North America, Europe, Asia.
Species ca. 20 (4 in the flora).
Brotherella is a problematic genus in which species are often polymorphic. Fragmentary material from other genera has been attributed to this genus, thus the systematics remain in flux. In northwestern North America there remain several specimens difficult to place, partly because material is sterile; these may well represent responses to extreme environments. The leaf margins are often recurved basally and plane distally; the acumina are curved; the supra-alar cells are shorter than the alar cells and in 1 or 2 rows; and the capsules are 0.5–2 mm.
