Personally, I welcome them! The only alternative I can think of at this moment would be to repot the plant into a sterile medium but you might still end up transferring some of the biology from the last pot.

There may have been some spores in what you collected.
As Timothy suggested you could repot the plant into a sterile medium.

I'm guessing they are a "pioneer" type species (don't know if there's a more specialised term for fungi) - appear, eat all of whatever it is they like eating, produce a lot of spores, then die off. I'd think if you just leave them alone, they'll disappear eventually.
