Splachnaceae currently resides in the order Splachnales (M. Fleisch.)
Ochyra; which is further nestled within the class Bryopsida.
It comprises 6 genera and approximately 73 species.
The type genus is Splachnum Hedw.

Three subfamilies have been named within the Splachnaceae.

Splachnoideae (Aplodon, Splachnum,Tetraplodon) can be distinguished by their highly differentiated and often inflated hypophysis.
All species are coprophilous and entomophilous excluding T. paradoxus, which is only coprophilous.
Genera are distinguished by their peristome teeth.

Voitioideae (Voitia) is characterized by the absence of a differentiated line of dehiscence on the sporangium (cleistocarpy).
Spore dispersal is only achieved following the decay of the sporangial wall.
Species in this subfamily are coprophilous but not entomophilous.

Taylorioideae (Moseniella, Tayloria) is the most polymorphic subfamily, with species that inhabit many different niches.
