Stems to 10 mm, central strand weakly differentiated, cells very thin-walled. Leaves oblong to lingulate or ligulate, 1.5–3 mm, apices obtuse to broadly acute, hair-pointed, margins plane, weakly bordered; costa excurrent, awns shorter than leaf lamina, smooth, narrow; laminal cells 12–18 µm; basal-cells rectangular, 30–70 µm, smooth; basal marginal cells weakly differentiated, in 12–18 rows, longer than laminal cells. Specialized asexual reproduction absent. Seta 3–8 mm, dark red. Capsule short-cylindric, 1–2 mm, weakly striate to ribbed, gymnostomous, yellowish-brown, exothecial cells rectangular to linear, walls thickened; peristome absent; operculum 0.5 mm. Calyptra 2–4 mm, lacerate at base, smooth. Spores 26–35 µm, warty, brown.

Discussion

Encalypta spathulata is very similar to E. rhaptocarpa but differs in the fringed calyptra base and weakly striate, eperistomate capsule. The gymnostomous capsules and long awn will separate E. spathulata from other species of the genus.
