Clear plant-like with roots

[JEBoothjr]

I have some of this stuff growing in my sand. I can't get a picture of it, because I don't have a good enough camera to get that close. It's growing out of my sand. I have a few clumps of it in different spots of the tank. It's kind of transparent white finger shapes poking out the surface, tapering slightly, kind of like sprouts of something. Some of it grows by the glass, so below, you can see a definite root system. The biggest sprout is maybe 1/2in, but most are aroun 1/8 and smaller. Any clues are appreciated. Thanks.

sounds like algae . Is this a planted tank? J/K take it out by hand if you can, unless you like it, then leave it.
