Black Root Fungus
The most disgusting thing I've ever tasted grows on the most delicious thing I've ever tasted. Black root fungus is some weird kind of fungus that grows commonly on the spice, and it is used as a rite of passage for those in the Cherry Tribe. If you can stomach the fungus, you are officially part of the tribe.

Aw, man, ostracized because I don't dig on fungus?! No fair, man. (in all seriousness: nice work here)
Don't worry, you're not missing out on much if you're not one of the Cherry Tribe :P (thank you so much!)
