The danger they pose lies in the paralyzing effects of their skin secretions which can be brought about by mere contact. Their threat to humanoid settlements is minimal, though sometimes they spawn in great (and even plague-like) numbers. They are easily killed when in their immobile, mushroom-like state, though their contact poison is just as dangerous - and remains so a full day after their death.
Frungi are occasionally sought after by alchemists and others for the more esoteric, vision producing use of their poisonous secretions.

Note: Magic users and clerics ingesting the poison of a frungus (either by brewing a tea or soup from them, or just through licking) will become paralyzed (no saving throw) for a full day, at the end of which they’ll experience one of the following:
1. Water Breathing, per the 3rd level MU spell.
2. Clairvoyance, per the 3rd level MU spell.
3. Clairaudience, per the 3rd level MU spell.
4. Contact Other Plane, per the 5th level MU spell.
There is a 1% cumulative risk of the loss of sanity with each ingestion.
