>Hehe. I was wondering if anyone would get it.

I sure did! :)

>It was from an early episode of "Star Trek, The Pepsi Generation", oops, meant "The New Generation". It was "Skin of Evil" from the first season. http://www.ugcs.caltech.edu/st-tng/episodes/122.html the crew was on a planet and found this river of black slime that turned out to be alive.

IIRC, it's from "Home Soil":

The lifeform is discovered on a planet that is beeing teraformed, which is killing the lifeform. It's kind of a crystal.
