Description
Plants saxicolous, lubricious, purplish-red, to 4.5 cm tall, attached by small, discoid holdfasts, giving rise to one or more erect, branched, curved axes, soon becoming secondarily attached by adventitious rhizoidal pads issued from decumbent axes and branches, spreading and becoming entangled; axes distinctly flattened, to 1 mm wide and 300 µm thick in lower portions, irregularly to alternately branched, often secund on recurved branches, tapering to acute apices +/-200 µm in diameter and less markedly to bases; medulla of loosely entangled elongate filaments, 5-10 µm in diameter, giving rise to the radially organized inner cortex with anastomosing, elongate stellate cells, and an outer cortex of 1-2 globose to ovoid cells bearing ultimate paired narrowly elongate to obclaviform cells, 2-3 µm in diameter, 4-10 µm long, round in surface view; spermatangia developing from outer cortical cells, formed in slightly raised patches, spherical spermatia 1-2 µm in diameter; tetrasporangia and carposporophytes unknown.
