“…Most crustose brown algae in Korea have traditionally been identified mainly as Ralfsia or Neoralfsia species based on their morphology (Lee and Kang 1986, Lee 2008, Keum 2010. However, recent research by Oteng'o et al (2021Oteng'o et al ( , 2022 These findings showed the possibility that Korea may be one of the hotspots for crustose brown algal biodiversity.…”

The crustose brown algal family Ralfsiaceae comprises four genera: Analipus, Endoplura, Heteroralfsia, and Ralfsia. This study provides a detailed description of Fissipedicella orientalis gen. et sp. nov. based on molecular and morphological analyses. Our phylogenetic analyses from rbcL and concatenated dataset (rbcL + 5′ region of cytochrome c oxidase subunit I [COI-5P]) reveal that specimens collected in Korea are nested in a distinct new clade within Ralfsiaceae with robust bootstrap support and Bayesian posterior probabilities. The sequence divergences for rbcL and COI-5P between F. orientalis and other genera within Ralfsiaceae are 7.4–10.1 and 17.5–21.2%, respectively. Fissipedicella orientalis is characterized by crustose thalli with a hypothallial basal layer and erect perithallial filaments, tufts of hairs in pits, a single chloroplast per cell, plurangia with 1–3 sterile cells, and unangia on stalks composed of 1–6 vertically or obliquely cleaved cells. We propose that F. orientalis can be recognized as a new genus-level taxon within Ralfsiaceae, even though a single species represents it. Our new genus, Fissipedicella, is distinguished from the other members within the Ralfsiaceae by the type of thallus, the number of chloroplasts and tufts of hairs in pits, and the development of unangia.

Based on morphological and molecular analyses, five families have been recognized within the crustose brown algal order Ralfsiales. Our morphological and molecular sequence data were used to assess the establishment and phylogenetic relationship of Sungminia gen. nov. Phylogenies based on rbcL and concatenated rbcL and COI-5P genes support the recognition of Sungminia composed of three distinct lineages, Sungminia gladiata sp. nov., S. pyriformis sp. nov., and S. asiatica sp. nov. We consider that the Sungminia group is clearly distinct at the family level and propose to place Sungminia in a new family, the Sungminiaceae fam. Nov. Our phylogenetic analyses show that the Sungminiaceae forms a strongly supported monophyletic clade with probable sister relationship to the Mesosporaceae. The Sungminiaceae is characterized by perithallial erect filaments moderately adhered, the rod-shaped perithallial erect filaments, plurangia terminated with single sterile cell, and unangia terminally inserted on 1-2 celled stalk that is lateral-basal or sessile to a paraphysis.
