Dicranidae
The Dicranidae are a widespread and diverse subclass of mosses in class Bryopsida, with many species of dry or disturbed areas. They are distinguished by their spores; the peristome teeth are haplolepideous with a 4:2:3 formula, and an exostome is absent. Dicranidae are an acrocarpous class of moss. Their foilage is unbranched and erect, often forming a mounded colony. The archegonia (female sex organ) and hence capsules are borne at the tips of the erect stems. References
