As reported in the International Journal of Systematic and Evolutionary Microbiology, a
newly-discovered bacterium named Candidatus phytoplasma dypsidis has been found to
causeafatalwiltdisease.
In 2016, several ornamental palms within a conservatory in the Cairns Botanic Gardens,
Queensland, died mysteriously. A sample was taken from one of the diseased plants and
investigated by Dr. Richard Davis and colleagues from the Australian Government
Department of Agriculture, Water and the Environment, and state and local government.

"At first we thought it was most likely an unrelated fungal disease. Almost as an
afterthought, I suggested we screen for phytoplasma because there are some very bad
phytoplasma diseases of palms moving around the world, including in neighboring Papua
