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

 ftones in the manner of Lichens. From its great likenefs to this 

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

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

 its diftindlion. 



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

 defcription dwells upon it. — His figure is excellent. 



The fru6lification of this little fpecies is fomewhat fingular. 

 Generally fpcaking, it is a round and perfeftly fmooth tubercle, re- 

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

 we fee occafionally minute granulations on the furfacc of it.
