- "Dank or dangerous, high or low, where none dare tread, the fungi grow."

Mushrooms are a type of fungi frequently found growing on the many trees of the Louisiana Bayou.
During her career as an Assassin, Aveline de Grandpré scoured the Bayou for these mushrooms, amassing a vast collection that proved useful in curing people suffering from Bayou Fever. The mushrooms could only be administered while the victim was unconscious.
- The "Mushroom Queen" achievement can be earned by collecting all the mushrooms, while the "Bayou Fever" achievement can be earned by curing all of the fever's afflicted victims.
