Abstract
The discovery of Cryphonectriaceae and more specifically species related to the Eucalyptus canker pathogen Chrysoporthe cubensis on shrubs and trees in the Melastomataceae has depended our understanding of important and potentially globally threatening tree pathogens. Recent isolations of Cryphonectriaceae associated with cankers on Tibouchina spp. in Brazil gave rise to an apparently underscribed species of Chrysoporthe associated with stem and branch cankers that lead to tree death. Cultures of this fungus were subjected to phylogenetic studies based on sequences for the ITS and β-tubulin gene regions. These analyses revealed a novel taxon that is described here as Chrysoporthe puriensis sp. nov. that included both sexual and asexual states. Isolates of Chr. puriensis from different states in Brazil were subjected to population genetic analyses using microsattelite markers The analyses revealed high gene and genotypic diversity (G=100%) for the fungus suggesting that it is native in Brazil. Pathogenicity tests on two species of Tibouchina (T. granulosa, T. heteromalla) and hybrids of Eucalyptus grandis x E. urophylla showed that Chr. puriensis is able to infect and cause disease on all of these trees. It is clearly not only a threat to native Tibouchina spp. where environmental conditions are conducive to disease development but are also potentially threatening to non-native Eucalyptus spp. that form the basis of a major plantation forest industry.
