Did mushrooms originally come to earth on a meteor?
It is an interesting idea that life may have come from other parts of the Universe, but there is no evidence that this really is so (nor that it isn't, for that matter). Also, specifically in the case of mushrooms, despite all their differences, they are probably too similar to other life on Earth to have evolved independently from it. If life did come from outer space, it may have been a common ancestor to ALL current life on Earth.
