    Description

    Phellinus noxius (Corner) G. H. Cunn is a vastly destructive, fast-growing fungal pathogen that affects a wide range of woody hosts in pan-tropical areas, including Asia, Australia, Africa, and Oceania (Ann et al. 2002; Figure 1) . This pathogen causes brown root-rot disease on cacao, coffee, and rubber, as well as diverse fruit, nut, ornamental, and other native/exotic trees, with little indication of host specificity (Sahashi et al. 2010). Pathogenic symptoms of P. noxius infection can include reduced tree growth, defoliation, and branch dieback; however, P. noxius can survive as a saprophyte by colonizing heartwood and/or other organic matter. Brown root-rot disease can develop over several years, or in some cases, P. noxius infection can cause tree mortality within a year. Understanding the genetic diversity and evolutional history of P. noxius populations worldwide well help assess the evolutionary origins, worldwide movement, and potential ecological differences within P. noxius.
