Stypopodium

Stypopodium is a genus of thalloid brown alga in the family Dictyotaceae. Members of the genus are found in shallow tropical and subtropical seas around Africa, Pakistan, India, Japan, Indonesia, Australia, Micronesia, the Caribbean, Venezuela, and Brazil.

Characteristics
The thalli are usually erect but sometimes prostrate, growing to a length of about 35 cm. They are attached to the substrate by a rhizoidal holdfast and often form bushy clumps. The blades are membranous and either wedge shaped or divided into linear segments. The sporangia are densely scattered over the surface of the blade or occur in irregularly-shaped sori, forming four spores.
