Characteristics

Plants medium-sized, red-brown or sometimes pale yellow-green to yellow-brown, sometimes hoary distally. Stems with stoloniform-flagelliform branches absent. Leaves ± closely appressed-imbricate, not plicate, 0.7-1.5 mm; margins recurved to just beyond mid leaf, plane in acumen, entire to subdenticulate at apex; apex somewhat to strongly secund and spreading when dry, erect-to wide-spreading when moist, acute, ± gradually acuminate, or piliferous, opaque to translucent white, flat, papillose proximally, smooth distally; alar cells ± isodiametric, smooth to mostly 1-papillose distally, walls even, thinner than laminal cells, region concolorous, excavate; mid basal laminal cells short-rectangular, becoming long-rectangular, 1-papillose, appearing smooth, papillae not in rows, walls thick, moderately porose, region concolorous or slightly more strongly yellow to orange-yellow at insertion or to 1/5 leaf length; medial cells 1 (or 2)-papillose over lumen, papillae simple, stoutly tuberculate, walls thick, coarsely and irregularly porose; distal cells similar to and concolorous with medial cells, smooth; apical cells hyaline. Sexual condition autoicous; perichaetial leaves similar to vegetative leaves or larger, to 3 mm, margins entire. Vaginula with paraphyses many, smooth, not extending onto developing calyptra. Seta pale yellow, (4.5-)5-9(-10) mm, slender, extending beyond perichaetial leaves. Capsule exserted, yellow-to red-brown, obpyriform to turbinate when dry, ovoid-pyriform when moist, 1-1.3 mm, longitudinally sulcate-ribbed when dry, smooth when moist, mouth wide; stomata phaneroporic; operculum conic, stoutly, bluntly, and obliquely short-rostrate. Calyptra cucullate, 2.5-3 mm, covering to below mid capsule, naked. Spores 24-28 µm, finely to coarsely vermiculate-papillose.
