Scientific Description
Habit and structure. Thallus encrusting to warty or fruticose, up to 1000 μm thick, monomerous in construction. Medulla multilayered, plumose; cells fusing laterally. Cortex multilayered; cells 9–20 μm long, 8–15 μm diam. Cortical filaments ending in an intercalary initial cell that subtends a rounded epithallial cell 2–5 μm long, 2.5–4.0 μm diam. Intercalary initials generally similar in size to the cortical cells they produce. Trichocytes scattered throughout the upper cortex, not evident deeper in the cortex, usually single and multicelled, not generally grouped; uppermost cell of trichocyte 33–45 μm long, 20–40 μm diam.
Reproduction. Carposporangial conceptacles raised, conical, with an extended ostiole, 400–490 μm outside diam. Tetrasporangial conceptacles raised, conical, with a distinct extended ostiole (visible to the naked eye), 1000–1500 μm outside diam.
Distribution. Widespread in warmer seas.
Habitat. Epilithic in the subtidal.
