Haha! Did you know that until today, I thought this thing was called OBLIVAX, but now I know that all along it has always been OBLIVIAX. 
I would prefer to attempt to stat this up as a creature rather than a hazard, unless that is just simply unfeasible.

This evil black moss has the magical power to steal memories from others. When an intelligent creature is within 60 feet it must save vs. spells or the moss will steal all the creature's memories from the last 24 hours (including memorized spells). It can try to steal from 1 creature per round until it succeeds, and then it will not attack again for 24 hours.
If an obliviax with stolen memories is attacked, it will, in 1 round, form a part of itself into a tiny moss imitation of the creature whose memories it stole. This mossling remains attached to the parent moss and can defend itself only by casting any stolen spells.
The only way to regain stolen memories is to eat the living obliviax. This takes 1 round. If a save vs. poison is made, the eater will gain all the stolen memories including spells. If the save fails the eater will become very ill for 3-1 8turns. It is possible to gain another’s memories by eating this moss. Anyone who gains spells by eating the obliviax can cast them. The memory gained this way fades in 24 hours.

Obliviax is a black moss with an evil nature and the magical ability to steal memories from intelligent creatures. It is called "memory moss" and is a bane to wizards everywhere.
Pitch colored and thick, like a luxuriant black carpet, obliviax grows in small patches and spreads through spores. Its leaves and flowers are all glossy black. When it lacks stolen memories it quivers, as if in anticipation. It smells like damp, loamy dirt, a very unappetizing odor. Although it requires no sunlight to grow, it does require daylight to trigger spore reproduction and so it does not naturally occur in subterranean realms. It can be inadvertently or purposefully carried into a cavern, where it will grow but is unable to reproduce.
Combat: Memory moss can sense the approach of sentient beings; once they are within 60 feet, the moss can attempt to steal their memories. It is selective, first attempting to steal wizards' memories, then priests', then any other spellcasters', then any other characters'. When an intelligent creature enters the obliviax's sphere of influence and is attacked, it must roll a successful saving throw vs. spell or lose all memories of the last 24 hours. These stolen memories give the plant vitality and nourishment. Any creature who has lost memories acts baffled and disoriented, often forgetting important events and knowledge, with nothing but a blank in his memories since the previous day.
If an obliviax with stolen memories is attacked, in one round it forms a part of itself into a tiny moss imitation of the creature whose memories it stole. This mossling remains attached to the parent moss and defends the plant by casting any stolen spells. This is the moss's only defense.
To regain stolen memories, a victim must eat the living obliviax, which takes one round. If a saving throw vs. poison is successful, the eater gains all the stolen memories and spells. If the saving throw fails, the eater becomes very ill for 3d6 turns.
Habitat/Society: Obliviax grows in tropical to temperate climes, but cannot abide too much water or cold. It does not grow in desert terrain. It is not uncommon to find patches on tree trunks, fallen logs, or sprouting on rotting leaves. While it does have intelligence, and is aware of other mosses nearby, it does not act in concert with those of its kind, preferring to grab for the best memories possible. Small colonies of the moss are sometimes found in tunnels or caverns, either grown from sprigs of moss tracked in by some unaware creature, or sprouted from spores blown in by the wind.
Ecology: It is possible to gain another's memories by eating the moss. Anyone who gains spells by eating the obliviax can cast them, but the memories fade after 24 hours. Evil creatures sometimes transplant obliviax near their lairs so it acts as a guardian. Obliviax powers cannot penetrate lead, so the moss can be carried to a new location in a lead box. Spies use this lead box trick to snare secrets from unsuspecting victims.
A potion of forgetfulness can be distilled from obliviax, and its spores can be distilled into an elixir to restore the memories of the forgetful or senile.

Obliviax, or memory moss, is an evil black moss with the ability to steal memories, even memorized spells. It grows in small patches and must have sunlight to spur reproduction by spores, though it needs no light for growth. It prefers a balance of wet and dry, and cannot abide cold temperatures.
The moss senses intelligent creatures within 60 feet; it chooses one, preferring wizards, then other spellcasters. This victim must make a saving throw vs. spells or lose all memory of the last 24 hours. The obliviax continues to attack once per round until it succeeds and then makes no more attacks for 24 hours. If an obliviax with stolen memories is attacked, it forms part of itself into a tiny moss imitation of the creature whose memories it stole. This mossling remains attached to the parent moss and defends it by casting stolen spells.
To regain stolen memories, a victim must eat the living obliviax, which takes one round. If a saving throw vs. poison is successful, the eater regains all stolen memories and spells; if the saving throw fails, the eater becomes very ill for 3d6 turns. Extra memories and spells can be gained by eating obliviax which has fed on someone else recently. Spells can be used by the eater, but all such memories fade within a day.
A potion of forgetfulness can be distilled from obliviax, and its spores can be used to make an elixir to restore the memories of the forgetful or senile.
