Description
Thallus rosy-red, spreading and erect to 3 cm tall, axes terete or slightly compressed, axes attached to other branches by secondary rhizoidal fascicles issued from cortical cells on the contact surface, at times forming mats interconnected with other algae; axes divided into segments by single-layered septa; mature segments shallowly pinched at the septa or not at all in distal segments, at times more so in some lower mature axes; segments 250-850 µm diam. and 250–700 µm in length, decreasing distally; branches alternate to secund and irregular, formed at or in between septa, at times with more than one branch arising from the same segment; septal cells lightly pigmented, forming a complete layer of irregularly polygonal cells, 25-50 µm diam. and 30-85 long; cortex 2-layered, the larger (inner) cells forming a complete layer of ellipsoidal to irregularly polygonal and ovoidal cells, 15–50 diam. and 24-175 µm long in mature segments, the long cells paralleling plant axes, cutting off an incomplete layer of smaller subspherical, reniform, pyriform to ovoid, cortical cells outwardly, 5–16 µm in longest dimension; inner cortical cells of distal segments issuing longitudinal, descending filaments 7–12 µm diam. that produce obovoid to spherical gland cells, 9-17 µm diam. in the interior cavity; sporangia scattered under the cortex of internodal segments, tetrahedrally divided, obovoid to spherical, larger forms 80-110 µm diam.; cystocarps urceolate and ostiolate at maturity, 520–600 µm diam., 640–760 µm tall, occasionally clustered, carposporangia obpyriform to 100 µm long; spermatangia unknown.
