CRYPTOGAMIA ALGiE. 895 



©f catara(5ts ; as on Goatfidd^ in Anarty and 

 many other mountains. 



It forms clofe black matted tufts, from the breadth 

 of a fhilling to that of a crown piece, confifting 

 of numerous very fine capillary filaments, about 

 a quarter of an inch long, irregularly branched, 

 and entangled together, their extremities ge- 

 nerally a little curled or curved. Thefe fila- 

 ments are not fmooth and gloflTy, but fome- 

 what rough and opake, and, when moiftencd 

 in water, are of a Ibfc flexible fubftance, and 

 dark olive colour, and, being highly magnified, 

 appear fcabby, or covered over with numerous 

 black- green leprous tubercles. We difcern'd 

 no fruftifications. The phnt feems nearly re- 

 lated to the genus of Conferva, from its delight- 

 ing in wet places, but the filaments of it not 

 being jointed, determined us to give it a place 

 among the Lichens.
