Not necessarily related but similar when I looked at them at the same time like this. The mushroom was in the yard and the pitcher/mug came from a thrift store. Nice.
I see the green with round whiteness on top. Is that the same mushroom as this one? http://100speciesdodd.blogspot.com/2009/10/x2-not-from-around-here.html
Not the same mushroom, no! There are a lot of different kinds of mushrooms I've found in the yard. Maybe I should shart photographing all of them.
