68. Vaucheria.—This is one of the most common of the 
green Algee, occurring in felt-like masses of coarse filaments 
in shallow water and on 
muddy banks, and also 
commonly found on the 
damp earth and pots of 
greenhouses. It is often 
called green felt. The 
filament is very long and 
usually branches exten- 
sively; but its great pe- 
culiarity is that there is

no partition wall in 
the whole body, which 
forms one long con- 
tinuous cavity. This 
cavity is full of cyto- 
plasm, and embedded 
in the cytoplasm are 
very numerous chloro- 
plasts and also numer- 
ous nuclei (Fig. 100).
