Type of mushroom i believe?

[Marksmen_09]

Hey guys this guy was a hitchhiker on one of my feather dusters. It appears to be a type of mushroom but I'm not entirely sure. It was attached to a very small pebble so i glued it to a frag rock. Base color is a blue-ishbrown with green tips. Any info will be appreciated, Thanks
