Plants small, green to yellowish brown; capitula often small, not distinct radiate. Stem cortex in 1 layer, sometimes not well developed, hyaline cells lacking fibrils; central cylinder yellowish green.

Branch leaves ca. 1.1–1.4 mm × 0.3–0.4 mm, lanceolate, crowded and imbricate, spirally arranged when moist, not or only slightly undulate when dry, dentate and truncate at the apex; green cells in cross section triangular, exposed on the dorsal surface, slightly reaching the ventral surface; hyaline cells with large pores at the upper ends and a few small pores at the corners and along commissures on the dorsal surface, those from pendent branch leaves with numerous pores on the ventral surface.
