Mushroom? ID please

[jonny]

I got this shroom on a large assorted rock that I didn't want it growing on. I assumed it was a shroom that had split 2 heads off of the main one, but I cant see mouths on the smaller ones, and it doesn't seem to be growing out at all..ideas?
Its red with a barely visible green rim.

Just another of the many species of shrooms

Kinda what I though..its just very strangely shaped so I was a little confused lol

 

[Reeferey]

Got some just like it- any clue to what they are?

 

[StevenBell]

Both look like Actinodiscus sp. The first one could be growing strange because its on what appears to be a really small frag plug.

It was growing that way on on the rock I took it from..it detached from the rock frag due to high flow...its now on an old feather duster tube lol

Could be just ready to split.They do this by fission
