Scientific Description
Habit and structure. Thallus erect, pale green, to 5 mm tall, epilithic, with a terete stalk. Attachment by digitate processes arising from the base of the stalk. Stalk cylindrical, becoming broader distally, to 1.5 mm long and 450 μm diam., smooth below but with 10–15 μm thick corrugations distally. Gametangial whorl 1.7–2.3 mm wide, with 13 or 14 rays, these deltoid with flat to rounded apices, to 650–850 μm long and 350–400 μm wide distally, attached laterally to form a flattened disc. Gametangial cysts filling rays when mature, spherical, thick-walled, 80–90 μm diam.
Distribution. Widespread in tropical and subtropical seas. In W.A. known only from Scott Reef, but probably often overlooked due to its small size.
Habitat. Epilithic in the intertidal and shallow subtidal.
