Morning frost and white mushroom

Walking in the forest today, i can see a light frost and the night has been cold and the muddy roads are icy.

But when I came home, I found something strange, at first I thought it was a strong frost, but no , it was a mushroom. This mushroom was pure white, and thin and hairy, it has come in the last 7 days and even the night frosts have not stopped it from growing. The only thing is that I have no idea what kind of mushroom it is, but it is here in one place under a lot of bushes.
