Phaeophycae

Phaeophycae

a class of algae, comprising the brown algae. The class is usually raised to the status of a division called Phaeophyta. They are mostly marine and their green pigment is masked by fucoxanthin, a yellow pigment. Some members of the group are the largest algae known and may reach several metres in length, for example, Laminaria, the kelp.
