TRIBE CORALLINEAE Areschoug 1852: 509

Phylum Rhodophyta – Class Florideophyceae – Order Corallinales – Family Corallinaceae – Subfamily Corallinoideae

Thallus usually pinnately branched. Intergenicula with (8–) 10–25 (–50) tiers of medullary cells each 50–90 µm long. Fusion cells thin (6–12 µm) and broad (90–300 µm), with carposporangial filaments from margins and/or upper surface; male conceptacles with a broad chamber (350–450 µm), low ceilings and long canal (200–500 µm). Tetrasporangia relatively small, many (>30) per conceptacle, with interspersed paraphyses, conceptacles usually without branches.

KEY TO GENERA OF CORALLINEAE

1. Intergenicula with (8–) 10–20 (–25) tiers of medullary cells. Carposporangial filaments near the margin of fusion cells; male conceptacles with short beaks; tetrasporangial conceptacles seldom bearing branchlets; fertile intergenicula narrow	CORALLINA
1. Intergenicula with 20–50 tiers of medullary cells. Carposporangial filaments over the surface of fusion cells; male conceptacles usually with long beaks; all conceptacles usually bearing branchlets, fertile intergenicula broad	ARTHROCARDIA
