Cystocarp development of Scinaia interrupta. a Three-celled carpogonial branch. b Developed carpogonial branch showing the basal cell (B) developing the initial pericarp (arrowhead), the hypogynous cell (H) with the one-celled branch (SF1) and two-celled branch (SF2) sterile filaments and the carpogonium (C). c Mature carpogonial branch showing the trichogyne (arrowhead) attached to the carpogonium (C). d Immature cystocarp surrounded by the multilayered pericarp (arrow) and rhizoidal filaments (arrowheads) growing from basal cell. e Young cystocarp showing gonimoblast (arrowhead) arising directly from the carpogonium (C). f Developing cystocarp showing a fusion cell with hypogynous branches (arrowhead). g Pear-shaped cystocarp showing the fusion cell (arrow), a developed pericarp (P) and rhizoidal filaments (arrowheads). h Cystocarp showing a fusion cell including the lower cells of the gonimoblast filaments (arrowhead). i Spherical mature cystocarp showing rhizoidal filaments (arrowhead)
