Even though commercially significant, species of eucheuma are difficult to identify without the aid of close scientific examination, as different species may have very similar morphologies. It is assumed that eighteen to twenty species alone fall within the genus Eucheuma, represented by the groups Cottoniformia, Eucheuma, Gelatiformia, and Anaxiferae.
The thallus of Eucheuma ranges from 35 to 74 cm. Branches are brittle to cartilaginous in consistency, ranging from 7 to 9 cm in length, with whorled/spinous branchlets. The cell diameters are as follows: 2-5 µm outer cortexes, 30-196 µm inner cortex and 20-45 µm medulla. Rhizoids of the medulla are present but thylles are absent. Tetrasporangia are zonate with tetraspores ranging from 13 to 36 µm in diameter. Spermatophyte conceptacles range over 350-650 x 300-420 µm with a spermatial diameter of 14-29 µm. Cystocarps and carpospores have not been observed in this species.
