Plants to c. 3.5 cm tall, yellowish green to green; shoots uniformly foliate. Leaves appressed to erecto-patent when dry, slightly curved and homomallous when moist, narrowly ovate-lanceolate, 3.8-4.6 mm long, 0.6-0.7 mm wide, ending in a short hyaline point (this occasionally absent or slightly longer); costa occupying c. 50-75% of the leaf width, abaxially with many low ribs, toothed in the upper half, adaxially with hyalocysts throughout. Alar patches well developed in most leaves, single-layered; cells hyaline, thin-walled, inflated; basal hyaline cells occupying the entire laminal width directly above the alar patches. Upper laminal cells rounded-rhomboidal to ±quadrate, isodiametric or oblong, 12-25 x 6-18 µm, not pitted; transition cells slightly larger, many cells ±rectangular. Gametoecia and sporogones unknown.
