theless Linneus' description is quite diagnostic of Retzius' scopulorum, certainly 

 more so than of canaliculata, as well it may be, judging from the material he 

 labeled in his herbarium; and certainly Acharius' procedure is difficult to waive 

 in favor of that of Fries,, who seems to have followed certain less discriminating 

 authors than Acharius.

Diagnosis: Thallus caespitose, compressed, linear, rigid, apothecia lateral, 

 spores straight, KOH+. 



Description: Thallus caespitose (max. alt. 20 cm.), rigid, cinerea-vires- 

 cent; cortex nitidous, striate, sublacunose; laciniae branched, compressed, linear 

 or sublinear, sulcate (max. width 6 mm.), apices attenuate. Apothecia marginal, 

 mostly subterminal, subpedicellate, concave, at length convex, marginate finally 

 immarginate (max. diam. 10 mm.), disk buff. Spores ellipsoid, straight, 4 5,6^5 



Observations: Though this species was included by Tuckerman on Nyl- 

 ander's authority (Synop. i860) as found in North America, no material has been 

 discovered in the herbaria examined. Nylander in 1870 included the allied 

 species cuspidata, and other authors have cited this species in reference to our 

 lichen flora. I believe, however, that the material from the Alaskan coastal 

 islands which is generally referred here will be found to represent Ramalina 

 subfarinacea Nyl., discussed below.
