What is my mushroom doing? Long Brown filament...

This popped up today on my mushroom... I first thought it had just caught ahold of something floating in the tank and suctioned it off... But 20 minutes later it was back. I have never noticed a mouth on this thing before but this seems to be coming out of it.

Thoughts?

Lol, I have had it for a while now and never seen it do this.
