Description
Utricles with 18 dextrally spiralled cells, with no coronula cells; spirals occasionally divided by transverse ridges, shape subglobular to oblate, apical region flattened or depressed, apical pore larger than basal; basal pore sometimes surrounded by 2 bisymmetrical, lip-shaped protuberances. [The most important characters are the number of spiral cells (18) as well as the occasional transverse ridges, which recall Sycidium.]
