216. Ramalina pusilla geniculata (Hook. & Taylor) Tuck. 



Ramalina geniculata Hooker & Taylor, Lond. Jour. Bot. 3 : 655. 1844. 

 Ramalina pusilla geniculata Tuckerman, Syn. N. A. L. i : 26. 1882. 



Fraser Reach, Princess Royal Island, British Columbia (Coville and 

 Kearney, 304) ; St. Michael (Setchell) ; St. Matthew Island (Tre- 

 lease, 1191, 1257). All the specimens are sterile. A specimen col- 

 lected by Dr. Bean and determined by Rothrock was referred here. 

 Nylander, in his revision of Rothrock's list, places the specimen under 

 the species R. minuscula Nyl., which Nylander records as also occur- 

 ring at Port Clarence and on St. Lawrence Island. 



No. 304 is very finely divided, many of the branches ending in capi- 

 tate soredia. It resembles specimens in the Tuckerman collection from 

 Anticosti and the Gaspe coast. The species as represented in the 

 Tuckerman Herbarium shows great variation in the fineness of the 

 division of the terminal segments and in the regularity of branching as 

 well as in the presence of soredia. 



Additional Alaska species are : R. cuspidata^ collected by J. M. 

 Macounon St. Paul Island; and 7?. calicaris farinacea Fr. collected 

 by Dr. Bean on Little Koniuji Island. Shumagin group. 



ADDITIONAL GENERA. 



Five genera of which there are no specimens in the Harriman col- 

 lection have been recorded as occurring in Alaska. A list of these, 

 with the recorded species, is appended. 



Varicellaria microsticta Nyl., reported by Nylander from Port 

 Clarence; Sphinctrina turbinata (Pers.) Nyl., from the same locality 

 as the preceding; Pycnothalia cladinoides, collected by William 

 Palmer on St. Paul Island, determined by W. W. Calkins ; Urceo-
