Terminal cap made up of 63 to 85 sporangial rays, laterally attached to each other by calcification.Sporangial rays cylindrical-compressed, decreasing in diameter towards the centre of the cap, their terminal wall at the margin of the cap truncate to slightly emarginate. Distinct vertical notches present at the proximal half of the lateral walls of rays. Segments of corona superior 230 to 250 μm long, bearing 6 to 9 hairs or hair scars in an uniseriate row; segments of corona inferior 265 to 280 μm long with rounded, truncate or emarginate outer margins. Spores oval to spherical, up to 98 to 115 μm in diameter. Thalli up to 6 cm in height; the largest species among the genus Acetabularia (Ref. 80758).
