Stems prostrate, irregularly branched, the branches tumid to ± flattened even on the s a m e plants. Leaves ± imbricate to erect-spreading, lanceolate-ovate to ovate, acuminate, gradually tapered, (1.3-) 1.9-2.4 mm long; margins plane, sermlate in the upper half; costa short and double; cells linear, not appreciably shorter at the apex; alar cells numerous, quadrate to short-rectangular, ± abmptly differentiated from those above, seldom reaching the costa. Autoicous. Setae yellowish, 1-1.5 cm long; capsules 3-4 mm long; annulus none; operculum conic-rostrate; exostome teeth lanceolate, yellow or orange, striate below, faintly papillose above; endostome usually papillose and often coarsely so.

This somewhat confusing species differs from E. abbreviatus in having a less tumid habit, leaves gradually acuminate, setae somewhat longer, and endostome usually papillose. The fact that the quadrate alar cells only rarely reach the costa and the leaves are, by comparison, rather broad makes possible a separation from E. serrulatus.
