Description
The cormus in the massive holotype is delicate, formed of large, irregular and loosely anastomosed tubes. In some parts of the cormus, a thin cortex can be seen. Cells with granules are present. The skeleton has no special organization. It comprises equiangular and equiradiate triactines. Actines are conical and sharp, and slightly undulated at the tip.
