Thalli are erect, to 25 cm high and pinnately branched up to 5 orders. A percurrent main axis is lacking.The holdfast is densely rhizoidal. Axes are corticated from close to the apices, with corticating filaments arising from the periaxial cells 5 to 10 cells proximal to the apex. Near the base the axes attain a width of 1.5 mm. Each axial cell bears a single lateral in a distichous-alternate pattern. Determinate branchlets are ecorticate, straight, 12-17 cells long and pinnately branched. Spinelike cells are absent. Indeterminate branchlets are formed irregularly and repeat the branching pattern of the main axes. Tetrahedrally divided tetrasporangia (40-52 μm in diameter) are borne laterally or terminally on the ultimate branchlets. Gametophytic plants were not observed (Ref. 82093).
Euptilota articulata has only been collected once in situ, at a depth of 35 m in southern Natal. The specimen in the Norris Herbarium (UN) was collected from the drift (Ref. 82093).
