These fungi are known to undergo host jumps or shifts. In this study, fruiting structures resembling those of Cryphonectriaceae were collected and isolated from dying branches of Syzygium cordatum and root collars of Heteropyxis natalensis in South Africa, and from cankers on the bark of Tibouchina grandifolia in La R?union. A phylogenetic species concept was used to identify these fungi using partial sequences of the Large Subunit and Internal Transcribed Spacer regions of nuclear ribosomal DNA, and two regions of the β-tubulin gene. The results revealed a new genus and species in the Cryphonectriaceae from South Africa that was named Myrtonectria myrtacearum. Two new species of Celoporthe were described from the La R?union collections, Celoporthe borbonica sp. nov. and Celoporthe tibouchinae sp. nov. The new taxa were mildly pathogenic in pathogenicity tests on a clone of Eucalyptus grandis. Similar to other related taxa in the Cryphonectriaceae, they appear to be endophytes and latent pathogens that could threaten Eucalyptus forestry in the future. } }
