Description
Plants epiphytic or saxicolous, erect and loosely branched, 3-6 cm tall, light rosy-red, attached by branched multicellular rhizoids issued from the basal cell, secondary multicellular rhizoids issued from occasional axial cells, encircling adjacent branches or other algae; branching lateral several cells distant from the apex at the distal ends of axis cells, appearing as short-celled dwarf shoots in early stages, later developing to reach the tips or even overtake the axes from which they were produced, when equal in length appearing as dichotomous; cells cylindrical, often becoming club-shaped especially in cells where branching occurs, but cells without branches generally only slightly wider in distal regions than at the proximal ends; axial cells 245-285 microns in diameter near the base, reaching 300-400 microns in diameter and 2.0-2.5 mm long in median positions, tapering to ultimate cells that are short-cylindrical or ovoid to spherical and 80-180 microns in diameter; tetrasporangia globose, to 390 microns in diameter, encircling distal ends of subapical to median cells, usually three borne on one-celled branches, associated with adjacent trichoblasts, but lacking involucral branches; gametangia unknown.
