PELTIGERACEAE 

 Sticta amplissima {Scop.) Mass. 

 Trees and rocks. Very common. A large fine species. 



Sticta pulmonaria (Z.) Ach. 

 Trees and rocks. Common. Often growing on the same tree with 

 the preceding species. It once had some repute as a remedy for pul- 

 monary diseases. The disks of the apothecia are sometimes blackened 

 by the attacks of a parasitic fungus. 



Sticta crocata (Z.) Ach. 

 Among mosses on rocks. Vicinity of Lake Placid. Atkinson. f 



Sticta scrobiculata {Scop.) Ach. 

 Same habitat and locality as the preceding one. Atkinson. 



Nephroma arcticum (Z.) Fr. 



Rocks. West side of Pitchoff mountain near the old Keene road. I 

 discovered this northern lichen here many years ago and this still remains 

 the only known station for it in our state. It is a large fine species with 

 broad and beautiful apothecia. It is earnestly hoped that forest fires 

 may never come near enough to destroy it. 



Nephroma Helveticum Ach. 

 Trees and rocks. Freemans Home and Indian pass trail. 



Nephroma laevigatum Ach. 

 Rocks. Old Keene road. 



N. laevigatum parile Nyl. 

 Near Lake Placid. Atkinson. 



Peltigera aphthosa (Z.) Ho§-m. 



Damp mossy ground, shaded banks or among mosses on rocks. 

 Common. This is easily distinguished from all our other species of 

 Peltigera by the scattered warts of the upper surface of the thallus. 



Peltigera horizontalis (Z.) ffoffm. 

 Pulpit rock on the shore of Lake Placid.
