Conceptacle pore canals flanked by filaments projecting laterally towards the pore canal; rings of large block-shaped cells absent. Mature conceptacle chambers 170–260 μm diam. and 95–130 μm tall; tetrasporangia 15–25 μm diam. and 40–60 μm long. Gametangial and carposporangial thalli not known from Australia.
