Hupercyathelus differs in possessing an outer wall with downwardly projecting canals and bearing supplementary independent microporous sheath externally and an inner wall with several rows of canals. Porocyathellus differs in possessing several rows of canals on the inner wall. Vologdinocyathellus differs in possessing an inner wall with straight canals.
