I have some of the encrusting types Canadian_Man and SamW speak of, except that I have blues, yellows, and lately I am noticing a magenta hue to some of them. Some of the yellow ones do start to get a shape to them, I have one in my 75g that's about half the size of a golfball, but fairly spherical.
Some of the yellow ones that popped up in my sump have been around for years. I have no idea how well the stuff transfers although I did give a piece to Tau2301 at the last Calgary meeting so I guess we can see if the stuff lives if it's taken out of one setting and put into another.
Some of the white stuff doesn't seem to fare well when out in the open. For example I had some on the underside of a rock, that got exposed when I moved the rock from one tank to the other (I was tearing down my 50g at the time). That one seemed to disappear. Whether this was because of sudden exposure to the light, exposure to air for a few seconds, or a lack of acclimitizing, or starvation, or whatever the case ... I haven't a clue.
