Phyllariopsis brevipes is a species of large brown algae, found in the subtidal zone in the Mediterranean Sea. It is the type species of the genus.[2] Unlike other large brown macroalgae, it has a habitat requirement to grow on the living thalli of the crustose red alga Mesophyllum alternans.[3]
This is an uncommon species and is known from two locations in the Mediterranean Sea, the
The life history of this species has been elucidated in the laboratory. The sporophytes release zoospores which have eyespots. The zoospores germinate and develop into dioecious (distinct male and female) gametophytes, which each consist of an isodiametric (roughly spherical) group of cells which clump together. The gametophytes are monomorphic, that is, the male and female gametophytes are indistinguishable until they form gametangia (gamete-producing cells); no other member of the Laminariales has a similar arrangement, which is considered to be a primitive trait. Development then continues in a similar way to other members of the group, gametes are produced and the fertilised eggs develop into sporophytes, which only become fertile under short day-length conditions.[5]
