Rhacocarpus purpurascens

Mats on rock, bronze to glaucous green toward the tips. Stems (20–) 60–80 (–100) mm long, subpinnately branched, red-brown, without rhizoids. Leaves spreading when moist, appressed with reflexed tips when dry, stem leaves differing from branch leaves; cells in apical half linear-rhomboidal or fusiform, 12–75 μm long, 6–12 μm wide, densely granulate; basal cells longer but not strongly differentiated, 60–100 μm long, 8–12 μm wide, densely granulate; alar cells quadrate to short-rectangular, reddish, smooth, forming an auriculate group. Stem leaves ovate to oblong, acuminate apex, 1.5–3 mm long, (0.6–) 0.8–1 mm wide, concave; base oblong-panduriform; apex acute to acuminate, with a golden or castaneous hair-point; margins denticulate near base of hairpoint, otherwise entire, strongly inrolled below hair-point, recurved near base, with c. 3–4 rows of narrower, smooth, pigmented cells forming a distinct reddish border from base to mid-leaf or nearly to base of hair-point. Branch leaves smaller, mostly c. 2/3 length and width of stem leaves, less strongly decurrent. Setae 6–20 mm long, yellow- or red-brown, smooth. Capsules ellipsoid or broadly obovoid, nearly globose after dehiscence, erect, 2–2.5 mm long. Operculum obliquely-rostrate from conic base, 2–2.5 mm long.
