Observations: This species, attributed to North America in 1870, has 

 since been referred to as a member of our lichen flora by Delamare and Macoun. 

 Mr, Merrill was the first to question our material as cuspidata , thinking it more 

 nearly referable to the tropical Javanica Nyl.^ Though cuspidata may still be 

 found in our area, I believe, as already stated that our plants will be found to. 

 be the boreal subfarinacea. Our material has the positive reaction KOH+. Ny- 

 lander did not consider the often fistulous states of scopulorum and cuspidata a. 

 sufficient reason to include them in his "Stirps Ramalina pusilla," though he 

 placed them directly before it. Some authors have failed to detect other than 

 differing chemical reactions to separate these species. Acharius distinguished 

 them on account of the present species having smaller, slender, attenuate, black- 

 tipped laciniae; others claiming also a more tuberculate cortex for cuspidata. 

 They are no doubt separable by the Acharian diagnosis.

Description: Thallus caespitose (max, alt, 6 cm,), rigid, pale virescent; 

 cortex nitidous, tuberculate, fistulous; laciniae subsimple or branched, subterete 

 or subcompressed, apices generally multifid, sorediate, terete, attenuate, Apo- 

 thecia uncommon, concave at length convex and gibbous, marginate finally 

 immarginate, (max. diam. 4 mm.), disk buff. Spores ellipsoid, straight, ^^^M- 



Contingent phases: Unobserved. 



Substrata: Maritime rocks and tundra. [Cottonwood tree.] 

 Distribution: Alaska. 



Stations: Alaska: Atka Island; St. Paul's Island; St. George. 



Observations: This species, suggesting cuspidata more strongly than the 

 saxicolous states of farinacea, came to my notice through specimens collected by 

 Mr, F, B. McKechnie during July, 1911,^ As I have already said, I believe 



1 This is a subtropical species, and quite distinct.
