FIGURES 2–6. Vegetative features of Sporolithon yoneshigueae. 2. General morphology of the holotype (RB 569425) showing a lumpy to fruticose growth-form. Scale bar = 3 cm. 3. General morphology of a paratype (RB 505770) showing a warty growth-form. Scale bar = 4 cm. 4. Vertical section of the inner thallus showing the monomerous, plumose (non-coaxial) internal construction (RB 569425). Scale bar = 150 μm. 5. Magnified view of the outer thallus showing a flared epithallial cell (e) and a squat subepithallial initials (i) (RB 569425). Scale bar = 10 μm. 6.
