Branches subcylindrical, branching of equal thickness. Long intervals between branches. Clusters of large cells are conspicuous, The one in the northern most part of this picture might have a crinoid holdfast.

Since there hadn't been any official researches into platteville bryozoan, I would assume this to be a early forerunner of Batostoma fertile as it looks very similar to it but on average smaller. One rock have a different species running parallel but camera couldn't get more details.

I only found this species this year in a new Decorah dig site location. I would had almost tossed it aside if not for the first piece I found which is much longer than the usual rugose decorah twin cities Ordovician bryozoans. On closer inspects it is so different from my Batostoma species. Rarely branching which is very unusual for a rugose bryozoan, very variable wall thickness as seen as under digital microscope. Only found in this one location.
