Última Species of Mycosphaerella and related anamorphs on Eucalyptus leaves from Thailand Naturalis Crous, R. Cheewangkoon: P.W.; Hyde, K.D.; Groenewald, J.Z.; To-anan, C.. Species of Mycosphaerella and their related anamorphs represent potentially serious foliar pathogens of Eucalyptus. The fungi treated in the present study were isolated from symptomatic Eucalyptus leaves collected in Thailand during June –October 2007. Species were initially identified based on morphological and cultural characteristics. Identifications were confirmed using comparisons of DNA sequence data of the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the 28S nrDNA (LSU) regions. To help distinguish species of Pseudocercospora, the dataset was expanded by generating partial sequences of the translation elongation factor 1-α and actin genes. By integrating the morphological and molecular datasets, five new taxa were distinguished, namely...

Ano: 2008 URL: http://www.repository.naturalis.nl/record/532327 Co-occurring species of Teratosphaeria on Eucalyptus Naturalis Crous, P.W.; Groenewald, J.Z.; Summerell, B.A.; Wingfield, B.D.; Wingfield, M.J.. 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 that Australian material identified as C. ovatum is morphologically and phylogenetically distinct from the South African specimens, and that all these taxa would be better accommodated in the genus Teratosphaeria. South African specimens previously identified as C. ovatum were found to represent two species that co-occur in the same leaves and even spots and are described here as T. juvenalis and T. verrucosa. Furthermore, a fresh collection of T. ovata from E. phoenicea...
