Andreaea is a genus of rock mosses with about 45 species.They are small delicate acrocarpous mosses (meaning that the capsules are formed at the tips of vertical branches) that form dark brown or reddish cushions on wet siliceous rocks in mountainous areas. The capsule lacks the peristome teeth and operculum of other mosses and opens by splitting along 4 vertical slits the four valves remaining joined at the base and apex.
