Can anyone help ID these mushrooms?

[Sink_or_Swim]

My boss has these in his tank and I'm obsessed - they are sort of frilly but not like hairy mushrooms... kind of see through... and pretty big, the biggest heads are probably at least 3" wide. I'm trying to get him to give me one, lol, but would like to know what type they are. (He doesn't remember).
Thanks!

I don't know the specific name, but I believe these are rhodactis.

Thank you, that helps! I am still trying to convince him to let me steal one - I haven't seen any quite like them.

+1 those look like green rhodactus mushrooms.
