After deciding on "mushrooms" as my theme, I've become quite knowledgeable about them while researching various kinds. There's a certification for fungal instructors, and I might try to get it someday. My love for mushrooms is overflowing, so this autumn I even got mushroom-patterned pajamas! There are a total of 12 different kinds of mushrooms depicted on these pajamas. The blue mushroom is the blue-green mushroom. The red one is the fly agaric, and the yellow mushroom is the chanterelle. If you can identify all the remaining mushrooms, you're already a mushroom expert.
