Eight broad, simple marginal lappets; oral arms as long as radius of the disk, thick, stiff with densely crenulated margins and numerous small tentacles; adradial canals unbranched; perradial and interradial canals with unbranched primary canal; umbrella margin with few anastomoses.

High abundances of ephyrae during late autumn can be explained by the large number of poly disc scyphistomae preceeding to the appearnace of ephyrae. Budding doesn’t occur in winter months.
