Asparagopsis svedelii
alga roja, red algae
Plants erect, the terete axes precurrent, alternately branched to 2-3 degrees, bearing radially disposed straight or slightly curved pluriseriate branchlets which are simple or very alternately branched, 0.75-1.30 mm long, 75-100 µ diameter near the base and markedly tapered toward the tips; axes wiry, about 0.75 mm diameter, corticated irregularly, in section showing one large thick-walled axial cell about 180 µ diameter, lying in a considerable cavity which had 5-7 small filaments appressed to the outer wall; cavity surrounded by 3-4 layers of moderately large firm-walled cells and externally a one-layered cortex of chromatophore-bearing cells; gland cells not noticeable on the branchlets; reproduction unknown
