504787C7ED7B1E74FCD5F051B2EF55EE.taxon	diagnosis	Diagnosis: Thallus light to dark red, up to 0.7 cm high, forming a turf on Stramonita rustica (Figure 4 A and B), with terete prostrate branches attached by brush-like holdfasts (Figure 4 C and D). Erect axes cylindrical at the base and flattened above 150 – 350 µm in width. Branches are rare, and when branches are occasionally present, they are irregularly arranged with one order of ramification (Figure 4 B – D).	en	Quiroz-González, Research Article Nataly, Ponce-Márquez, Maria Edith, Aguilar-Estrada, Luis Gabriel, Ruiz-Boijseauneau, Ivette (2024): A new species of marine algae from the Mexican Atlantic based on morphology and molecular data: Gelidium rodrigueziae sp. nov.

504787C7ED7B1E74FCD5F051B2EF55EE.taxon	description	Description: Plants a turf of purple-red thalli, with cylindrical prostrate axes attached to substratum with brush-like haptera (Figure 5 A) and erect linear to clavate axes, with irregular to smooth margins, cylindrical at base, 0.3 – 0.7 cm high and 150 – 350 µm in width (Figure 4 B – D). Axes in transverse section are ovoid, and elliptical. The shape of vegetative apices is acute (Figure 5 B). Cortex of 1 – 2 layers of rounded cells, 3.75 – 4.5 µm in diameter (Figure 5 C and D), outer cortical cells irregularly arranged in surface view. Medulla of 2 – 4 rows of circular or subcircular cells in transverse section, 10 – 12.5 μm in diameter, and with very large intercellular spaces. Internal rhizoidal filaments in the medulla (Figure 5 C and D).
