PEFI, located in the city of São Paulo, samples of submerged mixed leaf litter were collected monthly from 10 sites with different levels of eutrophication, from October 2003 to April 2005. Some abiotic factors, such as pH, temperature, conductivity and dissolved oxygen were simultaneously measured in 20 cm deep water at each site. The leaf litter samples were washed in laboratory, cut into 1 cm² pieces and incubated in Petri dishes containing distilled sterile water for five to seven days at 15 °C to 20 °C. Twenty-four aquatic Hyphomycete species were identified, with predominance of Anguillospora crassa Ingold, Lunulospora curvula Ingold, Tetrachaetum elegans Ingold and Camposporium pellucidum... |

Considered as one of the most biodiverse biomes, the Amazon has a featured role in the discovery of new species of plants, animals and microorganisms, which may be important for the functionality of different ecosystems. However, studies on the impacts resulted from changes in the Amazon land use on microbial communities and their functions are still limited. In this context, the soil fungal diversity can act as an important indicator of environmental stress caused by land use of the Amazon. This study describes changes in soil fungal communities caused by different systems of land use (primary forest, secondary forest, agroforestry, agriculture and pasture). Communities were observed in each of the areas using denaturing gradient gel electrophoresis... |
