Primary thallus of leafy, elongate or medium sized, numerous and 

 often densely imbricate squamules which may pass into an effuse, 

 powdery crust; squamules more or less lobed, with crenate or lacini- 

 ate margins, flat or concave, more or less ascendant; color pale to 

 dull sage-green or varying to whitish or brownish green, or olivaceous ; 

 beneath white. 



Podetia rising from surface of squamules, simple or sparingly 

 short-branched in the upper portion, small to medium size, slender 

 or becoming rather stout, terete; apically pointed and thread-like, 

 or coarser, thicker, blunt, with greatly reduced cups; more or less 

 thickly covered with a whitish or greenish sorediose powder, or 

 becoming rough and verrucose; usually destitute of squamules, but 

 sometimes more or less squamulose basally. 



Cups small to minute, or abortive, with an entire or minutely 

 denticulate margin; sometimes well developed with dentate margin. 



Apothecia rare, brown to dark brown, small to very minute, 

 terminal or on tips of the denticulations of the cups. 



Most of our specimens belong to the variety coniocrcea (Flk.) 

 Wainio, in which the podetia are unbranched, usually rather short, 

 sorediose, cupless, cyhndrical and pointed, or with minute abortive 

 cups; squamules absent or more or less present basally. 



Part of our material belongs to the variety simplex (Weis) Wainio, 

 in which the plant resembles a slender form of Cladonia pyxidata, 

 with simple podetia without squamules, sorediose or becoming 

 rough and verrucose, and with the cups better developed than in the 

 other varieties. 



The variety suhulata is also occasionally found here; in this the 

 podetia are much elongated, usually without cups, cylindrical or
