Farrik Foe Cleaver

Farrik Foe-Cleaver is an Ogre who's weapon of choice is a great club, but has a weakness for fungii. If you go looking for him in House Jorasco, you can find him near the center of that section of the city, perched on a balcony behind the house. In exchange for any fungus you might have run across on your journeys, he'll give you some potions or a suit of magical armor, depending on the rarity of the fungus.

See here for details on the fungii he's looking for, and the rewards he hands out.
