Of the relation of our Lichen Flora to that of Asia and Japan, 

 I have little information. The following, originally published as 

 American, have been found in the regions indicated. 



Cetraria Ricbardsonii Siberia. 



C. cbrysantlia Japan. 



Umbilicaria rugifera ...... Siberia. 



U. Mublenbergii Siberia. 



U. Pennsylvanica Asia ; Japan. 



Collema leptaleum .... Japan. 



Alectoria Fremontii, Cetraria Oakesiana, Thelotrema subtile, and 

 Conotrema iirceolatum, occur in Europe; Usnea cavernosa, in S. 

 America and India ; U. angulata, in S. America and New Zealand ; 

 Eamalina reticulata, in New Zealand; Pannaria leucosticta, in New 

 Zealand ; and R. tenuis, is cosmopolitan. These lists might doubtless 

 be extended.
