Bismarck palm (Bismarckia nobilis Hildebr. & H. Wendl.) is one of the most sought after palms. A severe disease of Bismarck palm was discovered in Wenchang, Hainan Province, China, in July 2010. The main symptoms were russet to gray-white lesions at the tip of leaflets, and the irregular-shaped lesions surrounded by reddish to brown halos. The lesions gradually extended to base of the compound leaf, and entire infected leaves dried up at the advanced stage. A fungus was consistently obtained on the potato dextrose agar medium and the colonies were grayish white, cottony aerial mycelia, with peach to orange conidial masses. The conidia were hyaline, one-celled, and cylindrical with obtuse to slightly rounded ends. A multi-locus approach was utilized to identify the casual pathogen. Molecular phylogenetic trees were constructed using six combined loci, and strain BWZ2 clustered with the ex-type strains of C. siamense (CBS 112983) in the maximum likelihood phylogenetic tree. The pathogenicity test indicated that typical gray-white lesions surrounded by brown halos were observed on all the inoculated leaflets at 7 days post inoculation. On the basis of the biological characteristics, pathogenicity, and analyses of the concatenated sequences of the ACT, CHS1, GAPDH, HIS, ITS, and TUB2 genes, the causal agent was identified as Colletotrichum siamense Prihastuti, L. Cai & K. D. Hyde. This is the first report of Bismarck palm anthracnose caused by C. siamense.
