@Varana Thanks! I didn't find the contents of the motif parts anywhere. But from that it becomes a lot more clear what a ferrofungus is.
Where can I find the rest?
Strain E-02-K:
Large to huge, drooping caps, gray. Subject's first attempt to consume a fully mature specimen resulted in the loss of several teeth and a minor stress fracture to the lower mandibular enhancement. Factotums coaxed subject to make a second attempt with an immature, smaller specimen. Subject extracted and ate the warts on the stalk with no ill effect. Note: Attempt to create weapons and armor out of mature stalks.
