Plants often blackish or dark brown, sometimes olive green. Leaves secund to often deciduous, lanceolate-subulate, obtuse, costae filling subula; margins denticulate at apex, entire below, leaf cells (1–)3:1, quadrate to rectangular-elliptic; perichaetial leaves abruptly subulate. Seta 3–13 mm, flexuose. Capsule ovate to narrowly pyriform, peristome of 16, lanceolate teeth; columella not developed. Spores 13–20 µm.
Habitat: Moist or dripping acidic rock faces, most common in montane/alpine habitats
Elevation: low to high elevations (0-3000 m)

Discussion
Blindia acuta forms soft blackish mats on acidic rocks in moist arctic, alpine, and montane habitats. The well-developed alar cells, smooth leaf cells, subulate leaves, and short-ovate, smooth capsules with well-developed, smooth peristome teeth are distinguishing features. Seligeria species are smaller and occur on calcareous rocks.
