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. 1 : 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 Rotlirock’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 R. calicarisfarinacea 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; Sphinctriiza 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 - 
laria scruposa (L.) Ach., collected by Dr. Bean, no special locality 
being recorded ; Gyalecta cotzvarians Nyl., reported for Port Clarence 
by Nylander; Gyalecta rhexoblephara (Nyl.) Tuck., collected by 
Wright on the islands of Bering Sea; and Evernia thamnodes (Flot.)
