Abstract
A survey of fungal pathogens associated with cane tibouchina Tibouchina herbacea Melastomataceae was conducted in the neotropics concentrated in south and southeastern Brazil and aimed at finding potential biological control agents for this herbaceous invasive weed for introduction into Hawaii Numerous fungal species were found including five cercosporoid fungi Four new taxa are described and illustrated here Passalora tibouchinae Pseudocercospora subsynnematosa Pseudocercospora tibouchinaherbaceae and Pseudocercospora tibouchinicola A phylogenetic analysis of the ITS and TEF1α regions of the three new species of Pseudocercospora was conducted and confirmed their separation as distinct taxa as indicated by morphological and cultural features Additionally Cercospora apii is reported for the first time on T herbacea Among the species of fungi described in this study two appear particularly promising for use in a biological control program because they were found to cause severe disease on T herbacea Passalora tibouchinae and Pseudocercospora subsynnematosa Additional tests including hostspecificity screening will be required in order to confirm this potentialTaxonomical novelty Passalora tibouchinae DF Parreira OL Pereira R W Barreto Pseudocercospora subsynnematosa DF Parreira DJ Soares R W Barreto Pseudocercospora tibouchinaherbaceae DF Parreira RW Barreto Pseudocercospora tibouchinicola DF Parreira DJ Soares R W Barreto
