Baby Toadstool Yellow??

[GeoSquid]

ok, I have a toadstool on this rock that has split in two a year and half ago or so and both of them have traveled around the rock looking for the right spot. They have already left one baby that is a couple inches tall already. None of the current toadstools have moved in like a year and I just noticed these on the rock. I'm assuming they are baby toadstools, but they are yellow. It's weird they are yellow and popping up so long after the other ones were moving around. Has anyone seen this before? These are the best pics my phone would take...a little blurry.

Possibly a small leather, but need a clearer picture to be sure.

I was just wondering if anyone had a yellow toadstool coming from a brown/pink verity. Maybe it will change color back to normal as it matures.
