Plants delicate to coarse, in fern-like tufts, dark, to dull purple. Erect branches arise randomly from prostrate fibrous axes that produce random haptera ventrally at forks. Branching of erect axes sparse and alternate below and distichous and spreading above. Older erect axes determinate, stiff, denuded, and with flexible, pinnate, featherlike, incurved branchlets above. Main axes with 6-7 pericentral cells and 5-7 layers of cortical cells. Branchlets ecorticate and having 5 pericentral cells, with the last 2-5 segments uniseriate. Tetrasporangia tetrahedrally divided and within 2 rows of swollen stichidia that are short-stalked and partially corticated. Cystocarps ovoid, terminal, and either solitary or in pairs.
