The following errata have been found to exist in earlier versions of Kinoko. These issues may already be fixed, depending on when you purchased the book.
In the story How I Find Mushrooms, the image of the white boletes (Boletus orientialbus) was mistakenly labeled as "Kumotake." It should be "Shiro-yamadoritake" instead.
There is a mistake in the translation of the haiku by Naka Kansuke (1885 - 1965). The haiku should read Wolves wander along / mountain trails, their ways lit by / moonlit-night mushrooms.
Feel free to contact the author if you find anything else that looks wrong.
