?^2 CRYPTOGAMIA ALGJE. 



We doubt whether this be a diftind fpecies fn'i 

 the former. It differs however from it in e 

 following refpects : The ftalks grow more :i 

 clufters, are more repeatedly branched, and t - 

 minatcd in lliorrer forks or horns, and are gei- 

 rally more foliaceous. Their colour is co- 

 monly white, fpotted with green, but are i - 

 quently aih-colcur'd, and often fufcous, ef . 

 cially the young plants, 2nd the forks of 1; 

 old ones. The tubercles are rarely found. Tl^ 

 grow on the points of the forks, and are fm; , 

 round, and reddifn.

 and foliaceous, as figured by Diiknius, H\ 

 mufc. I. 16./. 27. Z),

So far as v.'e can judge from our own fpecime , 

 and thofe of Dillenius at Oxford, we are incliiji 

 to think that this is no other than a variety 'f 

 the preceding. 1 he young plants in both 'c
