Mushroom ID?

Hi all, can anyone help me ID this mushroom?

It’s about 1.5inches across

Many thanks :)

Just to add.. the yellow looks more orange but my filter has changed the colour slightly. It’s been in my tank for a day, so I’m hoping once it’s settled, a few of the ‘buds’ will grow bigger, like they were in the LFS
