Can you post a picture of your specimen(s)? Plant-like formations can be fossils, but moss agate has formations that look like plants and there are others. Any information on where the rock was found would also help.

It sounds like you are talking about dendrites, a kind of magnesium oxidide that create black, plant like shapes on a rock or mineral.
