Orthotrichum rufulum Mitt., J. Linn. Soc., Bot. 12:191, 1869. [Original material: Near Valdivia, Chile, coll. Lechler n. 527 part.]

Orthotrichum brevicolle Mitt., J. Linn. Soc., Bot. 12:192, 1869. [Original material: Near Valdivia, Chile, coll. Lechler n. 527 part.]

Orthotrichum chilense Mitt., J. Linn. Soc., Bot. 12:193, 1869. [Original material: Near Valdivia, Chile, coll. Lechler n. 527 part.]

Plants light green, with stems in tufts to 5 mm high. Leaves ca. 2 mm long, 0.5 mm wide, linear-lanceolate from an obtrapezoidal base; margins entire; costa subpercurrent; lower margins with 5–10 rows of cells that are 12 μm wide and 12–15 μm long, with transverse walls more thickened; cells of upper lamina rounded to elliptical with very thick walls, 8 μm wide, usually 7–12 μm long, lumens 5 μm wide, in distinct longitudinal rows, slightly papillose; inner basal cells 7 μm wide, 25–40 μm long, smooth. Autoicous. Perichaetial leaves to 3 mm long. Setae ca. 3 mm long, yellow. Capsule urn ca. 1.2 mm long, usually contracted under mouth when dry; endostome segments 8, slender, weakly papillose. Spores 19–26 μm in diameter. Calyptra hairy.

MAS AFUERA: Camp Correspondencia, 1150 m, Sk. M124 part (S).

The species occurs in New Zealand, Juan Fernandez, central Chile, and adjacent Argentina. Malta (1929) described a variety patagonica with spores 26–37 μm in diameter, but otherwise the species seems totally distinct from the preceding.
