Same as above, Inn with subulate podetia v frequently bearing 



apothecia, cups when present as above, but smooth inside. 



47. ('. ochrochloTQ 



Podetia cupless, or cup-forming, in material seen scarcely cup-forming, 

 but with a slight dent at top of cylindrical podetia; resembling ('. coni- 

 ocraea, but distinguished by the presence of the bases of the podetia of 

 outgrowths of an isidioid character, in the form of coarse granules or 

 minute squamules, simple or sparingly lobed. KOI I -f pale yellow, which 

 also distinguishes the species from C. coniocraea, in which the reaction is 

 brown. 



44. C. borbonica 



Cups deep and often large, simple, dentate or much varied by extensive 

 and amply fruiting proliferations, either on stipes or smaller cups; granu- 

 late or more or less squamulose, in some forms densely so. KOH — . 



37. C. chlorophaea 



Like the above, but with farinose, rather than granular soredia; podetial 

 cortex not verruculose as in C. chlorophaea, but with smooth, flat areoles. 



38. C. conista 



Like preceding, but with taller cups, sometimes covered with soredia, 

 on inner and outer surfaces, KOH-|- brownish. (PI. 3, f. 7.) 



39. C. fimbriata 



Cups shallow and small, irregular, or usually lacking and replaced by 

 subulate apices which are often fertile. KOH — . 



45. C. pityrea 



Podetia slender, cylindrical or sub-cylindrical, rarely abortively cup- 

 bearing, simple or branched, solitary or in groups, erect or flexuous, cor- 

 tex warty or with small areoles, sometimes squamulose toward base; 

 cups when present in axils of branches, apothecia terminating all podetia, 

 pale brown or flesh-colored. (PI. 2, f. 3.) 



48. C. botrytes 



Primary squamules small, medium to large; podetia simple and club 

 shaped, or with short branches. 



Podetia grayish-green to olivaceous, cortex continuous to areolate, sur- 

 face sometimes flattened or depressed. 



Primary squamules somewhat erect and densely crowded, podetia naked 

 or squamulose, CaCl (KOH) bluish green. 



46. C. strepsilis 



Podetia short and slender, or stout, obconic, usually somewhat branched, 

 smooth or squamulose. KOH, -f- yellow, followed by brick red, the only 

 Cladonia with this color reaction, positvely identifiable when it appears. 



31. C. subcariosa
