This is a marine species.
Thallus rosy-red, prostrate and spreading, attached to macroalgae and hard substrata by a fibrous holdfast and secondary rhizoidal fascicles issued from cortical cells on the contact surface; axes terete below, compressed distally, divided into segments by single-layered septa; mature segments distinctly barrel-shaped and markedly pinched at the septa, 440–1100 µm diam., shorter than broad distally, about as long as broad in lowermost segments, increasing in breadth towards the apex of axes but abruptly decreasing in length and width in the final few distal segments; branches alternate and opposite, formed at or just above septa; septal cells colorless, polygonal, reticulate, 39–72 µm broad and 69–81 µm long; cortex 2-layered, the larger (inner) cells forming a complete layer of rounded ellipsoidal to polygonal cells, 30–55 diam. and 42-125 µm long in mature segments, cutting off an incomplete layer of smaller subspherical to ovoid, cortical cells outwardly, 5–15 µm in longest dimension; hairs deciduous, when seen found distally, originating from small, outer cortical cells; inner cortical cells of distal segments issuing longitudinal, descending filaments, 4.0–10.5 µm diam. that produce obovoid to spherical gland cells 8.5–11.0 µm diam. in the interior cavity; sporangia scattered under the cortex of internodal segments, tetrahedrally divided, spherical, larger forms 55–75 µm diam.; cystocarps broadly ovoid and ostiolate at maturity, 740 diam. and 620 µm tall, carposporangia obpyriform to 93 µm long; spermatangia unknown.
epiphytic, 1-36 m depths
