112 HERRE 



Apothecia numerous, terminating the branchlets, small to exceed- 

 ingly minute, brown, varying from pale, almost flesh-color or yel- 

 lowish to dark. 



Common on earth in the redwood forests and also in the foothills. 

 Dr. Farlow, who has identified the forma phyllophora from material 

 which I mistakenly called Cladonia chlorophaa prolifera, writes that 

 he has found this form common in California. This form seems to 

 merge at times in forms of Cladonia squamosa. 



var. PINNATA (Flk.) Wainio. 



Podetia erect, I2 to 3^ inches long, slender and cylindrical below, 

 broad and stout above, dying below but growth continuing apically ; 

 sparingly dichotomously branched, the sterile tips usually narrowly 

 subulate, more or less squamulose to the summit, or rough and scab- 

 rous; not isidiose or sorediate; color whitish or greenish to brown. 



Apothecia minute or small, abundant but inconspicuous, brown 

 and blackish brown. 



On earth under woods in the foothills and mountains. 



This species or some of its varieties occur all over the world. The 

 varieties described above have been collected in all parts of the earth 

 except Africa. The variety pinnata, though Httle known, is no 

 doubt generally distributed over North America, according to Fink.
