For this last species, long current under the name of F. Muh- 

 lenbergii, Schwcegr., Schiinper (Synop. 1. c.) adopts F. calcarea, 

 Wahl.) as tbe prior name, alleging that F. Muhlenbergii, found- 

 ed on Pennsylvania specimens sent to Hedwig, differs in many 

 particulars (not stated) from F. calcarea, Wahl. 



Of F. Muhlenbergii, as understood by Schimper, we have seen 

 no specimens.
