This is about the most brilliant supplement for TTRPGs that I have ever seen. Not only is it a physically beautiful book, it also explores a subject that most gamers have likely never included in their game scenarios, creating a wealth of opportunities for new experiences.

Author Alex Clements has constructed his material in a completely system-neutral way, so all of these great fungi can be easily adapted into any game that you happen to be playing. And on another level, the book is just fun to read, with the wonderful color printing really highlighting Shuyi Zhang's ability to render each species with a unique personality. Just great stuff all around!
