Description
Plants typically appearing as small, hemispherical, brownish-rose clumps across areas of intertidal rock, usually in areas of considerable surf, to 5.0 cm high and 7.5 cm wide. Axes mostly uniform, to 1 mm diam. with moderate to heavy calcification. Branching dichotomous with annular constrictions obvious in the upper portions of the branches. Cortical fascicles composed of 3-5-times dichotomously branched filaments, overall to 240 ?m in length. Apical cortical cells swollen, obpyriform to clavate, 15-21 µm long and 9-12 µm diam., some with apical hairs. Gametophytes dioecious, spermatangia obovate, 2-3 µm diam., formed from stalk cells on the subapical cells of the cortical filaments, either singly or in pairs. Carpogonial branches 3-celled, 65-85 µm long, borne distally on supporting cortical cells. Carpogonial branch cells elongate to ellipsoidal, 7.5-16.5 ?m diam. with basal cells only slightly longer than central cells. Post-fertilization fusion present. Carpogonia narrowly conical, first divisions lateral; fertilized carpogonia issuing opposite gonimoblast initials at distal ends. Involucral filaments not produced. Single, terminal, undivided, elongate-ellipsoid to obovoid carposporangia, 6-14 µm diam. and 19-26 µm long.
