Leaves erect and strongly curled when dry, erect-spreading when moist, 2-3 mm long; costa ending near the apex; upper cells rounded-quadrate or elliptic, unipappilose on both sides.

Mosses in this genus are similar to those of Orthotrichum but have leaves bordered at the base by one to several rows of pale, short cells with thickened cross walls. The leaves of Orthotrichum spp. are not bordered at the base.
