Corallum turbinate or sub=
cylindrical, having transverse septa in
the form of inverted cones set one
within the other; rays or lamella very
thin numerous and denticulate. -
In weathered specimens the transverse
septa often project beyond the sides of the
coral above, and the whole appears
somewhat like a series of inverted cones.
The weathered surfaces have sometimes
the appearance of cystiphyllum, from
the irregular meeting of the upper and
under surfaces of the successive
transverse septa.

[Gr?] conos a cone & phyllon a leaf.
