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.
