Odonthalia Lyngbye 1819
Thalli erect, freely branched, with several long, terete to markedly flattened branches, these with or without midrib. Branches basically polysiphonous, distichous, soon heavily corticated by repeated division of the 4 pericentral cells. Tetrasporangia in simple branchlets, these often borne in clusters; 2 opposite pericentral cells of each primary segment producing tetrahedrally divided tetrasporangium. Spermatangia covering surface of short, simple branchlets. Cystocarps clustered on tufted axillary branchlets or borne alternately and distichously on subultimate ramuli.
