Stems stiff, slenderly julaceous, sterile and young material filiform, central strand distinct. Leaves proximally minute, 0.5-1 mm, scalelike, becoming larger and ovate-lanceolate distally; apex obtuse, subcucullate to acuminate-subulate in distal leaves; lamina 1-stratose; costa strong, less than a quarter of the leaf width, in section hydroids absent; median laminal cells (25-)30-60 × 8-15 µm, thinner, longer and narrower at the margin and forming a smooth, non-erose, indistinct border parallel to the margin. Perigonium a dark knob or apical rosette wider than the stem, formed by largest leaves, incurved-tubulose, to twice the length of the cauline leaves, abruptly narrowed into a tubulose acumination that can be longer than the leaf body. Perichaetium a large apical tuft, the leaves larger than stem leaves, to 1.5 mm, long-lanceolate and tubulose, acuminate from a broad, sheathing base, in most distal leaves rapidly or fairly rapidly narrowed into a blunt subula. Seta 4-10(-12) mm. Capsule exserted, brown, 0.6-1 mm, without stomates; peristome entire, perforate or divided nearly 1/2 distally, more or less vertically striolate to almost smooth basally, yellow and finely papillose to smooth distally; operculum to 0.4 mm.
