Abstract

Species of Mycosphaerella and their anamorphs represent serious pathogens of two phyllodenous species of Acacia, A. mangium and A. crassicarpa. In recent years, these fungi have been collected during surveys in South America and South-East Asia, where these trees are widely planted as exotics. In this study, the Mycosphaerella spp. and their anamorphs were identified based on morphological and cultural characteristics. Identifications were confirmed using comparisons of DNA sequences for the internal transcribed spacer (ITS1 & ITS2), the 5.8S rRNA gene, elongation factor 1-a, histone 3, actin and calmodulin gene regions. The data revealed six new taxa, of which three are named in this study, along with their anamorphs. Cercospora acaciae-mangii, which is morphologically part of the C. apii sensu lato species complex, is distinguished based on its distinct phylogeny. Mycosphaerella acaciigena, collected in Venezuela, is distinguished from M. konae and M. heimii, and described as new. Mycosphaerella thailandica, a new species occurring on Acacia and Musa, is shown to a sibling species to M. colombiensis, a foliar pathogen of Eucalyptus. Mycosphaerella citri, an important leaf and fruit pathogen of Citrus (Rutaceae), is shown to also occur on Musa (Musaceae) and Acacia (Leguminosae).
