rows ; basally more or less warty or sub-squamulose ; above 

 more or less naked ; cups dilated, with margins more or less 

 denticulate or proliferous ; within usually granular warty or 

 even squamulose ; apothecia small, brown. 



On earth and rock, at an elevation of about 1000 feet, on the 

 Page Mill road, Black Mountain. 



Probably not uncommon in the mountains above 1000 feet. 



Cladonia -pyxidata is a very variable species ; the variety cos- 

 tata is distinguished from the typical form of the species by the 

 podetia being longitudinally furrowed and more or less naked. 

 Cladonia pyxidata costata Floerke, Clad. Comm. 66. 1828. 



2. CLADONIA CHLOROPH^A Floerke. 



Squamules of primary thallus crenate-lobed, rather broad, 

 medium size to large ; usually ascendant ; green to ashy or olive 

 brown. Podetia simple, short, broadly turbinate, rising from 

 center of squamules ; covered with a yellowish-greenish or sul- 

 phur-colored powder, or warty granules ; cups dilated, rather 

 deep, with entire or denticulate margins. Apothecia rare, 

 brown, becoming confluent. 



Occurring throughout on earth and stumps. 



2a. CLADONIA CHLOROPH^A PROLIFERA Arn. 



Podetia elongated and comparatively slender ; cups but little 

 evident, their margins greatly extended in branched prolifera- 

 tions ; these flattened or expanded and more or less densely 

 clothed with leafy thalline lobules ; summits terminated by the 

 abundant, minute, light brown apothecia. 



A peculiar form resembling Cladonia squamosa in the abun- 

 dant squamules on the thallus, and in habit and general appear- 

 ance like a very stout and coarse condition of Cladonia furcata 

 racemosa. " Habet podetia scyphosa qua C. /areata non 

 habet," Zahlbruckner /« ////. 



On earth in the redwoods above Woodside, at an altitude of 

 1200 feet.
