In rivulets. — But for its definite gelatine, this species would not differ 

 from Conferva. 



88. Ch^etophora. Ag. Chaetophora. 



Frond gelatinous, globose, or lobed, rarely plane and crusta- 

 ceous, composed of numerous filaments aggregated together and 

 issuing from a common base. Filaments articulated, branched; 

 articulations of the brandies subhyaline, those of the ramuli 

 coloured. — Name; yjurri, a bristle, and fogsw, to bear; the ra- 

 muli are, in some stage of growth, tipped with long setaceous 

 points or bristles. 



1. In fresh-water. (Chaetophorae genuinse.) 



1. C endivicefolia, Ag. (branching Chcetophora) ; frond 

 elongated filiform somewhat compressed subdichotomously 

 branched. — Ag. Syst. Alg. p. 28. — Ulva incrassata, E. Bot. 

 t. 967. 



In lakes and streams, frequent. — A beautiful object under the micro- 

 scope, and interesting, as it connects this genus with Draparnaldia. 



2. C. tuberculosa, Hook, (tubercular Chcctophora) ; frond at 

 first globose and firm afterwards much lobed fragile and hollow, 

 filaments very slender flexuose hyaline, ramuli coloured palma- 

 to-fasciculate. — Hook. Scot. II. p. 76. — C. pisiformis, ; 3. tuber- 

 culosa, Ag. Syst. Alg. p. 27. — Bivularia tuberculosa, E. Bot. 

 t. 2366. 



In boggy pools. 



3. C. elegans, Ag. (elegant Chaetophora); " frond subglobose 

 gelatinous solid green, filaments subdichotomous, ramuli fasti- 

 giate attenuate the apices produced beyond the gelatine."
