“…More recently, Q. cyanescens was found to be associated with cankers on C. calophylla and C. ficifolia in combination with Q. pitereka in Western Australia (Paap et al ., 2008); in that study pathogenicity trials confirmed that Q. cyanescens was non‐pathogenic to Corymbia spp. This fungus has also been identified from human skin and tissue samples (de Hoog & de Vries, 1973), as well as being associated with processed oats (Da Silva et al ., 1999). The presence of Q. cyanescens in both plantations and native spotted gum trees is of interest, but there currently appears to be no damage to tree health or wood quality.…”

This study aimed to determine which species of Quambalaria are associated with shoot blight symptoms on Corymbia spp. An additional aim was to determine the presence and impact of quambalaria shoot blight on Eucalyptus species used in plantation development in subtropical and tropical regions of eastern Australia. Surveys identified three Quambalaria spp. -Q. pitereka , Q. eucalypti and Q. cyanescens -from native and plantation eucalypts, as well as amenity plantings, including the first confirmed report of Q. eucalypti from Eucalyptus plantations in Australia. Symptom descriptions and morphological studies were coupled with phylogenetic studies using ITS rDNA sequence data. Quambalaria pitereka was the causal agent of blight symptoms on species and hybrids in the Corymbia complex. Quambalaria eucalypti was identified from Eucalyptus species and a single Corymbia hybrid. Quambalaria cyanescens was detected from native and plantation Corymbia spp.

RESUMOOs fungos passaram a receber maior atenção como contaminantes de água potável, devido algumas doenças estarem relacionadas a esses microrganismos e ao abastecimento inadequado, principalmente em populações ribeirinhas. Este trabalho verificou a presença de fungos na água de consumo da comunidade ribeirinha, Lago do Limão, Iranduba -AM, e avaliou o perfil de patogenicidade dos fungos isolados. As espécies fúngicas isoladas foram identificadas fenotipicamente e geneticamente. A avaliação dos fungos, quanto ao seu potencial de patogenicidade, incluiu: Crescimento a 37°C, Produção de Ureases e Proteases. Como resultados, foram isoladas 101 culturas de diferentes gêneros da subdivisão Deuteromycotina. Os gêneros isolados de maior frequência foram Aspergillus spp (41,6%), Penicillium spp (19,8%) e Trichoderma spp. (27,7%). Quanto aos parâmetros de patogenicidade, verificou-se que 95% das amostras apresentaram positividade quando incubadas a 37ºC; 66,3% em meio Ágar Christensen e 58,4% no teste de Proteases. Há escassez de trabalhos que abordam a patogenicidade dos fungos presentes na água, principalmente, em água consumida pelas comunidades ribeirinhas. Espera-se que os resultados deste trabalho possam subsidiar a legislação brasileira estabelecer limites de fungos presentes em água potável.

This study verified the presence of fungi in the water consumed by the riverside community of Lake Lemon, Iranduba, AM and assessed the pathogenicity of isolated fungi. The isolated fungal species were identified phenotypically and genetically. Evaluation of the pathogenic potential of the fungi included: growth at 37°C, and the production of urease and proteases. As a result, 101 cultures of different genera belonging to the Deuteromycotina
