Mycologia 



26. i860 and Lich. Scand. 25. 1871. This variety has lately 

 been included by Mr. Merrill as a North American plant (Bryol. 

 1. c). I have seen one specimen that seems perhaps referable 

 to it, but since I have found no other material I hesitate to defi- 

 nitely accept this boreal variety. It was denned as follows : " thal- 

 lus erectus, brevis, subcaespitosus, rigidus, fusco-niger, nitidus, 

 sorediis destitittus, apicibus cnrvato-deflexis concoloribus." 

 " Norlandiae . . . Finmarkiae . . . Dovrensium." 



Material from St. Pauls island and Baffin land I have referred 

 to jubata, though in every respect they answer to this description, 

 except for their prostrate and slightly soraliate condition, — they 

 may however be better placed under chalybeiformis.
