FIGURE 5. Reproductive morphology of Calliblepharis saidana. A. Female thallus (SP470445) with marginal cystocarps. B. Transverse section of an immature cystocarp showing the basal inner nutritive tissue (nt) and gonimoblast filaments (gf) bearing chains of carposporangia (ca). C. Transverse section of a mature cystocarp showing gonimoblast filaments (gf) outwardly producing carposporangia (ca), a reticulum of interconnected filaments (r) and the basal inner nutritive tissue (nt). D. Detail of the pericarp, with sterile transverse filaments (arrows). E. Chains of carposporangia. F. Nonostiolate, mature cystocarp. G. Surface view of a tetrasporangial sorus. H. Transverse section of a tetrasporangial sorus showing two mature tetrasporangia zonately divided.
