Discussion:

Campylopus pilifer has 2–6 cell high lamellae on the back of the costa, long, hyaline, serrate, leaf hair-points, and enlarged, hyaline, thin-walled basal leaf cells. Although dorsal lamellae are always present on the costa, their height and number are variable. There are two distinct expressions of C. pilifer in Central America. One has plants with comal tufts at the ends of long erect stems bearing rigidly appressed leaves, and leaves with costal ventral hyalocysts smaller than the guide cells (e.g., Allen 14054, MO). The other lacks comal tufts, has leaves stiffly erect with incurved apices, and costal ventral hyalocysts distinctly larger than the guide cells (e.g., Allen 11281, MO). These two expressions most likely represent two species. The comal tufted form belongs to the subgroup of Campylopus characterized by small costal ventral hyalocysts and a comal tufted morphology.

Campylopus pilifer Brid., Musc. Recent. Suppl. 4: 72. 1819. Syntypes. Italy, in Insula Ischia, 1806; France, in saxosis sylvae prope Fontainebleau, 1807.

Plants small to medium, tufted, yellow-green to brownish yellow; stems variable in length, 1.0–6.5 cm long. Leaves crowded, erect-spreading when wet, appressed when dry, oblong-lanceolate, 3–6 mm long, subulate at apex and ending in a long, toothed, hyaline hair-point, to 1.9 mm long; margins subtubulose above, entire below, denticulate at apex; costa excurrent, dorsal surface with 2–6 cell high lamellae in the upper 2/3 of the leaf, in cross section with ventral hyalocysts either smaller than or distinctly larger than the guide cells, dorsal stereids well developed; upper cells oval to oblong, incrassate, not pitted, basal cells elongate-rectangular, bulging, hyaline, thin-walled; alar cells more or less quadrate in small weakly differentiated, reddish yellow groups. Setae 4–8 mm long, red-yellow, frequently aggregate from comal tufts, roughened above, smooth below; capsules erect, symmetric, cylindrical-ellipsoid, 1.0–1.5 mm long, scabrose at base, red-black; opercula short rostrate to long conic, 0.5–1.0 mm long. Calyptrae cucullate, 1.5–2.0 mm long, ciliate at base.
