Original Library[]
The Funghi Library stores information on the various different Funghi that you cultivate in Mushroom Garden (aka Funghi Gardening Kit). This original Library contains 30 different varieties.
Mutant Library[]
Once you collect the 30 funghi in the original library a Mutant library with an additional 24 funghi opens up for you. The Mutant library is added as a part of the original library.
