Besides the Favolus and Fomes above mentioned, the collection of

dried agaric, also alcoholic material of two Agarieini and a small

LICHENES. 
Br W. G. FARLOW. 
Judged by the collections of previous expeditions as well as those of 
Messrs. Snodgrass & Heller, the lichen flora of the Galapagos Islands 
must be striking in appearance and abundant. Naturally the collections 
include principally the larger and more showy species of foliose and 
fruticulose habit, which are in most cases identical with species found 
along the Pacitie Coast of America from California to Chili. Hooker 
(3), 164, records three lichens collected by Darwin on James Island; 
Andersson secured nine species from James and Chatham Islands, and 
Baur six from Charles, Albemarle, Hood, and Chatham Islands. The 
lichens collected by Hill on the Hassler Expedition were determined by 
Tuckerman and included three new species, Lecanora glaucovirens, 
Rinodina mamillana, and Pertusaria albinea, the second species having 
been found previously in Hawaii. Willey in his Synopsis of the Genus 
Arthonia, 1890, described an Arthonia nivea from the Galapagos Islands 
(collected by Hill), and reported A. platyspeilea Nyl., as well as a 
third unnamed species. The last was sent to Nylander, but I am unable 
to ascertain whether it was ever named by him. Apparently a con- 
siderable number of lichens were collected by the Hassler Expedition, 
but no list of them was ever made so far as I am aware, and as the speci- 
mens are scattered through the Tuckerman Herbarium no enumeration 
could be made without a long search. In the following catalogue refer- 
ence is made to such of these specimens as have come under my notice.
