Description
Plants light to dark rosy-red and erect to 15 cm tall, composed of broadly ligulate, pseudodichotomously to irregularly branched blades; single, or occasionally a few, proximally tapering blades on simple to branched stipes to 1 cm long, arising from small discoidal holdfasts or eroded axes, the stipes at times extending into proximal portions of the blades as short midribs; blades increasing in breadth distally, to 3 cm wide and 80-150 µm thick below branching nodes in upper portions, the margins entire, often undulate, but appearing crenate distally due to an abundance of incipient branching; medulla comprised of a loosely woven, mucilaginous matrix with fine intertwining, elongate filaments, 1.5-3.5 µm diam., some running from one cortex to another, all interspersed with coarse, darkly staining filaments generally 4-8 µm diam. directly connected to large densely staining, stellate ganglial cells; medulla giving rise to a 2-(3-) layered cortex composed of cells 4.5-9.0 µm diam., transversely elongate in transverse section, irregularly rounded angular in surface view; gametangia and tetrasporangia unknown.
