 Chsetophora pellita, Lyngb. Chsetoderma pellita, Ktz. 

 Hob. On Bmooth exposed rocks and stones, between tide-marks. 

 Perennial. Fruiting in February. 

 Where a considerable surface of linked and Bmooth 

 is exposed between tide-marks, it may commonly be ob- 

 irved to be covered here and there with skin-like patches 

 >f a dull red or olive-green, formed by the plant here 

 figured, which adheres so closely to the surface of the 

 rock thai it can only be removed in flakes by scraping with 

 a knife. It was first noticed on the sh< Norway 



and the Ferroe [slands, and has since been found in many 

 places along the Atlantic coasts of Europe, and probably 

 in many others where hitherto it has been over- 

 looked.
