﻿Howe: Genus Teloschistes in North America 583 



Substrata: Shrubs. 



Geographical distribution: Not uncommon in the Transi- 

 tion Zone from Santa Cruz Island south to Lower California. 



Observations: This well marked species was added to our 

 lichen flora in 1910 when I recorded specimens collected by- 



Miss Blanche Trask in 1892.* It had been secured, however, 

 in Lower California at an earlier date and distributed in Miss 

 Cummings's Exsiccati. 



ExsiccATi: Cummings, No. Amer. Lichens 154.
