Hypnea musciformis is a seaweed that forms clumps or masses of loosely intertwined, cylindrical branches, 4-8 inches cm tall, 0.1-0.2 inches in diameter, that become progressively more slender towards the tips. It is firm, cartilaginous, and highly branched. Branching is variable and irregular, often tendril-like and twisted around axes of other algae. The ends of many axes and branches are flattened with broad hooks. Holdfasts are small, inconspicuous, or lacking. It is usually red, but can be yellowish brown in high light environments or in nutrient poor waters. This species is easily distinguished from other native Hypnea species by the presence of flattened, broad hooks at the tips of the branches. It is often found as an epiphyte on other reef algae.
