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.
