Stems to 20 mm, central strand absent. Leaves oblong to elliptic, 4--6 mm, apices broadly acute to rounded, mucronate to cuspidate, margins recurved below mid-leaf; costa excurrent or subpercurrent, narrow; laminal cells 10--20 µm,; basal cells rectangular, 50--120 µm, smooth; basal marginal cells weakly differentiated below, in 4--8 rows, elongate, smooth. Specialized asexual reproduction absent. Seta 4--14 mm, yellow to yellowish brown. Capsule cylindric, 2--3 mm, smooth, constricted below mouth, yellowish brown, exothecial cells rectangular, 50--120 µm; peristome single, yellowish red to hyaline, 16 teeth, lanceolate, to 0.3 mm high, papillose, erect; operculum 1--1.5 mm. Calyptra 3--7 mm, fringed at base, smooth or rarely papillose at apex. Spores 30--40 µm, plicae and pitted, brownish yellow.

Encalypta ciliata is of the most variable species in leaf shape, apex development, and costae length. A combination of excurrent costa, smooth capsule wall, and single peristome will serve to separate E. ciliata specimens.
