God's Eye Mushrooms

My coworker Jester is a horticulturist specializing in mushrooms. 
He leads foraging outings throughout the summer on a friend's wooded land; teaches classes; cooks, grows, and paints pictures of mushrooms.

I showed him my God's eye in the colors of a monarch butterfly (at end of post), and he suggested the purple and grey Laccaria mushroom would make a nice God's eye too--and the popular red-with-white-spots Amanita.

This morning I made them. 
I have variegated purple yarn, and the Laccaria was easy enough to approximate. (Hm, should add some dark brown.)

Laccaria Ochropurpurea

But I haven't yet found a way to spatter dots across this square form... A fun enough first try, but more experimentation is needed to produce a proper Amanita Muscaria.
