| Para determinar o efeito de fungos micorrízicos arbusculares sobre o crescimento de mudas de maracujazeiro-doce foi conduzido, em casa de vegetação, experimento com delineamento inteiramente casualizado usando cinco tratamentos de inoculação (200 esporos/planta de Acaulospora longula Spain & Schenck, Gigaspora albida Schenck & Smith, Glomus etunicatum Becker & Gerd., Scutellospora heterogama (Nicol. & Gerd.) Walker & Sanders e controle não inoculado), com sete repetições. A cada 20 dias foram avaliados altura e número de folhas e ao final do experimento (90 dias): diâmetro do caule, biomassa, área foliar, colonização micorrízica e densidade de esporos de FMA na rizosfera. A partir de 70 dias foram evidenciadas... |

| We analyzed specimens identified as Amanita muscaria, some recently collected and others already deposited in herbaria, in Brazil. We concluded that two subspecies of A. muscaria occur in Brazil: A. muscaria var. muscaria; and A.muscaria var. flavivolvata. The first taxon was found in association with Castanea sativa, and the second (one specimen only) was found in association with Pinus and Eucalyptus spp. Morphologically, A. muscaria var. flavivolvata is distinguished by a shallower subhymenium and by basidiospores that are more elongated than are those of A. muscaria var. muscaria, which is the more widely known subspecies. We present descriptions, discussions, illustrations and a dichotomous key for these two subspecies. |

| Folhas mortas de Clusia melchiorii Gleason e C. nemorosa G. Mey. foram coletadas bimestralmente na Serra da Jibóia, Bahia, no período de outubro/2005 a junho/2006. As folhas foram lavadas em água corrente e mantidas em câmara-úmida durante 30 dias. As estruturas fúngicas foram coletadas e montadas em lâminas permanentes. São apresentadas descrições e ilustrações de sete novos registros de Hyphomycetes para o Estado da Bahia [Beltrania querna Harkn., Clonostachys compactiuscula (Sacc.) D. Hawksw. & W. Gams, Dictyosporium elegans Corda, Gyrothrix verticiclada (Goid.) S. Hughes & Piroz., Pseudobotrytis terrestris (Timonin) Subram., Sporendocladia bactrospora (W.B. Kendr.) M.J. Wingf. e Stachybotrys parvispora S. Hughes]. |

| The effects of inoculation of sweet passion fruit plants with the arbuscular mycorrhizal (AM) fungus Scutellospora heterogama on the symptoms produced by Meloidogyne incognita race 1 and its reproduction were evaluated in two greenhouse experiments. In the 1st, the M. incognita (5000 eggs/plant) and S. heterogama (200 spores/plant) inoculations were simultaneous; in the 2nd, the nematodes were inoculated 120 days after the fungal inoculation. In both the experiments, 220 days after AM fungal inoculation, plant growth was stimulated by the fungus. In disinfested soil, control seedlings (without S. heterogama) were intolerant to parasitism of M. incognita, while the growth of mycorrhized seedlings was not affected. Sporulation of S. heterogama was negatively... |

| Nineteen taxa of Mucorales, belonging to Absidi, Apophysomyces, Cunninghamella, Fennellomyces, Lichtheimi, Mucor, Mycotypha, Rhizopus and Syncephalastrum were isolated from 36 composite soil samples in three semiarid areas in the State of Pernambuco (Triunfo, Cabrobó and Belém de São Francisco), Northeast Brazil, which are characterized by Caatinga vegetation. Triunfo is preserved, whereas Cabroró and Belém de São Francisco are experiencing low and severe desertification processes, respectively. Mucorales were isolated in Petri dishes in triplicate from 5 mg samples of soil placed on the surface of wheat germ agar plus chloramphenicol and Cercobin [Dimethyl 4,49-(103 phenylene) bis (3-thioallophanate)] medium. The plates were left on a bench at room... |

| With the aim of increasing the knowledge about endophytic fungi, a group of microorganisms with high biotechnological potential and a valuable source of useful metabolites, a survey in leaves of mangrove plants (Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle) was performed at the Itamaracá Island, PE, Brazil. Leaves were collected, during two seasons, dry and rainy, superficially sterilized and fragments maintained in Petri dishes with Potato dextrose agar (PDA) at 28º ± 2º C until isolation of the fungi. Fourty taxa were isolated: 25 species representing 19 genera and 15 morphotypes determined as Mycelia sterilia. Leaves of L. racemosa hosted the highest number of colony forming units (CFU) and taxa. Guignardia sp. and Colletotrichum... |
