As I have above considered it expedient to place Ephemerum in 

 Funariacece, on the same principle Acaulon and its allies (Phascacea, 

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

 tellatum, which belong to WeisiacecB) must go into PottiacecB. The 

 near affinity of Pottia minutula to Phascum cuspidatum, &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 Pottiacea.
