Reproduction. Monoecious or dioecious. Spermatangial cavities 300–350 µm in diameter; spermatangia 6–8 × 4–6 µm. Carpogonial branch basal cell with 4 or 5 small-celled branches; hypogynous cell with 3 or 4 branches of nutritive cells. Cystocarps spherical to slightly flattened, 400–500 µm in diameter. Gonimoblast filaments partially lining pericarp base. Carposporangia 45–65 × 26–40 µm. Paraphyses 3- or 4-celled, projecting from inner face of the pericarp.
