Ceratocystis cacaofunesta Ceratocystis cacaofunesta Ceratocystis cacaofunesta is an ascomycete fungus that causes a wilt disease in cacao trees. It has led to significant economic losses in Latin America. Once considered to be a form of "Ceratocystis fimbriata", the fungus was described as a new species in 2005. The specific epithet "cacaofunesta" means "cacao-killing". Two closely related sublineages exist within this species, one centered in western Ecuador and the other containing isolates from Brazil, Colombia and Costa Rica. The disease known as "Ceratocystis wilt of cacao" (or "Mal de machete") is a serious disease of the cocoa tree ("Theobroma cacao") in Latin America.
