Sphagnopsida is a class of mosses that includes a single subclass Sphagnidae, with two orders. It is estimated it originated about 465 million years ago, along with Takakia.[1] The order Sphagnales contains four living genera: Ambuchanania, Eosphagnum, and Flatbergium, which counts four species in total, and Sphagnum which contains the rest of the species. The extinct Protosphagnales contains a single fossil species.
