Mushrooms while strolling around the park

Hi community!
Recently I am developing a passion in taking pictures of the mushrooms I bump into while visiting nature or just walking around: it is so much fun!
I was considering mushrooms either as a wonderful food, either I was not interested in them almost at all...but here I am, excited while taking pictures of random mushrooms with my bad phone camera :)

Mushrooms in the picture above look pretty interesting to me: they seem to be kind of molten on the edge. I was thinking they were with mold, or however diseased, but looking around all the mushrooms of this kind were in this condition. Neat!

I have no clue on how to give a name to all those little beauties, maybe you could help! Any contribution is warmly accepted ;)
