This is by no means an uncommon species during the spring 

 and early part of the summer, being found attached fre- 

 quently to dead leaves and sticks. In the fineness and mucosity 

 of its filaments, as well as in the shortness of its cells, it seems 

 to exhibit some relation to the genus Chcetophora (a bad name, 

 since the species of the genera Batrachospermum and Drapar- 

 naldia are likewise chaetophorous). From D. tennis and D. 

 elongata it is distinguished by the absence of cilia, shorter 

 cells, and from the former again by its smaller size. 



9. CH^ETOPHORA Schrank. 



Char. Filaments imbedded in a gelatinous matrix, which is 

 either globose or lobed, rarely plain and crustaceous ; ag- 

 gregated, branched, articulated, sometimes setaceous, and 

 issuing from a common base. Branches nearly colourless. 

 Ramuli coloured. Capsular fructification has only been 

 noticed in C. pisiformis, C. pellita, and C. tuberculosa. 



Derivation. From %atr?7, a bristle, and (fropso), to bear.
