The aim of this study was to survey for Ceratocystis spp., and their possible insect associates on eucalypts in Australia and thus, to establish a foundation of knowledge regarding these fungi on the continent. Collections were made in three states of Australia from wounds on trees, as well as from nitidulid beetles associated with these wounds. Ceratocystis spp. were identified based on morphology and multigene sequence comparisons. Of the 54 isolates obtained, two previously unknown species of Ceratocystis were found and these are described here as C. corymbiicola sp. nov. and C. tyalla sp. nov. Furthermore, the distribution of C. pirilliformis is expanded to include Eucalyptus spp. in Tasmania.en© Springer Science+Business Media B.V. 2011.
