This phenotype sounds like flocculation. Normally, this happens when cells
are mating, because the mating process causes the expression of agluttinins on the
surface o the cells that make them stick to their partners.

Other mutations that affects cell wall etc sometimes have this phenotype.  Sometimes
it is just there.

Kinda cool to look at.
