Description: |
Thallus up to 7.0 mm tall, dark-green to whitish, erect, delicate, lightly calcified, composed of a peduncle bearing a single disc of gametangial rays; attached to the substrate by a holdfast with a series of digitate lobes. Peduncle simple, not ramified, cylindrical, transversally corrugated, 3-6 mm long. Disc of gametangial rays, when mature, compound, flat, 3.05.0 mm diam., with 18-23 rays. Disc rays united laterally by calcium carbonate, but free at base, cuneiform, 1500.0-2200.0 μm long × 650.0-880.0 μm wide at apex and 120.0-240.0 μm wide at base; ray apices smooth, obtuse to emarginate. Upper corona situated at base of the rays, rounded, 60.0-80.0 μm diam., bearing (4-)5-6(-7) hairs arranged circularly. Lower corona absent. Fertile gametangial rays bearing approximately 50-60 cysts per ray; cysts globose, 100.0-120.0 μm diam. |
