CONFERVA LANUGINOSA. 



C. filamentis fub-fimplicibus minutiilimis, ferrugineis ; articulis longiuf- 

 culis, medio-pellucidis ; capfulis feffilibus fecundis. 



In the Sea, adhering to other Confervce. At Swanfea, common. 



THE filaments of C. rubra and fome other fpecies of Confervas often aflume 

 a ragged appearance as if in decay : and it was with equal pleafure and furprize 

 that I found this appearance occafioned by the prefent elegant parafite which is 

 fo extremely minute that the higheft power of the microfcope is hardly fuflicient 

 to afcertain its ftructure. The filaments are fometimes fimple and fometimes 

 branched, but I have never been able to find more than two branches on the 

 fame filament : the capfules are round and fefhle, and when two or more appear 

 together, as is frequently the cafe, diey are always difpofed on the fame fide of 

 the filament. 



It differs from C. cirrofa, for which alone it might be miftaken, in its much 

 fmaller fize, ferrugineous colour, and pellucid joints. In fize it agrees with C. 

 nana, but differs in almofr. every other refpect : lanuginofa is moreover a marine, 

 nana a frefh water fpecies. 



In drying it adheres to either glafs or paper. 



A. C. lanuginofa, growing on C. rubra, natural fize. 



B. Ditto magnified i.
