Morphological and molecular information of two marine algae collected from Korea is given. One belonging to a green alga, is characterized by small size up to 4 cm high, much branched thalli on all sides, slender and linear branchlets which is constricted near base, axes without prominent branch scars, chloroplasts with a prominent central pyrenoid. The other, as a brown alga, is distinct from other Korean species in having cylindrical elevated projections at all parts of thallus axis, leaves with slightly serrulate margin together with distinct midrib bearing spines and absence to rarely occurred vesicles. In phylogenetic tree based on rbcL sequences, these two species are nested in the same clade with Bryopsis triploramosa and Sargassum polyporum, respectively. In this study, these two species are newly recorded in the Korean marine algal flora based on the morphological and molecular data.
