General Environment
This is a marine species.
Description
Thalli to 20 cm high, brownish-rose to dark red, with light to moderate calcification. Branching alternate to irregularly alternate, sometimes opposite above, axes 1.0-3.0 mm diam. Ultimate branchlets often pectinate or secund. Medullary filaments 30-50 µm diam. Cortical fascicles 3-4 times irregularly dichotomous, occasionally with secund branching. Overall filament length 360-440 µm. Proximal cells of the cortical filaments 6-19 µm diam. and 23-52 µm long, upper cells 6.0-14.5 µm diam. and 10.5-33.0 µm long, apical cells 7-12 µm diam. and 11-24 µm long. Gametophytes dioecious, carpogonial branches straight to slightly curved, 15.0-22.5 ?m diam. and 45-64 µm long. Sterile filaments form from the supporting cell of the carpogonial branch, the involucre being weakly developed (or not a true involucre as the filaments do not surround the gonimoblast but rather, spread horizontally as in a "nest" or "collar"). Carposporophytes 120-200 µm diam.; carposporangia 24 ?m long and 10 µm diam. Spermatangia occur in dense compound sori, borne of spermatangial supporting cells cut off laterally from upper regions (usually the uppermost three cells) of cortical filaments. Tetrasporangia unknown.
