Original Diagnosis [English]

« Cylindrical calcareous bodies often tapered or restricted at the base and top. A few are broadly rounded at the top. They appear to have grown one above the other like a string of sausages. A few show budding or branching.
The plant probably developed extended fronds, each composed of many segments somewhat similar to the modern Cymopolia barbata HARVEY. The fossils represent the individual segments.
The central stem is relatively narrow (about 1/4 to 1/5 width or the entire fossils). Primary branches perpendicular to the axis of the stem, except at ends where they are inclined. Primary branches in alternating annular rows. Secondary branches, small, and steeply inclined to the primary branches bending so tips are approximately parallel to outer surface. Sporangia large, nearly spherical, attached to main stem. They occur in vertical rows separated by primary branches. These vertical rows alternate in position, so that in both vertical and annular rows, there is an alternation of primary branches and sporangia. The tapering ends of the thallus appear to contain only branches, no sporangia. » (JOHNSON, 1954).
