As I have above considered it expedient to place EpJiemerum in 

 Funariacece, on the same principle Acaulon and its allies {Phascacece, 

 C. Muell., excluding Ph. crispum, multicapsulare, polycarpum and roS' 

 tellatum, vs^hich belong to Weisiacece) must go into Pottiaceee. The 

 near affinity of Pottia minutula to Phascum cuspidatmn, &c. is too 

 obvious to require proof; and as there are some Phasca (e. g. Ph. 

 bryoides) which have an easily separable, not to say deciduous lid, there 

 would seem to be no character, either natural or artificial, sufficiently 

 constant to justify the separation of the latter from Pottiaceee.
