Abstract
A common leaf spot disease occurring on Eucalyptus cladocalyx and E. lehmannii in the Western Cape Province of South Africa is known from literature to be caused by the fungus Coniothyrium ovatum, which is a pathogen native to several eucalypts in Australia. Recent collections have shown, however, that Australian material identified as C. ovatum was morphologically and phylogenetically distinct from the South African specimens, and that all these taxa would be better accommodated in the genus Teratosphaeria. South African material previously identified as C. ovatum, were found to represent two species that co-occur in the same leaf spots, described here as T. verrucosa and T. juvenalis. Furthermore, a fresh collection of T. ovata from E. phoenicea in Australia, is distinguished morphologically and phylogenetically from similar, newly described taxa such as T. caesia on E. caesia, and T. veloci on E. miniata. Although these leaf pathogens appear to be of minor economical importance, they are morphologically similar to two serious eucalypt canker pathogens, namely T. zuluensis and T. gauchensis, which predominantly cause stem cankers, but could also be found occurring in leaf spots on their own, or in association with some of the other species treated here. Further research is required, therefore, to devise molecular detection techniques for these taxa in an attempt to rapidly distinguish the minor pathogens from the more serious quarantine pathogens that co-occur on leaf material.
