Plants to 1-4 cm long or intertwined to form a thin mat over the substratum, generally showing rhizomatous axes bearing erect pinnate branches 0.8-5.0 mm tall, with descending rhizoids opposite these. The main erect axes 20-25 µ diameter, the cells 2-5 diameters long, subcylindrical or somewhat clavate, bearing the branchlets at the forward end. Branchlets opposite in pairs, 10-15 µ diameter, sometimes reduced or absent sometimes alternating 90° in position in succeeding nodes. On well developed or erect branches regularly distichously pinnate and plumose, the pinnae somewhat ascending, about 60-210 µ long, often regularly again pinnate on the upper side only, or secund, varying greatly from the plumose to very irregular forms on the same plant. Sporangia tetrahedral, spherical or somewhat ovoid, 30-35 µ diameter.
