Mushroom ID? Looks like a deadpool but better

Looks like a deadpool but it has yellow on the edges on it.

I have a small colony of these. They get dark red like yours in lower par and more of a pink red in high par. I got it as a freebie from aquasd. I believe they call it a flame rim disco or fire rim maybe? Things are almost as bright as my jawbreakers.
