Help! Mushrooms!

[JackyBlu]

I'm in the midst of cycling my tank for some P. Waltl. But this morning while I was testing, I found these tiny white mushrooms growing on my cork bark above the water line. While I like the way they look, I want to be sure they're not dangerous to my future inhabitants. The only information I've found on these specifically is on this webpage and then a few sporadic posts on here about fungus in general.

If anyone could ID these and tell me if they're dangerous, it would be amazingly helpful.

I can't ID them for you sadly. However, I would say that when in doubt, take it out. It would be a real shame if anything were to happen to them when it is such an easy solution.
