Plants 3–4 cm, in loose tufts, brown proximally, green distally. Stems sometimes branched. Leaves moderately crowded, somewhat contorted when dry, lingulate, 2–4 × 1–1.4 mm; margins plane or recurved proximally, entire or nearly so, sometimes with blunt teeth; apex obtuse to rounded; costa ending before apex. Specialized asexual reproduction absent. Sexual condition autoicous, sometimes apparently dioicous. Seta bright red, 1.5–4 cm, flexuose, slender. Capsule ± ovoid, 1.5–2.5 mm including hypophysis; hypophysis concolorous or slightly darker than urn, as long as urn; columella included; operculum deciduous, convex, nearly flat when dry, apex bluntly and obliquely umbonate to short-rostrate; peristome inserted somewhat below mouth, prostome present as small, brownish, papillose fragments; exostome teeth 16, not split, erect when dry, deep yellow or orange-yellow, broadly lanceolate. Spores 26–45 µm, smooth.

Discussion

Tayloria lingulata is distinguished by its tongue-shaped leaves. Also, the setae are relatively slender. The 16 exostome teeth are separate and erect, and the short, broad urn is about as long as the hypophysis.
