Description: Thallus a membranous, distromatic blade, light green in color, up to 7.0 cm high and 1.5 cm wide. Blades clavate to lanceolate with smooth, slightly undulating margins. Cells in surface view polygonal, irregularly arranged, 10 – 35 µm in diameter. In transverse section, cells rectangular with length:width ratios varying from <1 to 2, and maximum diameters up to 25 µm. One pyrenoid per cell. Holotype DNA sequences: ITS GenBank PQ099646; tufA GenBank PQ099755; rbc L GenBank PQ 099533.

Etymology: The name honors Rachel Carson, renowned marine biologist, environmentalist, and author, and also reflects the holotype collection location, which was inside the Rachel Carson National Estuarine Research Reserve.
