Unusually Large Mushroom

Unusually Large Mushroom has a small chance to drop from any mob in Ardenweald, Mists of Tirna Scithe, or De Other Side. It can be planted in the Damp Loam in northwestern Ardenweald to spawn a Rapidly Growing Mushroom which eventually transforms into the rare elite Humon'gozz, who in turn drops the Arboreal Gulper mount when killed.
