larger than in R. farinacea and R. dialacerala, the only other 

 local species which bear them. The European form of R. pol- 

 linaria looks entirely different. 



In the mountains farther north, rarely in southern New York 

 and New England, will be found Ramalina dilacerata (Hoff- 

 man), Torn Lichen, a small form with swollen, hollow stalks, 

 spraying out into rounded and tapered tips, and dotted with 

 white specks of soredia. The small fruits are borne only on 

 thickened tips. The inflated stalks are its chief distinguishing 

 character. 



All Ramalinas are distinguished from Usnea and from Tel- 

 oschistes by their lack of hair-like fibrils, from Usnea and Alec- 

 toria by their usually flattened and angled stalks, from Evernia 

 and Cetraria by the structure of the stalk (See Group 4) and 

 from all similar lichens by the character of the 2-celled spores.
