There are only four kinds of mushrooms to be found. My virtual lab can grow more mushrooms in a shorter time. I've discovered toadstools, too.
Sometimes I got shocked at monster-like things that may not be called mushrooms. I thought of rejecting them, but such strange things are illustrated as Nameko-to-be-grown in the list. So growers should admit that they have "mushroom rights."
Business as usual, anyway.
