LICHI'NA, Ag. — A genus of Collema- 

 ceous Licheus, allied to Collema and 

 Ephebe in many respects, formerly in- 

 cluded among the Algae on account of their 

 growing on the sea-shore (near high-water 

 mark), "but having the thallus of a lichen 

 and bearing true apothecia and spennogonia. 

 The globose apothecia occur at the ends of 

 the branches of the thallus ; in L. j)yi/mcea 

 the spermogonia occur underneath the apo- 

 thecia, in L. conjinis at the apices of the 

 branches and often on the apothecia. The 

 spores, 8, simple, appear generally to adhere 

 to the walls of the thecse, which break up. 

 Spermatia oblong.

LIGAMENTS and Tendons.— With the 

 exception of the elastic ligaments, which 

 are noticed under that head, the structure 

 of ligaments and tendons is essentially the 

 same. They consist of fibrillar connective 

 tissue, with a small quantity of elastic 



Magnified 60 diameters.
