beiformis Ach. (Plate IV. a.) The thallus is round (terete) except at the 

 joints, where it is flattened. In color it is almost black, shiny and rigid, and 

 grows in tufts. The branches are finer at the tips, and of one color. Soredia 

 are usually found, which are interesting on account of their shape. Instead of 

 being in round, mealy-looking masses, seemingly sessile on the thallus as in 

 Usnea, they are whitish, oval bodies, which seem to be imbedded in the thallus. 

 A/ecfortajubatavar.imp/exa Fr. (Fig. i.) Thallus pendulous, quite soft, 

 with many branches, which are intertangled and turn back on each other. It is 

 a much lighter brown than chalybeiformis, and does not have the varnished 

 appearance. While this species is found in the eastern States, it grows more 

 luxuriantly in the far West, where with one or two other species it is generally 

 called by travelers "Florida 

 Moss," as it hangs from the 

 trees in long masses 



Alectoria ochrolenca (Ehhr-) 

 Nyl. var. sarmentosa Nyl. 

 (Fig. 2), is also found in the 

 East, but is rare; in the West 

 it is very common. The thal- 

 lus is pendulous, but not as 

 soft as in hnplexa. The color 

 is a light, greenish-brown, 



sometimes straw-color. The branches are long and much divided 

 not turn back as in impkxa 

 color. 



Alectoria Fremontii Tuckerm. (Fig. 3. ) The thallus is a very dark brown, 

 wavy and shiny, with few branches, which are quite straight until toward the
