What kind of mushroom is this?

[Chicken_Biscuit]

I got a free mushroom as a freebie but have no idea what kind it is. I’m not a fan of mushrooms and don’t seek them out but I got these two for free. Could you guys help me ID them please? Thank you!

Big one looks like a ricordea yuma to me. Can't really see the other

Are these the ones that have a chance to form a tumor?

I believe it's rhodactis mushrooms that have the ability to become 'bounce' mushrooms.
It's possible the small one on the right is a rhodactis mushroom, but i can't see it well.

My rhodactis closes up when spot feeding, unlike my ricordea, it doesnt really close up when feeding
