Description
Plants growing in small cushions. Leaves non crisped, undulate to somewhat curved, (2.0–)2.5–3.15 × 0.4–0.6 mm; leaf margin crenulate-serrate, more strongly towards apex, with protruding papillae. Costa dorsal cells papillose. Lamina cells with 1(–2) single or ramified papillae. Differentiated basal marginal cells in more than five rows. Perichaetial leaves differentiated, with sheathing base, abruptly narrowed towards lamina and with blunt to obtuse apex. Vaginula naked, 0.4–0.7 mm long. Calyptra naked with dark beak, 1.5–1.9 mm long. Seta (2.75–)4.0– 5.7 mm long. Capsule fusiform when dry and full of spores, cylindrical when dry and empty, somewhat wider below its middle, 1.35–2.2 mm long including neck; ribs moderately marked, concolorous with rest of exothecium. Stomata scattered from urn base and neck to near capsule mouth. Exothecial bands thin, scarcely differentiated, formed by 2–3 cell rows with walls not strongly thickened. Operculum plane-convex, with broad reddish basal rim. Peristome double. Exostome of 8 pairs of teeth with tendency to split, but usually remaining joined at tips, brown-orange, sometimes paler, 230–325(–356) µm long; external side (outer peristome layer = OPL) ornamented in basal section by reticule with tall papillae, in upper ⅓–¼ with longitudinal crests and aligned papillae, sometimes uniformly papillose; inner side (primary peristome layer = PPL) with scattered tall papillae, becoming denser at tips and sometimes longitudinally aligned at base. Endostome of 8 segments, occasionally with remains of incomplete intermediates, brown-orange, sometimes paler, filiform and fragile, sometimes wider and more persistent; uni-biseriate at base, uniseriate above, almost as long as teeth; external side (PPL) smooth in basal ¾, in the upper ⅓ smooth but ornamented with clusters of high papillae, with appearance of tufts, which can protrude laterally, much less frequently with lines; inner surface (inner peristome layer = IPL) with base ornamented by low reticulum with coralloid aspect or by papillae, in upper parts smooth and with papillae in clusters as in PPL, rarely more or less homogeneously papillose with these clusters not or hardly developed; trabeculae differentiated. Spores finely papillose, 20–30 µm in diameter.
