Type Information
Type locality: ledge north-east of St. George's Island, Bermuda (32°28.79600'N, 64°35.68833'W); (Schneider et al. 2020: 179, 180) Holotype (tetrasporophyte): C.W.Schneider/T.R.Popolizio 16-11-9 [BDA 1980]; 28 July 2016; from offshore ledge at 60 m depth; MICH; (Schneider et al. 2020: 179, 180, fig. 8) Notes: Isotype (tetrasporophyte): Herb. CWS [BDA1981] (fig. 9).

General Environment
This is a marine species.

Description
Plants firm, fleshy, compressed, light rosy-red, 10.5–12.8 cm tall, attached by cartilaginous, discoid holdfasts; main axes markedly compressed, 1–6 mm diam., percurrent, alternately to oppositely pinnately branched to 3-4 orders, with or without adventitious branches, branch length 3–54 mm, branch thickness 1.44–1.62 mm, smaller ultimate branches less compressed to terete, tapering to bases and to acute to apiculate apices; medulla of loosely arranged filaments, 3–12 µm diam., giving rise to the radially organised inner cortex of 3–4 layers of hyaline, regularly polygonal, thick-walled cells, 49–72 µm diam., 83–135 µm length; tapering to the outer 1–2 layered cortex of densely pigmented, elongate cells 4–11 µm diam., 12–25 µm length; tetrasporangia scattered, embedded in the outer cortex throughout except at branch apices and on older main axes, irregularly obovoid to ellipsoid in shape, zonately divided, 24–53 µm diam., 41–73 µm long; cystocarps embedded in apices of ultimate branches, carposporophytes 363-454 µm diam., surrounded by a fine network of anastomosing filaments; carposporangia obovate, 22–30 µm diam., 35–64 µm long; spermatangia unknown.

Habitat
On offshore reefs from 55–60 m depths

Similar Species
Differing from Tepoztequiella rhizoidea by its smaller size yet much wider and compressed axes, a lack of rhizoids issued from medullary filaments, and much larger tetrasporangia. It is also differentiated by its rbcL and COI-5P gene sequence
