Endoplura jejuensis sp. nov. and Endoplura koreana sp. nov. (Ralfsiales, Phaeophyceae) from Korea based on molecular and morphological analyses

The crustose brown algal genus Endoplura has been known as a monotypic characterized by its intercalary plurangial reproductive structures composed of 2–4 separate parallel filaments terminated 2–5 sterile cells and containing several to many chloroplasts per cell. In this study, jejuensis sp. nov. E. koreana from Korea are newly described based on molecular morphological analyses. Our phylogenetic analyses the rbcL gene reveal that placed in same clade with “E. aurea” Japan strong bootstrap supporting value. is small light dark thalli less than 1 cm diameter, tufts hairs arising basal disc, plurangia mostly two cells, sessile unangia each single paraphysis. distinguished olive or yellowish-brown up 3 apical parts erect filaments, 2–8 1–2 paraphyses. studies also show specimens may be recognized different species other species.
