Encyonema cesati is even more lanceolate, apices are rostrate and the central area is larger on the ventral side, as compared to E. evergladianum. Encyonema krammeri has a smaller maximum size, apicies are more rostrate and stria density is higher (25-30 in 10 µm). Encyonema densistriata is similar in shape and size, but possesses a dorsal stigma and more rostrate ends. Encyonema subrostratum has nearly parallel striae of lower density (14-16 in 10 µm). Encyonema guettingeri has a ventrally shifted raphe and less dense striae (12-14 in 10 µm). Encyonema ruttneri has a less pronounced dorsal arch.
