This is growing in Bostick's yard. I'm not sure it's really a mushroom. I think it might really be an alien life form and if you get too close to it, that little tongue at the bottom may flick out like a frog's and shoot spores into your eyeballs.
Anyway, I'm on the work rotation through Thursday, so go over check out what else is springing up in Bostick's world while I put together a post. It's a lovely place, I promise you won't be disappointed.
