Entyloma bidentis is one of four species of Entyloma that has been reported on Bidens in the tropics and subtropics (Vánky, 2003: 5). It has often been mistaken for E. guaraniticum Speg., which has not been found in Australia. The sorus morphology serves as a good differentiating character, sori being flat in E. bidentis and bullate (cup-shaped) in E. guaraniticum.
