| 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. |

| Rhizosphere soil samples were collected in a semiarid area, in the region of the São Francisco River valley, Petrolina, Pernambuco state, Brazil, to study the diversity of filamentous fungi in a soil cultivated with melon (Cucumis melo L. cv. Gold Mine) and receiving different organic amendments: Treatment 1 (control, without organic compost); T2 (77% coconut fiber, 20% goat manure and 3% K2SO4); T3 (10% Ricinus communis leaves and stems, 50% Pennisetum purpureum leaves and 40% goat manure); T4 (77% coconut fiber, 20% goat manure and 3% termophosphate); T5 (47% Pennisetum purpureum leaves, 50% goat manure and 3% K2SO4); and T6 (57% Pennisetum purpureum leaves, 40% goat manure and 3% termophosphate). Fungal isolation was carried out by the serial dilution... |

| The survey of Agaricaceae in areas of the Atlantic Forest in the metropolitan region of Recife, state of Pernambuco, Brazil, revealed the presence of nine species: Agaricus aff. parasilvaticus Heinem., A. purpurellus (F.H. Møller) F.H. Møller, A. rufoaurantiacus Heinem., Leucoagaricus sulphurellus (Pegler) B.P. Akers, Leucocoprinus cretaceus (Bull.: Fr.) Locq., L. fragilissimus (Ravenel) Pat., Lepiota elaiophylla Vellinga & Huijser, L. erythrosticta (Berk. & Broome) Sacc. and Micropsalliota brunneosperma (Singer) Pegler. A key for identification of these species, descriptions, drawings and remarks are provided. Micropsalliota brunneosperma is reported for the first time for Brazil. |

| ABSTRACT The diversity of endophytic fungi in healthy coconut palm leaves (Cocos nucifera) was assessed by analyzing fungal isolates from three coconut cultivars (yellow dwarf, green dwarf, and a hybrid cultivar PB121) used agriculturally in Brazil. The influence of season (rainy or dry) on the endophytic fungal community was also analyzed. Overall, 318 fungal isolates were obtained from 972 coconut leaf fragments. The rDNA ITS region was sequenced from representative species of the isolated endophytic fungi and the most common species identified were Nigrospora oryzae, Pestalotiopsis sp., and Zasmidium musae. The alpha diversity of the endophytic fungi was also calculated. Nonmetric multidimensional scaling (NMDS) ordination and permutational analysis of... |

| O solo é considerado um dos principais hábitats para a população de microrganismos, dentre os quais estão os fungos. A região de Xingó é caracterizada por apresentar ecossistema típico de Caatinga. Com objetivo de isolar e identificar fungos filamentosos na região Xingó, utilizou-se amostras de solo coletadas nos municípios de Canindé de São Francisco (SE), Olho D'água do Casado (AL) e Piranhas (AL), durante o período chuvoso (maio e julho/2000) e de estiagem (março/2001), tanto na superfície do solo quanto a 20 cm de profundidade. Foram identificados 96 táxons pertencentes a oito espécies de Ascomycota, oito espécies de Zygomycota e 80 anamorfos, sendo uma espécie de Coelomycetes e 79 espécies de Hyphomycetes. Penicillium e Aspergillus foram os gêneros... |

| Trichosporon has been reported as a remarkable emerging pathogen and usually occurs in imunodrepressed patients. An oropharyngeal secretion sample was collected from a patient with AIDS, at the Sector of Infectious and Parasitic Diseases, Osvaldo Cruz University Hospital, Pernambuco State, Brazil. No yeast cells or arthroconidia were observed in the direct exam, but a culture was positive for Trichosporon pullulans, which is being reported in an AIDS patient for the first time. |

| In order to evaluate the pathogenicity of yeasts of medical importance, 15 strains stocked in mineral oil at the URM Culture Collection of the Department of Mycology, Biological Sciences Centre, Federal University of Pernambuco and 15 fresh strains isolated from AIDS patients interned at the Clinical Hospital, Centre of Health Sciences, Federal University of Pernambuco, were selected. As pathogenicity characteristics, the ability to grow at 37ºC and production of phospolipase and proteinase were tested. All samples grew at 37ºC and exhibited proteinase activity. However when tested on solid medium, the proteinase activity was negative. Among 15 stocked samples, 13 (86.66%) were phospholipase positive and two (13.34%) were phospholipase negative. From the... |

| Thirty-eight taxa of Zygomycetes distributed in 15 genera were recorded from tapir (Tapirus terrestris), camel (Camelus bactrianus), horse (Equus caballus), deer (Cervus elaphus), agouti (Dasyprocta aguti), donkey (Equus asinus), llama (Llama glama) and waterbuck (Kobus ellipsiprymnus) dung collected at the Reserva Ecológica de Dois Irmãos located in Recife, State of Pernambuco, Northeast Brazil. The samples were collected on a monthly basis from June 2005 to May 2006, taken to the laboratory and incubated in moist chambers. Higher number of taxa was observed in the excrements of tapir, followed by deer and donkey. The highest number of species was detected for Mucor, followed by Pilobolus. Statistical analyses showed significant differences in richness of... |

| The aim of this work was to isolate and identify yeasts from sand and sea water collected in two beaches of Olinda, Pernambuco state, Brazil. Thirty two samples of both sand and water in both beaches were obtained in the dry (December 2000 and February 2001) and rainy (June and July 2001) seasons. Two hundred and ninety two strains of yeast were obtained, and they belonged to four genera and 31 species. Candida was the most prevalent genus. Candida catenulata, C. fenica, C. sake, Brettanomyces bruxelenses and Rhodotorula mucilaginosa were the most commonly found species in both beaches Bairro Novo and Casa Caiada. |
