A preliminary study to identify and distinguish southern tropical populations of from oil palm via mating assays, sequence data, and microsatellite markers.

Morphological studies suggest that the major pathogen causing basal stem rot of oil palm in Papua New Guinea and Solomon Islands is . This study presents the first evidence for conspecificity of from four countries where basal stem rot is prevalent. Seventy-three dikaryotic isolates of from Indonesia, Malaysia, Papua New Guinea, and Solomon Islands were studied via mating tests, analyses of nuc internal transcribed spacer ITS1-5.
