On decayed Trees in the Wood at Croftwick near Norwich. Mr. 



Hooker. 



I cannot find that this fpecies has been noticed either as a Conferva or 

 ByfTus, in which latter genus it would have been mofl probably arranged 

 by the older authors. It forms a fine fpider-like web on decaying wood of 

 a light yellow color. The filaments are branched, extremely flender, 

 flaccid, and looiely entangled : the branches are fimple, remote and difpofed 

 without apparent order : the difl'epiments are of a dark color, and divide 

 the filaments into joints, whofe length, though variable, is molt ufually 

 about four times greater than the diameter. I am not aware of its having 

 been found by any other Botanift than Mr. Hooker, and to him I am 

 indebted for the drawing of plate C, which reprefents the plant of its 

 natural fize, and alfo when magnified with powers 2 and £ of his micro- 

 fcope.
