ABSTRACTThe study was conducted to evaluate the Tetranichus urticae development and reproduction in commercial Carica papaya cultivars.

(Freshwater hyphomycetes in a preserved insular system from Brazil: first records at Parque Estadual da Ilha do Cardoso, municipality of Cananéia, São Paulo State). To survey freshwater hyphomycetes from insular water bodies at the Parque Estadual da Ilha do Cardoso State Park, in Cananéia municipality, São Paulo State, Brazil, submerged mixed leaf litter samples were collected from six sites from June 2012 to February 2013. The samples were taken to the laboratory and incubated in Petri dishes containing sterile distilled water at room temperature (20oC). From the 5th day on, until at least one month, fragments of the leaf litter samples were examined under the microscope, resulting in the morphological identification of 33 taxa. Among those, two are new records for the state of São Paulo and four for Brazil. Descriptions and pictures of each new record are presented.

Campylospora brasiliensis is a new freshwater fungus that has been collected from submerged mixed leaf litter in the Brazilian Atlantic Rainforest. A molecular phylogenetic analysis based on ITS sequences of the rDNA reveals it as a new species. Comparison with other species of Campylospora is provided.

Clathrosporium retortum sp. nov., collected on submerged mixed leaf litter samples at Ilha do Cardoso State Park, São Paulo state, Brazil, is described based on morphological and molecular data. The fungus is characterized by forming whitish, dense, subglobose to irregular propagules, hyaline to subhyaline when young, subhyaline to dark brown at maturity, that are formed by densely interwoven conidial filaments with each conidial cell repeatedly branching bilaterally or occasionally unilaterally. Phylogenetic analyses using partial LSU nrDNA sequence data suggest that C. retortum belongs in the Sordariomycetes (Ascomycota) where it forms a well-supported clade with Clohesia corticola in the Sordariomycetidae, but its ordinal or familial placement remains unresolved. Its phylogenetic placement confirms the polyphyletic nature of aeroaquatic fungi like Clathrosporium, as it was distantly related to one available sequence in GenBank named as C. intricatum, the type species, which is phylogenetically related to the Helotiales (Leotiomycetes). However, due to lack of authenticity of the identity of this sequence with the type specimen of C. intricatum, a broad concept of Clathrosporium is tentatively adopted here to accommodate the present fungus instead of introducing a new genus. Beverwykella clathrata, Helicoön septatissimum and Peyronelina glomerulata are recorded for the first time from Brazil. Cancellidium applanatum and Candelabrum brocchiatum are new records for the state of São Paulo.

-(Diversity of conidial fungi and some abiotic variables of the water after the reopening of the Pirarungaua stream in the Jardim Botânico, São Paulo, São Paulo State, Brazil). To evaluate the fungal diversity in the Pirarungaua stream reopened after remaining channeled about 40 years in the Botanical Garden of São Paulo, Brazil, two experiments in the cold and dry season and two in the hot and rainy season were performed. Leaves of Tibouchina pulchra Cogn and mixed leaf litter were confined in nylon litter bags, submerged and collected monthly, together with free leaf litter samples. Some abiotic factors were measured in the water. The leaves were fragmented, incubated in sterile water at 22 ºC and microscopically analyzed. We identified 33 conidial fungal taxa, among which, 23 are new to this area. Comparing seasons, the similarity of the mycota of confined T. pulchra leaves corresponded to 39% and to 56% regarding the confined mixed leaf litter. Similarities of 48-50% occurred between the mycota of confined and free leaf litter samples. Confined leaves showed a tendency to support higher numbers of species, whereas some rare fungi like Ulocoryphus mastigophorus Michaelides L. Hunter & W.B Kendr were more frequent in free leaf litter. Based on the results, it is recommended to monitor the limnological conditions of the stream and to promote awareness among the local population and visitors about the importance of a water body, even artificial, for the establishment of microclimatic features, and for the biodiversity of fungi.

Para avaliar a diversidade de fungos no córrego Pirarungaua, reaberto após ter permanecido canalizado por cerca de 40 anos no Jardim Botânico de São Paulo, Brasil, foram realizados dois experimentos nas estações frias e secas e duas nas estações quentes e chuvosas. Folhas de Tibouchina pulchra Cogn e folhedo misto foram confinados em sacos de tela de nylon, submersas e coletadas mensalmente, juntamente com amostras de folhedo livre submerso. Alguns fatores abióticos foram medidos na água. As folhas foram fragmentadas, incubadas em água esterilizada, a 22 ºC e microscopicamente analisadas, identificando-se 35 táxons de fungos conidiais, entre os quais 23 são novos para a área. Comparando as estações climáticas, a similaridade da micota confinada de T. pulchra correspondeu a 38% e a 56% com relação ao folhedo misto confinado. As folhas confinadas mostraram a tendência de oferecer suporte a maior número de espécies, enquanto alguns fungos raros como Ulocoryphus mastigophorus Michaelides L. Hunter & W.B Kendr foram mais frequentes no folhedo livre. Com base nos resultados é recomendado o monitoramento das condições limnológicas do córrego e conscientização da população local e dos visitantes sobre a importância que um corpo d' água, mesmo art...
