Description
Species Description - Plants yellow-green to brown. Stems rarely branched, up to 12 mm high. Propagula often present, axillary, stalked, consisting of 3-50 cells, 80-300 µm long, green to brown, obovoid, clavate, spindle-shaped, ellipsoidal, or globose, raspberry-like or armed with 1-several short-pointed branches. Leaves crowded to ± distant, nearly uniform in size, when dry erect-incurved, often infolded above, occasionally catenulate, w h e n moist erect-spreading, straight or incurved, 0.5-1.8 mm long, ovate to lingulate, occasionally lanceolate or long-triangular, grooved at the costa, rounded to bluntly acute, apiculate by a single pellucid cell, rarely muticous, the base scarcely differentiated to much broadened and square, rectangular, or oval; margins plane to slightly recurved at midleaf, entire; costa percurrent or ending 1-4 cells below an apiculate apex or occasionally excurrent as a sharp mucro, covered dorsally by ± rectangular cells generally with both ends projecting as papillae (or occasionally with only 1 end projecting or smooth), with ventral stereids none or poorly represented; upper cells quadrate, 7-9(-10) µm wide, with 4—8 low, mostly hollow papillae per cell; basal cells 8-12 µm wide, 2-5:1, rectangular, those in 1-4 marginal rows shortrectangular. Perichaetial leaves 0.8-2.5(-3) mm long, ovate with cells completely elongate or lanceolate with elongate cells only in the lower third. Setae 7-13 mm long, red-brown; capsules 0.8-1.8 mm long, red-brown, ellipsoidal to ovoid, occasionally curved; operculum 0.8-1.7 mm long, short- to long-conic; peristome 0.7-1.7 mm long, the slender, densely spiculose divisions ± fused in pairs, only slightly to strongly twisted in 0.25-3 turns, with many articulations, red to orange. Spores (8—)9—12 µm, smooth to weakly papillose.

The variation is treated more fully by Zander (1979a). The roughness at the back of the costa caused by papilla-like projections at both ends of cells distinguishes this from other Mexican species of Barbula. T w o intergrading extremes may be recognized.
