Wherever this little Fucus is found, it covers whole mafles of 

 fiones in the manner of Lichens. From its great likenels to this 

 genus, we have changed the uninterefting names of Mr. Lightfoot 

 and Mr. Hudfon to Lichenoides. This very appellation will lead to 

 its distinction. 



Mr. Lightfoot was fo ftruck with this fimilarity, that his whole 

 defcription dwells upon it. — His figure is excellent. 



The fructification of this little fpecies is fomewhat lingular. 

 Generally fpeaking, it is a round and perfectly fmooth tubercle, re- 

 fembling a minute bladder, opening more or lefs at the top; but 

 we fee occafionally minute granulations on the furface of it.
