BURT THELEPHORA.CEAE OF NORTH AMERICA. V 739 



Fructifications 2^-5 cm. high, 7 mm.-2 cm. broad; stem 

 about 1^ mm. thick. 



On ground in woods. Canada to Mississippi and westward 

 to Missouri. August and September. 



The fructification of this species is smaller than that of T. 

 candidum and has but few branches, which are often arranged 

 in a circle about the end of the stem so as to appear some- 

 what proliferous on the margin of an imperfect cup as in some 

 species of the lichen, Cladonia Whence the specific name or 

 with the branches standing up side by side from the com- 

 pressed apex of the main stem. Both forms of branching have 

 been found so associated in the same collection as to preclude 

 the possibility of regarding this difference as a basis for two 

 species. The branches are so frequently in threes that **tri- 

 faria*' was contemplated as a name for the species by one 

 author.
