Insane In The Shroombrane

This blip is brought to you by one of the Portobello Mushrooms that became sandwiches for dinner. There's occasionally a very pretty, very fluffy, membrane of sorts, found on the underside of mushrooms. These are apparently called the annulus, ring, or collar of the mushroom... and YES... I had to look that up, but now we know stuff! Anyway, so I gently pulled this off, curled it around itself, and a seashell was born!
