“…In the State of São Paulo, the diversity of several groups of fungi is better known because surveys have been done in terrestrial and aquatic environments in some preserved or less affected Atlantic Rainforest in protected areas such as "Reserva Biológica de Paranapiacaba" (1,19,23,25,(55)(56)(57)(58)(59)69), "Parque Estadual da Ilha do Cardoso" (66,67,68,71,72) and "Estação Ecológica da Juréia-Itatins" (2,12,22,42), but also in regions relatively close (10 to 20km) to the center of the city of São Paulo, such as "Represa do Guarapiranga" (14,32,50,51,75) and "Parque Estadual das Fontes do Ipiranga", where the Botanical Institute of São Paulo is located (16,17,20,24,(36)(37)(38)(39)(40)(41)(44)(45)(46)54,70,73).…”

This article presents a survey of fungi obtained from soil, water and mixed leaf litter samples taken from the Atlantic Rainforest in the municipality of Cubatão, in the State of São Paulo, during the years of 1993 to 1995. Using different techniques for the isolation of microscopic fungi, a total of 280 taxa was obtained (66 zoosporic fungi, 40 Mucorales, 45 Glomales, 125 anamorphs, three Ascomycota and one Basidiomycota), with 23 species being reported for the first time in Brazil.

“…Trufem (1990Trufem ( , 1995 encontrou 12 e 13 espécies deste gênero em solos com pH entre 3,5 a 5,8 e sugeriu que essas espécies são mais adaptadas a tais condições, o que indica que os níveis de pH no solo das áreas estudadas favorecem a ocorrência de Acaulospora. Reforçando este fato, Gomes & Trufem (1998) encontraram 10 espécies de Acaulospora e seis de Glomus, num total de 21 espécies de FMA, associadas a solos ácidos (pH 3,2 e 3,4), na Ilha dos Eucaliptos (São Paulo), confirmando a presença de Acaulospora e Glomus em solos com baixo pH. Siqueira (1994) menciona que as espécies de Gigasporaceae são mais comuns em solos ácidos.…”

-(Diversity and infectivity potential of arbuscular mycorrhizal fungi in an area of "caatinga" in the Xingó Region, State of Alagoas, Brazil). The region occupies 2800 km 2 , in the States of Pernambuco, Alagoas, Sergipe and Bahia, and constitutes a preserved part of the Northeastern semi-arid ecosystem. Evaluation of the diversity and density of propagules of arbuscular mycorrhizal fungi (AMF) in the soil, as well as of the mycorrhizal colonization in plants of the area was carried out by sampling of soil and roots during the dry (August/2000) and rainy (March/2001) seasons, in two subareas (Piranhas and Olho d'Água do Casado) in Alagoas. More than 95% of the plants, among the 71 examined, formed arbuscular mycorrhiza (5-80% colonization). Among these 30 phanerogamic species, belonging to 14 families, only Pilosocereus sp. was not colonized. The average percentages of colonization (≅ 16-20%) were similar in both sampling periods. There was an inverse relationship between number of spores and the most probable number (MPN) of infective propagules in the area of Olho d'Água, with lower density of spores (< 2 spores.g -1 of soil) and higher MPN of propagules (4.7 and 11.6 spores.g -1 of soil), in the rainy and dry periods. Number of spores and MPN of propagules were similar in the Piranhas area during the rainy season; in the dry season the number of spores was 1.5 times higher than the MPN. Twenty-four taxa of AMF, mostly of Acaulosporaceae and Glomaceae, were identified. The AMF are well represented, forming mycorrhizal association with most "caatinga" plants, despite the severe climatic limitations of the region.

“…O estabelecimento da associação MA em eucalipto é conhecida há mais de 20 anos, e os benefícios da simbiose têm sido explorados comercialmente (St. John 1980;Coelho et al 1997;Gomes & Trufem 1998;Grazziotti et al 1998;Santos 2001;Santos et al 2001). Santos et al (2001), em estudo realizado com cinco espécies de eucalipto, incluindo E. cloeziana, observaram uma sucessão no tipo de colonização micorrízica, sendo inicialmente dominado por FMA e posteriormente por fungos ectomicorrízicos.…”

RESUMO -(Micorriza arbuscular em plantações de Eucalyptus cloeziana F. Muell no litoral norte da Bahia, Brasil). As micorrizas arbusculares são de longa data conhecidas e exploradas devido à importância ecológica e aos efeitos no crescimento e na nutrição das plantas. Eucalyptus cloeziana F. Muell, particularmente nas áreas em estudo, apresenta comportamento diferenciado quando comparado com outras espécies de eucaliptos, instalando-se em sítios de solos pobres e textura arenosa, com crescimento reduzido, dificuldades para a formação das mudas e problemas nutricionais. Objetivando avaliar a percentagem de colonização radicular e a densidade de esporos de fungos micorrízicos arbusculares em plantações de E. cloeziana, foram realizadas coletas de solo rizosférico e de raízes em 20 áreas, distribuídas em seis municípios do Estado da Bahia, Brasil. Os resultados médios da percentagem de colonização variaram de 10% a 96,66% e a densidade de esporos variou de 3 a 110 esporos/50cm 3 de solo, demonstrando a grande suscetibilidade do E. cloeziana à micorrização. Palavras-chave: Eucalyptus cloeziana, Glomales, colonização radicular, densidade de esporosABSTRACT -(Arbuscular mycorrhiza in Eucalyptus cloeziana F. Muell plantations in the north littoral of Bahia, Brazil). The arbuscular mycorrhizal are known and explored long ago due to the ecological significance and the effects in the growth and nutrition of the plants. Eucalyptus cloeziana F. Muell, particularly in the studied sites, exhibit differenced behaviour when compared with other eucaliptus species, establishing in sites of the poor soils and sandy texture, with reduced growth, difficulty to formation of the seedling and nutritional problems. Aiming to evaluate the percentage of mycorrhizal colonization, as well as the density of arbuscular mycorrhizal fungi spores in E. cloeziana plantations, rhizospheric soil and roots samples were collected in twenty sites, distributed in six municipalities of Bahia state, Brazil. The mean results of percentage root colonization ranged from 10 to 96.66% and spore number ranged from 3 to 110 spores/50cm 3 soil, demonstrating high susceptibility of the E. cloeziana to mycorrhization.
