Newfoundland (Eckfeldt, Macoun, Arnold), Labrador {Eckfeldt, 

 Macoun), and Greenland {Stizenberger, Macoun) on the east 

 coast, and from Vancouver {Macoun) to Alaska {Cummings) on 

 the Pacific. In the interior it has been recorded from Great Bear 

 Lake (Leighton), and I have seen specimens from the Yukon, 

 Baffin land, Hudson bay and Hudson strait, Quebec and Keewa- 

 tin. It has also been reported from Mt. Orizaba, Mexico, by 

 Nylander. The Maine record seems in view of its range some- 

 what doubtful. 



Observations: This plant has been cited both as Alectoria 

 ochroleuca and Alectoria ochroleuca rigida (Vill.) Fr. The 

 names are, however, synonymous, the former having priority. I 

 have not seen a fertile example from our area, though fruited 

 European specimens are not uncommon. It is easily distinguished 

 by its erect growth, — suggesting slightly Cladonia rangiferina 

 (L.) Web. The name ochroleuca has so long stood, as in the 

 case of jubata and barbata, for a sectional rather than a specific 

 concept, that even in as recent a work as Miss Cummings' 

 " Lichens of Alaska " it is cited as well as the variety rigida, fol- 

 lowing the Tuckerman arrangement. Miss Cummings' key dis- 

 tinction limited the concolorous plants to ochroleuca, those " black- 

 ening at the tips " to the var. rigida. The original description of 

 ochroleuca, however, reads " apice furcatis, nigris," and it seems 

 that only the younger plants are concolorous.
