Lee, I. K. Lee, H.-G. Choi] Morphology and nuclear small-subunit (SSU) rDNA sequences from Ishige okamurae Yendo and I. sinicola (Setchell et Gardner) Chihara were investigated to describe their species and to infer their phylogenetic relationships within the Chordariales. Ishige okamurae has a narrower frond, a thicker cortical layer, acute apice and rough superficial arrangement in SEM in contrast to I. sinicola. These morphological differences were supported by the partial SSU sequence differences of 28 base pairs between two species. Ishige species were clearly distinguished from other chordarialean taxa by having inconspicuous apical meristematic cells, terminal unilocular sporangia, only coalescent determinate filaments and hairs from cryptostomata. Consistent with morphological observations, our SSU data indicated that Ishige might form an independent lineage with some possible affinities for the early lineage of the Ectocarpales sensu lato.
