    Summary
    Chaconia clusiae on Clusia cf. palmicida (Clusiaceae) and C. heliconiae on Heliconia psittacorum, H. bihai and Heliconia sp. (Heliconiaceae) are described as new from French Guiana in northern South America. Clusiaceae and Heliconiaceae are new host families for members of Chaconia, Heliconiaceae is the first one from Monocotyledoneae. Chaconia clusiae, C. heliconiae and C. maprouneae formed tuberous to worm-like D-haustoria originating from haustorial mother cells that were part of the intercellular parasitic mycelium. A key to the recognized Chaconia spp. is provided
