Cross sections 250 – 295 μm thick, with medulla consisting of one layer of large, rounded cells, 66.7 – 74.1 μm long, 85.2 – 92.6 μm wide, and one outer layer of pigmented, rounded to irregular small cells, 11.1 – 22.1 μm long, 7.4 – 22.2 μm wide (Fig. 3 G). Central axial filament evident in surface view, consisting of elongate cells (arrows), 20 – 40 μm long × 8 – 15 μm wide, surrounded by 2 – 3 layers of medullary cells and one or two layers of rounded cortical cells. (Fig. 3 H). Unicellular hairs not observed. Reproductive characters were not observed.	en	Paiano, Monica O., Fumo, James T., Cabrera, Feresa P., Kosaki, Randall K., Spalding, Heather L., Sherwood, Alison R.

9E5FA436E83AF121FF785D83CF0EFEE0.taxon	etymology	Etymology: — C. yasutakei is named in memory of Mr. Yumi Yasutake, a long-time educator and scientist for the Papahânaumokuâkea Marine National Monument. Through the use of algal pressings as a student activity, Yasutake shared his love of phycology, marine science, and Papahânaumokuâkea with legions of young people throughout the state of Hawai‘i.	en	Paiano, Monica O., Fumo, James T., Cabrera, Feresa P., Kosaki, Randall K., Spalding, Heather L., Sherwood, Alison R.

9E5FA436E837F12FFF785884CBC2FC05.taxon	description	Description: Thalli upright, terete, ranging from 1.2 – 4.5 cm in length (Figs 4 A – C), usually rich red in color when living, drying to a light pink to orange when pressed (Fig 4 A). Thalli are compressed with thorn-like branchlets that are often dichotomously branched at the apices and alternately branched in the mid to basal portions (Figs 4 D – E). Branching most often in three-dimensional space (Figs 4 A – E). In surface view, thallus is composed of small cortical cells, elongated, 4.0 – 7.5 μm in length and 2.0 – 10.8 μm in diameter (Fig 4 F). Axes uniaxial, rounded. Transverse sections 310 – 440 μm in diameter (Figs 4 G – H). Each axial cell surrounded by three to five periaxial cells (Figs 4 G – H), 38 – 45 μm in diameter, surrounded by two to four layers of large, rounded to cuboidal medullary cells, 30 – 98 μm in length and 20 – 60 μm in width. Holdfast not observed. Only sterile plants observed.	en	Paiano, Monica O., Fumo, James T., Cabrera, Feresa P., Kosaki, Randall K., Spalding, Heather L., Sherwood, Alison R.
