General Description

One to several flattened stems (stipes) arising from holdfast. Branching in a tree-like (arborescent) pattern mostly on one plane. Secondary branches are ribbon-like with thickened vein-like midlines. Numerous secondary branches usually distributed evenly in groups of two or more. Lateral blades have fan-shaped (flabellate) ends. Obvious pale circular lumps (conceptacles) on blade surface when reproductive. Pink to dull red. Up to 23 cm long (thallus).
