    Species Description - Plants 11 mm or more long, branched from older portions, tufted and often forming extensive mats. Leaves oblong, up to 2.7 mm long, obtuse to broadly acute, cuspidate, often ± undulate; margins unbordered, ± evenly serrulate, often crenulate-serrulate on the ventral and dorsal laminae; costa strong, generally extending into the cuspidate tip; dorsal lamina truncate-rounded and ± undulate below; vaginant laminae ± unequal, about 2/3 the leaf length; cells irregularly hexagonal, 8-11 µm, larger and clearer along the costa, the marginal ones frequently paler, smooth and bulging in upper parts of leaves, conspicuously mammillose in the vaginant laminae. Rhizautoicous (antheridia in short bud-like branches at bases of stems and perichaetia on short, basal, axillary branches). Setae up to 17 mm long; capsules inclined and ± curved, up to 1.9 mm long; opercula long-rostrate; peristome teeth deeply divided, finely papillose below, articulate and spirally striolate above. Spores 13-18 µm, finely papillose. Calyptrae cucullate.

    The rather robust plants are best recognized by evenly serrulate leaf margins, stout costae ending in cuspidate leaf apices, conspicuously mammillose cells of the vaginant laminae, and basal sporophytes

  • Distribution
