Abstract
In this study seven new species of the Botryosphaeriaceae are described from baobab (Adansonia gibbosa) and surrounding endemic tree species growing in the Kimberley region of northwestern Australia. Members of the Botryosphaeriaceae were predominantly endophytes isolated from apparently healthy sapwood and bark of endemic trees; others were isolated from dying branches. Phylogenetic analyses of ITS and EF1-α sequence data revealed seven new species: Dothiorella longicollis, Fusicoccum ramosum, Lasiodiplodia margaritacea, Neoscytalidium novaehollandiae, Pseudofusicoccum adansoniae, P. ardesiacum and P. kimberleyense.
We thank Dr H.F. Glen (Natal Herbarium. P.O. Box 52099, Berea Road, Durban, 4007, South Africa) for providing Latin descriptions and Monique Sakalidis for assisting us in making some of the primary isolations. In Australia this project was financially support in part by the ARC Discovery project DP0664334 for a sabbatical research project of Michael J. Wingfield. Portions of the research conducted in South Africa were supported financially by the National Research Foundation (NRF), members of the Tree Protection Co-operative Programme, the THRIP initiative of the Department of Trade and Industry as well as the Department of Science and Technology/National Research Foundation Centre of Excellence in Tree Health Biotechnology (CTHB).
