Ganoderma orbiforme is a species of polypore fungus that is widespread across southeast Asia. It is a plant pathogen that causes basal stem rot, a disease of the African oil palm (Elaeis guineensis). The fungus was first described scientifically in 1838 by Elias Magnus Fries from collections made in Guinea.Leif Ryvarden transferred it to the genus Ganoderma in 2000. In addition to its type locality, the fungus has also been collected from the Bonin Islands in the Pacific, and from Venezuela and Puerto Rico.Microsatellite markers have been developed to help identify the fungus and study the genetic diversity of G. orbiforme.
