Hi, Andrew -- Volvox is a spherical green alga that is generally  
microscopic, although some of their colonies can get big enough to be  
just visible to the eye, I think.  And they should be actually green,  
as opposed to the bluish green that most Cyanobacteria show (blue- 
green bacteria).  Jim in Wolfville.
