FIGURE 5. Phycodrys radicosa (Okamura) Yamada & Inagaki from Korean coast. Female (A–M) and tetrasporic (O–P) reproductive structures. A. Apex of marginal proliferation with procarps (arrowheads). B–G. Development process of immature procarp (cb1–3: cell numbers of carpogonial branch; cbi: carpogonial branch initial; cc: central cell; sc: supporting cell; st1: first sterile-cell group; st1i: first sterile-cell group initial; st2i: second sterile-cell group initial). H–I. Inferior (H) and superior (I) surface views of same point of mature procarp (cp: carpogonium; st2: second sterile-cell group; tr: trichogyne). J–K. Inferior (J) and superior (K) surface views of same point of post-fertilized stage (au: auxiliary cell; cbs: cells in carpogonial branch). L. Cross-section through an immature cystocarp (fu: fusion cell; gi: gonimoblast initial). M. Cross-section through a mature cystocarp. N–O. Surface views of tetrasporangial sori (t: tetrasporangia; ts: tetrasporangial sori). P. Cross-section through a tetrasporangium (ti: tetrasporangial initial). Scale bars: N = 1 mm; M, O = 100 µm; A, L, P = 50 µm; B–20 µm.
